Unto His Grace, Gerardindo da Lucari, Duke of Siena and Count of Cortona,
FROM
Roman Emperor John, Equal to the Apostles, Ruler of Time and of Space,
Verily, Duke Gerardindo, I am pleased to recieve your letter in which you acknowledge my rights as the Roman Emperor. Such courtesy and sense is, I have found, not often encountered among Italians. Indeed, I am engaged in a struggle with the Turk, who spreads across these lands like the Great Mortality, devouring all in their path. However, unlike the pestilence, this plague can be countered and stopped by mere mortals, with the help of God.
However, my good Duke, you are quite mistaken. I personally acknowledge the Roman Patriarch and its rites, although I have taken no steps to force this upon my subjects. I am a practitioner of 'Romanism' as you are, and attend Latin mass daily. But yet, I also thank you for your desire to unite both Rome and New Rome against the barbarian hordes that even now subjugate good Christians, both Latin and Greek.
You write, Duke Gerardindo, of your desire to fight the Turk. I wish to offer you this chance. Even now, I am assembling a vast army to combat the Turk, and drive them from Europe. Our cousin, the King of Mallorca, has already pledged himself to doing so, as has the Dowager Queen of Hungary and the King of Sicily. You are known as a man of valor and action, and would prove a worthy addition to this grand army. I therefore invite you and your men to Constantinople, from where we shall set out to defeat the Turk and end their menace once and for all.
Perhaps, Duke Gerardindo, as you look eastward in pursuit of glory and honor, you could also look for a wife. I have four daughters, all young maidens with their virtue intact. If you were to fight under my banner, I would award you with a prize worthy of a prince.
-Emperor John
