Suda, s.v. Pythagoras of Ephesos

“Pythagoras of Ephesos. Once he overthrew the government called the reign of the Basilidai, Pythagoras became the harshest tyrant. He seemed and sometimes was very kind to the people and the masses, increasing their hopes, but under-delivering on their profits. Because he despoiled those in high esteem and power and liquidated their property, he was not at all tolerable.

He did not hesitate to impose the harshest punishments or to mercilessly kill those who had done no wrong—for he had gotten just this crazy. His lust for money was endless. He was also quickest to anger in response to any insults to those near to him. On their own, these things would have been enough reason for people to kill him in the worst way, but he also was contemptuous of the divine. Indeed, many of his previously mentioned victims he actually killed in temples.

When the daughters of one man took refuge in a temple, he did not dare to extract them forcefully, but he waited them out so long that the girls resolved their hunger with a rope. A plague then afflicted the people along with a famine and Pythagoras, who was worried for himself, sent representatives to Delphi, requesting relief from these sufferings. She said that he needed to build temples and take care of the dead. He lived before Cyrus of Persia, according to Batôn.”

Πυθαγόρας ᾽Εφέσιος· καταλύσας δι᾽ ἐπιβουλῆς τὴν τῶν Βασιλιδῶν καλουμένην ἀρχήν, ἀνεφάνη τε τύραννος πικρότατος. καὶ τῶι μὲν δήμωι καὶ τῆι πληθύι ἦν τε καὶ ἐδόκει κεχαρισμένος, ἅμα τὰ μὲν αὐτοὺς ἐπελπίζων ὑποσχέσεσιν, τὰ δὲ ὑποσπείρων αὐτοῖς ὀλίγα κέρδη· τούς γε μὴν ἐν ἀξιώσει τε καὶ δυνάμει περισυλῶν καὶ δημεύων φορητὸς οὐδαμὰ οὐδαμῆ ἦν. καὶ κολάσαι δὲ πικρότατα οὐκ ἂν ὤκνησε, καὶ ἀφειδέστατα ἀποκτεῖναι οὐδὲν ἀδικοῦντας (ἐξελύττησε γὰρ εἰς ταῦτα)· ἔρως τε χρημάτων ἄμετρος· καὶ διαβολαῖς ταῖς ἐς τοὺς πλησίους ἐκριπισθῆναι κουφότατος ἦν. ἀπέχρησε μὲν οὖν καὶ ταῦτα ἂν κάκιστα ἀνθρώπων ἀπολέσαι αὐτόν, ἤδη δὲ καὶ τοῦ θείου κατεφρόνει· τῶν γοῦν προειρημένων οἷς ἐπέθετο παμπόλλους ἐν τοῖς ναοῖς ἀπέκτεινεν, ἑνὸς δὲ τὰς θυγατέρας καταφυγούσας εἰς τὸ ἱερὸν ἀναστῆσαι μὲν βιαίως οὐκ ἐτόλμησε, συνεχῆ δὲ φυλακὴν ἐπιστήσας ἐξετρύχωσεν ἄρα ἐς τοσοῦτον, ὡς βρόχωι τὰς κόρας τὸν λιμὸν ἀποδρᾶναι. οὐκοῦν ἠκολούθησε δημοσίαι νόσος καὶ τροφῶν ἀπορία· καὶ σαλεύων ὑπὲρ ἑαυτοῦ ὁ Πυθαγόρας εἰς Δελφοὺς ἀπέστειλε καὶ ἤιτει λύσιν τῶν κακῶν. ἡ δὲ ἕφη νεὼν ἀναστῆσαι καὶ κηδεῦσαι τοὺς νεκρούς. ἦν δὲ πρὸ Κύρου τοῦ Πέρσου, ὥς φησι Βάτων.
