Name:   Phlegon of Tralles Date:     2nd century CE Region: Tralles [modern Turkey] Citation:    On Marvels 5

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

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.
