A Trans Man: Caeneus, Phlegon of Tralles' De Mira. V

Iidem perhibent, apud Lapithas Elato regi filiam fuisse, nomine Caenidem. Cum hac Neptunum congressum, promisisse, facturum se ei quodcumque vellet: ipsam petiisse, ut ab eo in virum mutaretur, fieretque invulnerabiis; praestitisse id Neptunum, nomenque viro Caenaeus factum.

--Phlegon of Tralles, de Mirabilibus V; Translated into Latin by Wilhelm Xylander 

They say that Caenis was the daughter of the Lapith king Elatus. When she “met” Neptune, he promised that he would grant her whatever she wanted: and she asked to be turned into a man, as well as become invincible. Neptune granted his wish, and the man’s name became Caenaeus.
