Suiones is for the origin of the Svea-rige/Sverige(sweden on english) as Dani is for Danes.
If not for the swedes winning over the goths sweden might be named Gøtaland instead.
Svea Yellow, Gøtar Blue. Mediveal times.
Even the "mighty" Suebi have mostly a description on their hair:
"We must now speak of the Suebi, who do not, like the Chatti or the Tencteri, constitute a single nation. They occupy more than half Germany, and are divided into a number of separate tribes under different names, though all are called by the generic title of 'Suebi'. It is a special characteristic of this nation to comb the hair sideways and tie it in a knot. This distinguishes the Suebi from the rest of the Germans, and, among the Suebi, distinguishes the freeman from the slave. Individual men of other tribes adopt the same fashion, either because they are related in some way to the Suebi, or merely because the imitative instinct is so strong in human beings; but even these few abandon it when they are no longer young. The Suebi keep it up till they are gray- headed; the hair is twisted back so that it stands erect, and is often knotted on the very crown of the head. The chiefs use an even more elaborate style. But this concern about their personal appearance is altogether innocent. These are no lovelocks to entice women to accept their advances. Their elaborate coiffure is intended to give them greater height, so as to look more terrifying to their foes when they are about to go into battle."
The "mighty" Marcomenni also have quite an small description:
"Close behind the Marcomanni and Quadi are the Marsigni, Cotini, Osi, and Buri. Of these, the Marsigni and Buri are exactly like the Suebi in language and mode of life. The Cotini and the Osi are not Germans: that is proved by their languages, Celtic in the one case, Pannonian in the other, and also by the fact that they submit to paying tribute. "
Famus Cherusci seem a bit broken:
"On the flank of the Chauci and the Chatti, the Cherusci have been left free from attack to enjoy a prolonged peace, too secure and enervating - a pleasant but perilous indulgence among powerful aggressors, where there can be no true peace. When force decides everything, forbearance and righteousness are qualities attributed only to the strong; and so the Cherusci, once known as 'good, honest people', now hear themselves called lazy fools, while the luck of the victorious Chatti passes for profound wisdom. The fall of the Cherusci involved also the neighbouring tribe of the Fosi, who played second fiddle to them in prosperity but get an equal share of their adversity."
Cimbri, from scandinavia far from roman borders offcorse we know migrated south:
"In the same corner of Germany, nearest to the open sea, dwell the Cimbri, a name mighty in history, though now they are only a little state. Widespread traces of their ancient fame may still be seen: huge encampments on both sides of the Rhine, by their enormous circuit, still give a measure of the mass and man-power of the nation and demonstrate the historical truth of that great exodus."
Further mentions:
"The Angrivarii and Chamavi have a common frontier on one side with the Dulgubnii, Chasuarii, and other tribes of no special fame, while on the north-west they are succeeded by the Frisii, who comprise a larger section and a smaller section, called respectively the Greater and the Lesser Frisii. Both sections have the Rhine as a frontier right down to the Ocean, and their settlements also extend round vast lagoons, which have been sailed by Roman fleets. We have even ventured upon the Northern Ocean itself, and rumour has it that there are Pillars of Hercules in the far north. It may be that Hercules did go there; or perhaps it is only that we by common consent ascribe any remarkable achievement in any place to his famous name. Drusus Germanicus did not lack the courage of the explorer, but Ocean forbade further research into its own secrets or those of Hercules. Since then no one has attempted it. It has been judged more pious and reverent to believe in the alleged exploits of gods than to establish the true facts."
Can go on but i find the swedes mentioned no weaker than other germanic tribes.
