Philogelos 9b:
A scholar, wishing to teach his horse not to eat so much, stopped giving it food. Later, when the horse died of hunger, the scholar said, “Ah, I’ve suffered a great loss! Just when he learned not to eat, he died!”
β: Σχολαστικὸς θέλων τὸν ἵππον αὐτοῦ διδάξαι μὴ τρώ-
γειν πολλὰ οὐ παρέβαλλεν αὐτῷ τροφάς. ἀποθανόντος δὲ τοῦ
ἵππου τῷ λιμῷ ἔλεγε· Μεγάλως ἐζημιώθην· ὅτε γὰρ καλῶς
ἔμαθε μὴ τρώγειν, τότε ἀπέθανεν.
