Synesius, Letter 119
Synesius of Cyrene (c.370-c.413) was a Neo-Platonic philosopher who became bishop of Ptolemais in the Cyrenaica. He left behind a small corpus of texts that offer much information about daily life in Late Antiquity, and about the christianization of the Roman world.
Letters 118, 119, and 131 can be dated to c.406 and are offered here in the translation by A. Fitzgerald. The lawsuit is explained in Letter 131; the addressee is not known from other sources.
Letter 119: A Recommendation
 To Trypho
Whatever you did for Diogenes, of all that it is in your nature to accomplish, you will have done nothing new, but will be adding another deed to those already achieved by you. He is from Cyrene, and that city owes its continued existence to you.note[A reference to the siege of Cyrene in the preceding year.] But you must benefit the citizens not only collectively but also individually.
 As to the matter in which Diogenes is implicated, and for which he stands in need of friends to come to his aid, he will tell you all about this in conversation much better than I could do in writing, for nothing could be more eloquent than the man who has suffered.
 Salute Marcian the philosopher for me; I mean the ex-governor of Paphlagonia. If he can do anything, and I fancy he can, I beg him to prevent my relative, my very own cousin, from becoming the victim of calumniating informers, who are the curse of the whole country.
 I commend him to your care with this letter. Treat him like a son, for if we are only two brothers by blood, Euoptius and I, nevertheless, with Diogenes, we become three by the links of affection.
