Eunapius Lives of the Sophists, 494
Diophantos was also from Arabia and he pushed his way among the teachers of the craft of rhetoric. The same jealous belief of humankind established that man as competitor with Prohairesios, as if someone would make Callimachus Homer’s rival! But Prohairesious just laughed these things off along with human beings and whatever things occupied them. The writer of this work knew Diphantos and heard him speaking in public frequently. But it did not seem right to quote in this work anything which was said or which was mentioned by him—for this is a memoir of men worthy of account, not satire.
Nevertheless, people report that he gave a funeral speech for Prohairesios—since that man died before he did—and they record that he uttered something of this kind about Salamis and the Medes: “O Marathon and Salamis, now you are silenced! What kind of a trumpet of your trophies have you lost!” He left behind him two sons who were devoted to luxury and wealth.”
Καὶ Διόφαντος ἦν μὲν ἐξ Ἀραβίας, καὶ εἰς τοὺς τεχνικοὺς ἐβιάζετο· ἡ δὲ αὐτὴ δόξα τῶν ἀνθρώπων Προαιρεσίῳ κἀκεῖνον ἀντήγειρεν, ὡσεὶ Καλλίμαχον Ὁμήρῳ τις ἀναστήσειεν. ἀλλ᾿ ἐγέλα ταῦτα ὁ Προαιρέσιος, καὶ τοὺς ἀνθρώπους ὅ τι εἰσὶν ἐν διατριβῆς εἶχεν μέρει. τοῦτον ἐγίγνωσκεν ὁ συγγραφεύς, καὶ ἠκροάσατό γε πολλάκις δημοσίᾳ λέγοντος. παραθεῖναι δὲ τῇ γραφῇ τῶν λεχθέντων καὶ μνημονευθέντων οὐδὲν ἐδόκει καλῶς ἔχειν· μνήμη γάρ ἐστιν ἀξιολόγων ἀνδρῶν, οὐ χλευασμός, ἡ γραφή. ἀλλ᾿ ὅμως ἐπιτάφιόν γε εἰπεῖν τινα τοῦ Προαιρεσίου λέγεται (προαπῆλθε γὰρ ὁ Προαιρέσιος), καί τι τοιοῦτον ἐπιφθέγξασθαι διαμνημονεύουσιν ἐπὶ τῇ Σαλαμῖνι καὶ τοῖς Μηδικοῖς· “ὦ Μαραθὼν καὶ Σαλαμίν, νῦν σεσίγησθε. οἵαν σάλπιγγα τῶν ὑμετέρων τροπαίων ἀπολωλέκατε.” οὗτος ἀπέλιπε δύο παῖδας ἐπὶ τρυφὴν καὶ πλοῦτον ὁρμήσαντας.
