According to Hermippus, his death took place at Pisa, just after he had congratulated his son on an Olympic victory in boxing. It was due to excess of joy coupled with the weakness of a man stricken in years.
Ἐτελεύτησε δʼ, ὥς φησιν Ἕρμιππος, ἐν Πίσῃ, τὸν υἱὸν Ὀλυμπιονίκην ἀσπασάμενος πυγμῆς. ἔπαθε δὲ τοῦτο ὑπερβολῇ τε χαρᾶς καὶ ἀσθενείᾳ πολυετίας.
