22. THE AFTERMATH OF EDESSA. ŠĀBUHR I’S SECOND ONSLAUGHT AGAINST THE ROMAN EAST.
The immediate aftermath of the battle of Edessa had two immediate consequences. The first one was that the victorious Sasanian army again crossed the Euphrates and pillaged the Roman eastern provinces to a much larger extent than it had done after Barbalissos. The second and for the Romans far more serious consequence was that it caused a political crisis in the Roman empire that almost led to its dissolution.
We’ll deal first with the immediate consequences for the Roman eastern provinces and after that we’ll deal with the effects for the Roman empire at large. As usual, I’ll start with the version of the facts as stated in the ŠKZ:
And Syria and Cilicia and Cappadocia were burned with fire, ruined and plundered.
This time we seized from the Roman Empire: The town of Alexandria on the Issus (modern Alexandretta) with surroundings; the town of Samosata with surroundings, the town of Katabolos with surroundings; the town of Aegaea with surroundings; the town of Mopsuestia with surroundings; the town of Mallos with surroundings; the town of Adana with surroundings; the town of Tarsus with surroundings; the town of Augusta (Augustopolis) with surroundings; the town of ... with surroundings; the town of Zephyrion (modern Mersin) with surroundings; the town of Sebaste with surroundings; the town of Korykos (modern Kız Kalesi) with surroundings; the town of Anazarbus with surroundings; the town of Castabala with surroundings; the town of Neronias with surroundings; the town of Flavias with surroundings; the town of Nikopolis with surroundings; the town of Epiphania with surroundings; the town of Kelenderis (modern Aydıncık) with surroundings; the town of Anemurion with surroundings; the town of Selinus with surroundings; the town of Miyonpolis with surroundings; the town of Antioch with surroundings; the town of Seleucia (probably Seleucia in Pieria) with surroundings; the town of Dometiopolis with surroundings; the town of Tyana with surroundings; the town of Caesarea (Caesarea Mazaca, modern Kayseri) with surroundings; the town of Comana (modern Şar) with surroundings; the town of Kybistra with surroundings; the town of Sebasteia (modern Sivas) with surroundings; the town of Birtha with surroundings; the town of Rhakundia with surroundings; the town of Laranda (modern Karaman) with surroundings; the town of Iconium (modern Konya) with surroundings: altogether thirty-six towns with their surroundings.
And people who are of the Roman Empire, non-Aryans, captive we deported. In Ērānšahr in Pārs, Parthia, Xūzestān, Āsūrestān, and in any other land where our own and our fathers’ and our grandfathers’ and our ancestors’ estates were, there we settled them.
Again, a truly hair-rising list, and in this case with full corroboration by Graeco-Roman sources, much more than in the case of the aftermath of Barbalissos. This time, Syria Coele escaped relatively unscathed compared to seven years earlier (although Antioch was looted and burned a second time), but the main brunt of the Sasanian offensive was directed this time further north, against the Roman provinces in Asia Minor. Cappadocia and especially Cilicia were the main victims, but the Sasanian offensive reached further east, well into Lykaonia and even into Lycia and Pamphylia, the westernmost city in that list is Korykos on the southern Anatolian coast, which is located nearer to the Aegean sea than to Syria.
Detail from one of the triumphal rock reliefs of Šābuhr I at Bīšāpūr; looking at the figure standing on the left you can appreciate the long broadsword that was typical of early Sasanian cavalrymen. This was a heavy and contundent weapon, ideal for cavalry use. In the VI century CE it was abandoned in favor of lighter saber-like swords under Central Asian Turkic influence.
In order to bring about so much devastation, the armies of Šābuhr I must’ve had to be divided into several columns in order to cover as much ground as possible. But contrary to what had happened in 253 CE, this time the Romans had reserves relatively untouched by the defeat at Edessa and leaders who were disposed to rally them and fight back, and the Sasanian forces ended up suffering several minor setbacks during their looting spree which eventually forced the šāhānšāh to regroup his armies, cut his losses and return to his homeland. It’s also important to note that according to at least one ancient source Šābuhr I did not manage to take Edessa, and so he had to cope all the time (especially during his retreat) with the actions of the important Roman garrison stationed there.
The crossing of the Euphrates possibly happened at Zeugma, which was just 80 km west of Edessa and Carrhae and 40 km west of Batnae, which according to Coloru could’ve been the probable location of the battle. This time, the cities and towns destroyed by the armies of Šābuhr I are quoted in geographical order from east to west and from south to north, and so it’s more difficult to reconstruct the advance of the several Sasanian columns. But possibly, at Zeugma the army split in two, with one group heading north and looting Samosata while the other (probably under the command of the king of kings himself) again headed towards Antioch. According to Andreas Golz and Udo Hartmann, probably Mareades accompanied him again as he’d done in 253 CE. This time, the trick of having Mareades’ supporters open the doors from inside the city would not have worked (it’s hard to imagine the Antiochenes being very enthusiastic about repeating the experience of seven years earlier) and Šābuhr I would’ve been aware of that, so that if the city had to be besieged, the most logical thing would’ve been to take first at least its port of Seleucia in Pieria, and perhaps Alexandria ad Issum as well. According to several bits and snips of local Antiochene tradition which have arrived to us through the works of Libanius, Ammianus Marcellinus, John Malalas and Evagrius, this time the Sasanian forces stormed the city by surprise, thanks to the (for the Antiochenes) unfortunate fact that their walls were so absurdly long. According to a vividly written fragment by the IV century CE Antiochene author Ammianus Marcellinus, the Sasanian soldiers appeared suddenly descending from the steep slopes of the Silpius Mons while a good part of the population of Antioch was in the theater watching a play. The theater was built with its cavea excavated on the slopes of the mountain, and it was one of the actors on stage who first saw the approaching Sasanian soldiers (who presumably had infiltrated through some unguarded sector of the wall in the higher part of the mountain) and alerted the public, who began to flee as Sasanian arrows began to rain over them. This is the fragment of Ammianus’
Res Gestae where this story can be found:
For it happened one day at Antioch, when the city was in perfect tranquillity, a comic actor being on the stage with his wife, acting some common scene from daily life, while the people were delighted with his acting, his wife suddenly exclaimed: `Am I dreaming or are the Persians here?' The audience immediately turned round and then fled in every direction while trying to avoid the missiles which were showered upon them. The city was burnt and a number of her citizens killed, who, as is usual in time of peace, were strolling about carelessly, and all the places in the neighborhood were burnt and laid waste. The enemy, loaded down with plunder, returned without loss to their own country after having burnt Mareades who had wickedly guided the Persians to the destruction of his fellow citizens. This event took place in the time of Gallienus.
Possibly this very column then continued along the coast to the northwest and entered the fertile and populous Cilician plain, where they proceeded to loot and burn all its great cities: Tarsus, Anazarbus, Mopsuestia, Neronias, Dometiopolis ... and then continued further east, one along the coast which kept advancing until it reached the city of Korykos in Pamphylia (the westernmost location quoted in the ŠKZ), while another probably headed north into Lykaonia and looted the important city of Iconium. As for the column that raided Samosata, either it rejoined the main army or it continued north and entered Cappadocia. Here it could have joined forces with the column that attacked Iconium, and these forces managed to take and destroy the provincial capital of Caesarea Mazaca and the important city of Tyana.
The ancient Roman city of Caesarea Mazaca lies under the modern Turkish city of Kayseri; which is still today like in ancient times dominated by the imposing mass of the volcanic Mount Erciyes (Mons Argaeus in Antiquity).
The Via Sebaste was built during Augustus' reign and runs along southern Anatolia from Lycia to Cilicia, and it would have been one of the main routes followed by the invading Sasanian forces.
While the armies of Šābuhr I were engaged in this orgy of destruction, the remaining Roman defenders were rallying their forces for a counterattack against the increasingly dispersed Sasanian columns. That not all the main officers of Valerian’s high command were captured at the disaster of Edessa is made clear by ancient sources. According to a fragment by the anonymous continuator of Dio Cassius (that some scholars identify with Peter the Patrician), on the western bank of the Euphrates had remained a certain Fulvius Macrianus, who was probably either the
rationalis of Valerian (secretary in charge of financial affairs) or the
praefectus anonnae in charge of supplies for the eastern army, or both. According to this fragment, Šābuhr I allowed Valerian to send an envoy to Macrianus to ask for ransom, but Macrianus refused to help:
Macrinus (sic) then was Count of the (Sacred) Largesse and (Prefect) of the annona (i.e. in charge of supplies) and because he was disabled in one foot, he took no part in the battle but was expecting the troops at Samosata and received them. Shapur then sent Cledonius, who was the ab admissionibus (i.e. the person who introduced the judges to the emperor) of Valerian, to urge him (i.e. Macrianus) to come to his emperor. However, he declined to go, saying: `Is anyone so insane that he would willingly become a slave and prisoner of war instead of being a free man? Furthermore, those who are ordering me to go from here are not my masters since one of them is an enemy and the other who is not master of himself (i.e. a prisoner) can in no way be our master.' He also urged Cledonius to remain and not to return. However, he said that he would not betray the trust of one who was his sovereign. On his return he was incarcerated with the prisoners of war.
Macrianus appears also in Eusebius’
Ecclesiastical History at the start of Valerian’s persecution as Prefect of Egypt (equestrian governor), and as a staunch supporter of Valerian’s religious policies. Probably due to this and to his administrative experience as governor of Egypt Valerian put him in charge of the key office of ensuring the supplying and payment of his armies. Macrianus was thus a civilian official, not a military commander, but he controlled the military purse, which in the power void that followed Valerian’s capture turned him into a very powerful figure. He was probably acknowledged as commander by the remaining Roman military commanders in northern Syria and Asia Minor, especially by Callistus, who managed to rally the Roman defenders in Anatolia and obtained some victories against the scattered Sasanian forces there (in some sources this commander is called
Ballista, which some scholars consider that could have been his nickname among the soldiers, with Callistus being his real name). And the consequences were the usual ones: the Roman forces in this theater acclaimed Macrianus’ two sons (
Titus Fulvius Iunius Macrianus, aka Macrianus the Younger, and
Titus Fulvius Junius Quietus) as augusti. According to the ancient sources, Macrianus himself could not fill the post of augustus because he had a deformed leg.

This unexpected resistance came as an unwelcome surprise to Šābuhr I. It’s been usually considered by scholars that this second invasion of the Roman empire by the Sasanian king was just a looting raid like the first one butt Andreas Golz and Udo Hartmann hypothesize that maybe this time Šābuhr I harbored (at least for a brief time) some notions of territorial conquest. They base their hypothesis on two aspects that appear in ancient sources. The first one is that according to their reconstruction of events the Sasanian king brought again Mareades with him, but that this time he installed him as governor or viceroy in Antioch (which would explain why in some sources he is named with the honorific name
Kyriades, from the Greek
kyriós, meaning “lord”). The second (and in my opinion much more substantial) hint is the rock inscription of the mowbed Kirdēr (aka Kartir, Kertir or Karder) at Naqš-e Rajab in Pārs abbreviated as KKZ. Kirdēr was probably the most important and influential Zoroastrian priest in Sasanian history. In this inscription (dating probably to the 280s) he boasted of his long career and successes; although the zenith of his power (according to the KKZ) happened under Šābuhr I’s successors Bahrām I and especially Bahrām II, his rise began already under Šābuhr I. This is somewhat suspicious because in the ŠKZ Šābuhr I gave an exhaustive list of the members of his court and Kirdēr doesn’t appear in it. Another suspicious fact is that according to many ancient sources Šābuhr I protected the prophet Mani, and in the KKZ Kirdēr proclaims himself as Mani’s enemy and as instrumental to his execution under Bahrām I. But anyway according to the KKZ Kirdēr accompanied Šābuhr I during this second invasion and he was entrusted with the task of protecting the “Zoroastrian” believers in the conquered territories and to bring to them the “correct” Zoroastrian doctrine and practice as it was understood in Sasanian Iran at the time:
And from the first, I, Kirdēr, underwent much toil and trouble for the yazads and the rulers, and for my own soul's sake. And I caused many fires and priestly colleges to flourish in Iran, and also in non-Iranian lands. There were fires and priests in the non-Iranian lands which were reached by the armies of the King of kings. The provincial capital of Antioch and the province of Syria, and Cilicia, and the districts dependent on Cilicia; the provincial capital of Caesarea and the province of Cappadocia, and the districts dependent on Cappadocia, up to Pontus, and the province of Armenia, and Georgia and Albania and Balasagan, up to the `Gate of the Alans' - these were plundered and burnt and laid waste by Šābuhr, King of kings, with his armies. There too, at the command of the King of kings, I reduced to order the priests and fires which were in those lands. And I did not allow harm to be done them, or captives made. And whoever had thus been made captive, him indeed I took and sent back to his own land. And I made the Mazda-worshipping religion and its good priests esteemed and honoured in the land.

What does this mean? If the antiquity of Zoroastrianism has to be guessed by the oldest extant texts belonging to this religion, then the origins of Zoroastrianism can be dated at around 1000 BCE or earlier, which according to linguistic research is the estimated age in which the Gathas of Zoroaster (the oldest part of the Avesta) were composed. Thus, by the III century CE Zoroastrian tradition was already more than 1,200 years old. And most importantly, scholars agree that it would be improper to talk about a unified “Zoroastrian religion” during this time. What existed was a very diverse continuum of religious traditions that mixed very ancient Aryan polytheistic religion with Zoroastrian cultic practices. These traditions knew a great expansion under the Achaemenid empire, in which the Zoroastrian tradition was adopted by Indo-European peoples who were not of cultural Aryan stock: the Armenians and the peoples of Anatolia. These peoples became thus Iranicized in their religion and culture (hence the use of Iranian names as “Mithridates” or “Ariobarzanes” among Anatolian kings in Pontus or Cappadocia) but not in language.
When first the Macedonians and later the Romans annexed these lands, a new cultural layer was superimposed onto the two existing ones (the original indigenous one and the Iranian one) which became the new culture of the elites, but Iranian cultural and religious practices persisted amongst the common people, including cultic practices that revolved around the Aryan pantheon (the cult of the Roman Mithra originated in Asia Minor) and the worship of sacred fires.
The situation in Iran in Arsacid times had been somewhat similar, but here already some Arsacid kings in the second half of the I century CE had started religious “reforms” in order to “return” the popular religion to what they (and the priests that supported them) deemed to be the “pure and original” teachings of Zoroaster. With the rise of the House of Sāsān to the throne of Iran though, this idea of religious reform took a new impulse, due to the very active role that Ardaxšir I took in religious affairs, and to the extensive manipulation that the first Sasanian king did of the Zoroastrian religious tradition to suit his own political goals.
Šābuhr I seems to have continued with this trend of manipulating religion to suit his political agenda, but with an added twist: on one side he seems to have supported the “Zoroastrian reformation” led by the new hierarchical structure of mowbedān put in place by his father, but he also began toying with the idea of instituting a new, radical version of a “reformed Zoroastrianism” which is as he probably saw the teachings of Mani. Rivers of ink have poured over the question of Šābuhr I’s protection of Mani, but one thing seems clear: this king never embraced wholly the teachings of Mani, even if Mani even accompanied Šābuhr I in some of his military expeditions, as stated in the polemical text by Alexander of Lycopolis
Contra Manichaei opiniones disputando:
Manichaeus himself is said to have lived during the reign of Valerian and to have accompanied Shapur the Persian king during his military campaigns...
If Šābuhr I harbored ideas of territorial annexations in the Roman East, then that would explain why did he direct his offensive towards Asia Minor, which is where “Zoroastrian” communities could be found, and this would lend credence to Kirdēr’s assertion that he was charged by the King of kings with the task of promoting “proper Zoroastrianism” among the inhabitants of these regions. Notice that, true to Zoroastrian tradition, he said nothing about proselytizing but about spreading the “true teachings” of the “Mazdean religion” among those who already followed it (more or less).
But the Roman resistance put a quick end to Šābuhr I’s ambitions. The dispersed Sasanian columns in the southern coast of Asia Minor became easy prey for the reorganized Roman forces led by Callistus/Ballista, who used the greater mobility provided by the Roman navy to surprise the isolated Sasanian columns. According to the IX century CE Byzantine chronicler George Syncellus:
The Persians became dispersed here and there by their greed (for booty). They were on the point of capturing Pompeiopolis on the coast, having laid waste much of Lykaonia, when Callistus (=Ballista) came upon them unawares with ships and a Roman force consisting of men who in their flight had chosen him as their leader. He captured the harem of Shapur with much wealth. Returning with his fleet to Sebaste and Corycus, he wiped out a force of three thousand Persians. Shapur was greatly distressed by this and he withdrew in haste and in fear, and Valerian sojourned among the Persians until the end of his life.
And in another fragment by the XII century CE Byzantine chronicler John Zonaras:
While the situation so favoured the Persians, they spread out over all the east subject to Rome and plundered it without fear. The Romans, however, in their flight appointed as their general one Callistus, so it is said. He saw that the Persians were spread out and attacking the lands without a thought for anyone facing up to them. He launched a sudden attack on them and completed a very great slaughter of the barbarians, and he captured Shapur's concubines together with great wealth. Shapur was greatly pained by this and hastily turned to home, taking Valerian with him. Valerian ended his life in Persia, being reviled and mocked as a prisoner. But Callistus was not the only one then to triumph over the Persians, but also a Palmyrene called Odaenathus made an alliance with the Romans and destroyed many of the Persians. As they retreated, he attacked them along the Euphrates. Gallienus, in return for his generalship, appointed him as dux orientis. Amongst those who fell in the Persian army and were being stripped of their arms there are said to have been found women also, dressed and armed like men, and that such women were also taken alive by the Romans. And during his retreat Shapur came to a deep gorge, through which it was impossible for his baggage animals to pass. He ordered the prisoners to be killed and thrown into the gorge, so that when its depth was filled up with the bodies of the corpses, his baggage animals might make their way across. And in this way he is reported to have crossed the gorge.
Notice again the
topoi of the easterners’ cruelty (the Sasanian king filling the gorge with corpses). In here appears also another factor that precipitated Šābuhr I’s retreat and which was probably much more dangerous than the resistance offered by the Macriani and Callistus: the activities of the
Ras of Palmyra and
vir consularis Septimius Odaenathus. This was the hour of Odaenathus, the moment when he really came to be the ultimate authority in the Roman Near East.
Meanwhile, in the West Gallienus was in a desperate situation. The defense of the East had crumbled again in a most spectacular way and his father had suffered the ultimate humiliation of being captured alive by the Sasanian king. This was an unprecedented blow to Roman prestige, and it obliterated in a moment all the political capital, credibility and goodwill that the Licinian dynasty had accumulated during the previous seven years. An usurpation attempt had already risen in the East under the Macriani, but as the news of the disaster of Edessa travelled west, several other commanders launched their own usurpation attempts all during the very same year of 260 CE. The exact sequence of events is very confused because there’s contradictions in the ancient sources; I will follow here the reconstructed sequence of events proposed by Udo Hartmann and Andreas Golz.
Gallienus had the longest reign of any of the emperors between Caracalla and Diocletian (253-268 CE). This bust is dated at the start of his reign, in it the artist portrayed a serene young man in the elegant and idealized Hellenistic classicizing style which had been typical of imperial portraits since the age of Augustus.
This other bust is dated towards the end of his reign. In it the artist depicted a mature man weighed down by the difficulties and troubles of his reign. Gone is also the Hellenistic style of the previous decade; this portrait announces what will be the Roman art of Late Antiquity, with its departure from the naturalism of the Classical tradition.
As we saw, the capture of Valerian happened probably during the spring or early summer of 260 CE. Last we saw, Gallienus was in Gaul, trying (and failing) to repeal the raids of the Franks and part of the Alamanni. He had his command post in Colonia Agrippina and he had with him his second son Saloninus. But in 260 CE, alarming news reached him: the upper Rhenish-upper Danubian limes had collapsed finally in 259-260 CE after years of sustained pressure by the Alamanni. This catastrophic development must’ve happened either slightly earlier or roughly at the same time as Valerian’s capture. The Alamanni had overrun the Agri Decumates, and together with the Iuthungi (probably a member or a spin-off of the Alamanni confederation, this is the first time that they appear in historical records) they crossed the Alps and entered northern Italy. Their advance was marked by the destruction of the city of Aventicum (modern Avenches) and they probably kept advancing south through the Allgäu in western Switzerland. By the summer of 260 CE, while the Alamanni devastated the north Italian plain, the Iuthungi advanced further south, besieged Ravenna without success and in Rome itself the Senate had to organize an improvised defense with the Urban cohorts, gladiators and armed members of the populace in order to fend off some of the boldest war bands of the Iuthungi. The situation was so alarming that Gallienus had to leave Gaul in a hurry taking part of the army with him and head towards northern Italy. There, he was able to defeat the Alamanni at the battle of Mediolanum that very summer and recover part of the booty and prisoners (it must’ve been an important victory, because the Alamanni stayed quiet for a decade after it), but he was unable to prevent that the Iuthungi crossed the Alpine passes loaded with loot and great numbers of captives to return to their lands. The Iuthungi were intercepted north of the Alps by the army of Raetia supported by the local militia, commanded by the provincial governor
M. Simplicinius Genialis, who by this time had joined an usurpation against Gallienus. This victory was recorded in a votive altar built in the provincial capital of Raetia
Augusta Vindelicorum (modern Augsburg) in which the battle against the Iuthungi is dated to the 24-25 July 260 CE, and in 253it the victorious Romans recorded the recovery of much booty and the liberation of “thousands” of Italian captives.
Reconstruction of Mediolanum (modern Milan) in the IV century CE. Mediolanum was one of the very few cities in the Roman West which grew in the course of the III century CE. Thanks to its strategic position, Gallienus chose it as the main base for his comitatus and as his main residence after Rome. After Gallienus, the city never lost its newly found strategic significance, and under the Tetrarchy it became one of the capitals of the Roman empire.

In the Balkans the general Ingenuus, who had been the tutor of Valerian the Younger and who probably held the command of the whole Danube border was acclaimed as
augustus at an uncertain date; some ancient sources date this revolt to 258 CE, but Hartmann and Golz link it without hesitation to the devastating impact of the news from the East. Probably, the whole Danubian army followed him. Gallienus reacted swiftly and decisively. He couldn’t leave northern Italy due to the Germanic danger and to the alarming new set of events that were happening in Gaul, so Gallienus entrusted part of his army to the cavalry commander Aureolus (who had a brilliant career ahead of him) who defeated Ingenuus decisively at Mursa by the late summer of 260 CE; the usurper was then murdered by his own guardsmen (probably in an attempt to endear themselves to the victors). But in the wake of the end of Ingenuus’ failed revolt, a new usurper arose in the Danube: the senatorial legate of Upper Pannonia
P. C(assius?) Regalianus, who had been probably one of Ingenuus supporters and fearing retribution tried to launch a coup of his own. Once again, Gallienus acted swiftly, and his army, probably with him in command this time defeated Regalianus and besieged him in Sirmium. The revolt was finally crushed by the fall of 260 CE or at the end of this very same year at the latest. Taking advantage of the chaotic situation, the Roxolani Sarmatians and the Germanic Quadi crossed the middle Danube and devastated the Pannonian provinces while the Romans were busy fighting civil wars.

Given the catastrophic situation, Gallienus had deemed too risky to leave Gaul without imperial presence, and so he left his son Saloninus (still a child) at Cologne under the care of a tutor named
Silvanus. As main commander of the Rhine army, he left
Marcus Cassianius Latinius Postumus, who quickly proved himself disloyal to Gallienus. Apparently, Postumus had some success in dealing with the Frankish raiders, and recovered a sizable amount of booty from them, which he then intended to distribute among his men. But then Silvanus (perhaps in a misjudged attempt at establishing his own authority and also that of Saloninus’) ordered Postumus that the booty should be handed over to them. Postumus reacted by addressing his men and telling them that Silvanus and Saloninus wanted to deprive them of the booty that they had legitimately won with their sweat and blood, and the result was inevitable: the soldiers acclaimed Postumus as
augustus and murdered Silvanus and Saloninus. He was acknowledged as such by the provinces in Gaul, Hispania and Britannia as well as Raetia, and proceeded to form a separate “Gallic Empire” that separated from the Roman empire, with its own consuls and magistracies.

But Gallienus’ situation was so desperate that he could not even contemplate avenging his son or recovering the lost western provinces. He had dealt with the Alamanni and two usurpers in the Balkans but there were still the Macriani left, who had formed an army led by Macrianus the Elder and Macrianus the Younger and crossed into Europe with the intention of marching against Italy (Quietus and Callistus remained in the East). The two sons of Macrianus had been raised to the purple in the late summer of 260 CE; the whole East acknowledged them. In Egyptian papyri they’re referred to as
augusti between August 260 CE and October 261 CE (except in Alexandria, where coins were minted again naming Gallienus as
augustus in the summer of 261 CE). By the early summer of 261 CE, the army of the Macriani had reached the Balkans, where parts of the Danubian army which had supported first Ingenuus and later Regalianus joined them. They met in battle against Gallienus’ field army led by Gallienus’ generals Aureolus and Domitianus in a disputed location; ancient sources differ between Illyricum and Pannonia. On the basis of the gravestones of two centurions from Legio VIII Augusta found at Sirmium, Hartmann and Golz propose the environs of
Serdica (modern Sofia in Bulgaria) as the place for the battle. During the battle, most of the army pf the Macriani changed sides, and the two Macriani were either killed during the battle or executed shortly afterwards.
And there was still one more usurpation in the Balkans in this year: a certain
Valens with the surname
Thessalonicus revolted in Macedonia (perhaps he was one of the commanders of the army of the Macriani) as attested by the SHA, the
Epitome de Caesaribus and Ammianus Marcellinus.
Aureolus was the first of a series of brilliant Illyrian commanders of very humble social origins that were promoted by Gallienus and who became the trusted commanders of his
comitatus (the field army that Gallienus based at Mediolanum as a rapid reaction force), grouped together in the elite cavalry unit called
Protectores, which became sort of a select gathering of talented officers; anybody who entered the Protectores could hope to raise to command legions and whole armies in a near future. Other members of this group were the future emperors Claudius Gothicus, Aurelian and probably also Probus, who were all exceptionally gifted generals; these were the men who would change for the better the fortunes of Roman arms.
Under this circumstances, it was impossible for Gallienus to do absolutely anything in the eastern theater, and so he did the only thing that could be done: he appointed Septimius Odaenathus as
dux romanorum (thus appointing him as commander of all the Roman forces in the area) in the late summer of 260 CE. Odaenathus quickly attacked Quietus and Callistus (who had been probably been raised to the rank of Praetorian Prefect by the Macriani), who were besieged in Emesa. The Emesenes finally executed Quietus while Callistus was handed over to Odaenathus, who had him executed in November 261. After this victory, Gallienus appointed Odaenathus as
corrector totius Orientis, an unprecedented title that turned him into the
de facto supreme Roman civilian and military leader in the East (as a sort of viceroy, enjoying perhaps a status similar to the one that Priscus had enjoyed under Philip the Arab). This was obviously a desperate measure, because he was basically handing over command of the Roman East to a foreigner (a Romanized Arab dynast) who had his own base of power independent of Gallienus’ mandate (the kingdom of Palmyra and his control of most Arabian tribes in the Syrian and North Arabian deserts). The emperor knew perfectly well that Odaenathus was the new ultimate authority in the Roman East, and that he was basically
de facto independent from Gallienus; by appointing him as his viceroy Gallienus tried to cover this uncomfortable reality with a veneer of legality (at least Odaenathus seemed to be acting as a Roman official, in the name of Rome and under nominal command of Gallienus
augustus). And luckily for him, he sort of succeeded, at least while Odaenathus was still alive.

But as in the Balkans, this usurpation still dragged for some time: the Praefect of Egypt
L. Mussius Aemilianus had sided with the Macriani, but in the summer of 261 CE he hurried himself back to Gallienus’ side as soon as news of the defeat of the Macriani in the Balkans reached him. But probably fearing reprisals for his disloyalty, he revolted in the winter of 261-262 CE and cut the grain supplies to Rome and to Gallienus’ armies. This was though a minor revolt, as no coins have been found where Aemilianus proclaimed himself as
augustus. By early 262 CE Gallienus sent to Alexandria by sea his general
Aurelius Theodotus (probably yet another Illyrian officer of humble origins, as his name seems to suggest) who by July/September 262 CE appears named in papyri as Praefect of Egypt. According to the ancient sources, Aemilianus was captured alive and sent to Gallienus in Rome, who executed him.
What’s surprising is that in the middle of all this chaos, Odaenathus still found the time and the resources to fight successfully against Šābuhr I, but all Graeco-Roman sources agree that he was very successful in his campaigns against the Sasanian king, although modern scholars are somewhat more skeptical about the alleged magnitude of his victories.
The main point that needs to be made in this respect is that despite the resistance and counterattacks by the Macriani/Callistus and Odaenathus, Šābuhr I still managed to retire back to Ērānšāhr in good order, with his army mostly unscathed, with an enormous booty and the most revealing detail of it all: that he managed to herd back with him thousands of Roman captives on a long journey crossing some difficult terrain (bordering on desert in some cases) with success. The ŠKZ boasts that Šābuhr I carried on mass deportations of Roman captives from
Anērān into his empire, where he settled them in royal lands and even founded several new cities expressly for them. Archaeology is clear in this respect, with clear remains of Roman workmanship in buildings, mosaics and other artifacts in Xuzēstān and Pārs, and this is corroborated not only by western sources but also by eastern ones like the
Chronicle of Seert. A fragment of the lost chronicle of Petrus Patricius is quite revealing about the ease with which the Sasanian army was able to return home bypassing the still existing Roman garrisons in Mesopotamia:
Shapur, the Persian king, crossed the Euphrates with his army [the soldiers] greeted each other and rejoiced that they had escaped the danger which had been repelled. He sent word to the soldiers in Edessa, promising to give them all the Syrian money he had with him, so that they would allow him to pass undisturbed and not choose a venture which would lead them to be subject to attack on both sides and bring him trouble and loss of speed. He said that he did not offer them these things out of fear but because he was eager to celebrate the festival in his own home and he did not want there to be any delay or any hold-up on his journey. The soldiers chose to take the money without risk and to permit him to pass.
The festival that Petrus Patricius is referring to is probably the Iranian New Year (
Nowruz), which usually falls on the spring equinox. This allows us to date the retreat of the Sasanian army to the winter of 260-261 CE, because if Šābuhr I wanted to be in is capital (in Ctesiphon or Bīšāpūr) by the environs of March 21, then he needed to have bypassed Edessa in late January at the very latest (loaded with captives and booty, the army would not have been able to move too quickly). In this context, what Odaenathus fought were probably harassing raids against the slow-moving and vulnerable Sasanian columns. The ancient source which is most exuberant in its praise for Odaenathus’ harassing of the retreating Sasanians is the HA, which is not exactly the most trustful of sources.
Also, the chaotic situation in the Roman empire makes highly plausible that the Romans, who were too busy fighting among themselves, did not bother too much the Sasanian army during its retreat.
But another thing altogether is that these sources all agree that later Odaenathus fought a campaign against the Sasanians in Mesopotamia with considerable success, and that this was probably the first victorious “Roman” counterattack against the Sasanian empire in a long time. By 262 CE, the situation within the empire had become somewhat more stabilized compared to what it was two years before. Now, the “only” problems were:
- The secessionist Empire of Gaul led by Postumus.
- A revolt by Memor, commander of the Moorish cavalry troops quartered in Egypt which was quickly suppressed by Gallienus’ governor Theodatus.
- A major wave of social unrest in Sicily (a major slaves’ revolt, mass flight of the lands, and the formation of large gatherings of “brigands”).
- A mutiny of the garrison of the strategic city of Byzantium in the summer of 262 CE, which had to be suppressed by Gallienus himself.
- Another major Gothic invasion, according to the HA and the Getica, in which a large Gothic army led by the duces Gothorum Respa, Veduco and Thaurano crossed the lower Danube and marched across Lower Moesia and Thrace undisturbed, crossed the Straits on ships that had followed their path along the Black Sea coast and invaded Bithynia and Asia. The ease with which they were able to do this was probably connected to the mutiny of the Byzantium garrison. In the rich provinces of Bithynia and Asia, they looted and destroyed among many other towns and cities the major urban centers of Chalcedon, Ilium, Nicomedia and Ephesus, the largest and richest city in the whole province of Asia (and probably in the whole of Anatolia as well), where the Goths destroyed the great temple of Artemis, the Artemision, one of the wonders of the ancient world. Later the Goths dispersed into smaller war bands who raided deep inland into Lydia, Phrygia, Galatia and Cappadocia. And then the Goths could return home completely undisturbed following the very same route they’d used to invade the empire, taking with them an immense booty and large numbers of captives, amongst whom (according to the ecclesiastical historian Philostorgius) were many Christians, including the forebears of Wulfilas, who would be the apostle of the Goths in the IV century CE.
Apart from these "minor troubles", all was quiet and calm, and so Odaenathus organized a large-scale attack against Sasanian territory, and in 262 CE he invaded Sasanian-held northern Mesopotamia and retook Nisibis (it's unclear if he really took it, and if managed to do it, if he was able to keep it), after which he turned south and invaded central Mesopotamia during the winter of 262-263 CE, managing to reach Ctesiphon and putting it under siege. The siege was unsuccessful, and by the summer of 263 CE he was back in Syria, where to add insult to injury he took the title
rex regum, a direct insult to Šābuhr I. In the second half of 263 CE, Gallienus took the credit for “his general’s” victory, adopted the title
Persicus Maximus and celebrated a formal triumph in Rome. But now Odaenathus was in the zenith of his ascendancy, and began to slip steadily from under Gallienus’ influence, which forecasted trouble for the future. Odaenathus’ attack during the autumn and winter must’ve been deftly planned in order to take Šābuhr I and his royal forces in Mesopotamia and Xuzēstān isolated from reinforcements from the Iranian plateau, exploiting one of the key weaknesses of the early Sasanian military system, the seasonality of its armies.

Šābuhr I died in 270 CE in Bīšāpūr in Pārs after ruling for 30 years as king of kings of the Iranians and non-Iranians. If we take into account that in the great victory relief of Ardaxšir I at Ardaxšir-Xwarrah he appears as a grown man, and that at the investiture relief of Ardaxšir I at Naqš-e Rajab he appears already with his eldest son Bahrām I as a small child, he must’ve been 18-20 years old at the time. By 260 CE, Šābuhr I must’ve been about 60 years old and probably not in a good enough physical condition to keep leading his armies in person as he’d always done. After his return from his last invasion in 260 CE and the invasion of Odaenathus, the almost frantic pace of Sasanian aggression against the Roman empire that had characterized eastern politics since the accession of Ardaxšir I ceased completely, which was an immense relief for Rome. The Sasanians had been instrumental in bringing Rome down to its darkest decade in 260-270 CE (perhaps they’d been the most important amongst the external factors that brought Rome to the brink of the abyss), but now that Rome was struggling to survive, the Sasanians just disappeared from the scene. During this last decade of his reign, apart from fighting against the “Odaenathus’ scare”, the only activities that can be reconstructed for Šābuhr I in the historical record is the carving of his great propagandistic rock reliefs and inscriptions and the building of his town and palace at Bīšāpūr. It’s almost as if the old king spent his last ten years reliving his past glories and making sure that they were recorded for posterity.
Šābuhr I has deservedly gone down in history as Šābuhr I the Great. In the picture, his colossal statue (6.70 meters tall) in the so-called "cave Šābuhr", located 6 km from Bīšāpūr in Pārs.
It’s difficult to explain this sudden eclipse of the Sasanians, but I’d venture and say that it was a combination of factors. First of all, the most important factor was a biological one: by now Šābuhr I was an old man, and so he was just unable to sustain the same degree of activity that he’d done since he was his father’s appointed successor. Another factor could be that simply put Šābuhr I felt that the objectives that he and his father had set up for themselves in the West had been attained: the Sasanians were now in firm control of Armenia and most of northern Mesopotamia, which together formed a defensive barrier against Roman attacks into the Iranian plateau, and equally important the Arsacids had been expelled from Armenia. This second factor though depends upon the consideration (which is nowadays the consensus amongst scholars) that the supposed goals of Ardaxšir I as stated by Dio Cassius and Herodian (the restoration of the Achaemenid empire) were merely a bluff in front of the Roman emperor Severus Alexander. This also implies that on the whole the Sasanian policy in the West against Rome had been altogether mainly a defensive one: Ardaxšir I and his son had sought only to secure a “cordon sanitaire” against Rome and to remove the danger that the Arsacids of Armenia represented for the internal stability of the new Sasanian regime in Iran. This would agree with the relative restraint by these two Sasanian kings in their annexations in the West, compared with the sweeping conquests that they made in the East.
And finally another factor could be a certain level of exhaustion: by 260 CE, the war against Rome had dragged on almost without cease (except for the 244-252 CE time frame) since 230 CE, and one key weakness of the ancient Iranian empires was the scarcity of their military manpower. Not only was Iran sparsely populated compared to the Roman Empire, but most importantly the Sasanians (as the Arsacids) depended to a disproportionate degree for their military successes on the small group of elite fighters represented by the Iranian nobility. Due to the Iranian social structure, this was a small, closed group which could only replenish its losses through generational replacement (although the kings could elevate commoners into the nobility, there are not many examples known of that, and given the attitudes and mores of the Iranian nobility, if the kings used this expedient on a massive scale, this would have caused serious trouble). Although the first two Sasanian kings had inflicted devastating defeats to Rome and had been a decisive factor in plunging their western foe into their deepest crisis in history, in the long run demographic and economic realities could not be ignored. And probably from an Iranian point of view, Rome in the decade of the 260s had ceased to be any serious danger, due to the internal chaos of the empire and the ongoing waves of invasions it was suffering from the mouths of the Rhine to the mouths of the Danube.
