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 18, 19, 20, and 21, written in 404, are recommendations for an important man from Alexandria. In Letter 20, he is called Ammonius. They are offered here in the translation by A. Fitzgerald.
Letter 19: A Recommendation
 To Herodes and Martyriusnote[Herodes was an officer and a relative of Synesius, mentioned in Letter 38; Martyrius is otherwise unknown.]
In writing a letter to you in common, I consider that I am in no way at fault. Rather would it have been a just reproach to me if I had divided in my letters those who are united in my heart. Accept all my best wishes, my dear friends, and to the man who is delivering the letter to you, who has journeyed on the public highway to convey gold to you, extend the warmest possible welcome, for he has been recommended to me by the entire senate.note[The town council of Alexandria is meant.]
 I should like to be of some use to him. In fact, I do not know that others should care more for us and for the things we may undertake than you do.
