Plutarch, Parallel Stories, 29
“Aristonomos the son of Demostratos hated women and used to have sex with a donkey. After some time, the donkey gave birth to an extremely beautiful girl named Onoskelis. Aristokles reports this in the second book of his Unbelievable Things.
Fulvius Stellus used to have sex with a horse because he hated women. Eventually the horse gave birth to a fine-looking girl and they named her Epona. She is a deity who focuses on horses. This is according to Agesilaus in the third book of his Italian Matters.”
- ΑΡΙΣΤΩΝΥΜΟΣ Ἐφέσιος υἱὸς Δημοστράτου ἐμίσει γυναῖκας, ὄνῳ δ᾿ ἐμίσγετο· ἡ δὲ κατὰ χρόνον ἔτεκε κόρην εὐειδεστάτην Ὀνόσκελιν τοὔνομα· ὡς Ἀριστοκλῆς ἐν δευτέρᾳ Παραδόξων.
EΦΟΥΛΟΥΙΟΣ Στέλλος μισῶν γυναῖκας ἵππῳ συνεμίσγετο· ἡ δὲ κατὰ χρόνον ἔτεκε κόρην εὔμορφον καὶ ὠνόμασαν Ἔποναν· ἔστι δὲ θεὸς πρόνοιαν ποιουμένη ἵππων· ὡς Ἀγησίλαος ἐν τρίτῳ Ἰταλικῶν.
That has to be one of the strangest things I’ve read.
