Passage 9.10.1
πολυάνδριον δὲ οὐ μακρὰν ἀπὸ τῶν πυλῶν ἐστι· κεῖνται δὲ ὁπόσους κατέλαβεν ἀποθανεῖν Ἀλεξάνδρῳ καὶ Μακεδόσιν ἀντιτεταγμένους. οὐ πόρρω δὲ ἀποφαίνουσι χωρίον ἔνθα Κάδμον λέγουσιν--- ὅτῳ πιστά---τοῦ δράκοντος, ὃν ἀπέκτεινεν ἐπὶ τῇ κρήνῃ, τοὺς ὀδόντας σπείραντα, ἄνδρας δὲ ἀπὸ τῶν ὀδόντων ἀνεῖναι τὴν γῆν.
Not far from the gates is a common grave, where lie those who happened to fall fighting against Alexander and the Macedonians. Nearby they point out the place where, according to the story about Cadmus—whoever believes it—he killed the dragon at the spring and sowed its teeth, from which men sprang up from the earth.
