§6.3.1Ἑλλήνων δὲ πρῶτοι Χαλκιδῆς ἐξ Εὐβοίας πλεύσαντες μετὰ Θουκλέους οἰκιστοῦ Νάξον ᾤκισαν, καὶ Ἀπόλλωνος Ἀρχηγέτου βωμὸν ὅστις νῦν ἔξω τῆς πόλεώς ἐστιν ἱδρύσαντο, ἐφ’ ᾧ, ὅταν ἐκ Σικελίας θεωροὶ πλέωσι, πρῶτον θύουσιν. §6.3.2Συρακούσας δὲ τοῦ ἐχομένου ἔτους Ἀρχίας τῶν Ἡρακλειδῶν ἐκ Κορίνθου ᾤκισε, Σικελοὺς ἐξελάσας πρῶτον ἐκ τῆς νήσου ἐν ᾗ νῦν οὐκέτι περικλυζομένῃ ἡ πόλις ἡ ἐντός ἐστιν· ὕστερον δὲ χρόνῳ καὶ ἡ ἔξω προστειχισθεῖσα πολυάνθρωπος ἐγένετο. §6.3.3Θουκλῆς δὲ καὶ οἱ Χαλκιδῆς ἐκ Νάξου ὁρμηθέντες ἔτει πέμπτῳ μετὰ Συρακούσας οἰκισθείσας Λεοντίνους τε πολέμῳ τοὺς Σικελοὺς ἐξελάσαντες οἰκίζουσι, καὶ μετ’ αὐτοὺς Κατάνην· οἰκιστὴν δὲ αὐτοὶ Καταναῖοι ἐποιήσαντο Εὔαρχον.
Of the Greeks, the first to sail from Euboea were the Chalcidians, who, under the leadership of Thucles as founder, founded Naxos, and established the altar of Apollo Archegetes (the Founder), which is now outside the city, and on which, whenever sacred envoys sail from Sicily, they first offer sacrifice.\n In the following year, Archias, one of the Heracleidae, from Corinth, founded Syracuse, having first expelled the Sicels from the island, within which the inner city now stands, although it is no longer surrounded by water; and in later times the outer city also, being enclosed by an additional wall, became populous.\n Thucles and the Chalcidians, setting out from Naxos in the fifth year after the founding of Syracuse, founded Leontini, having expelled the Sicels by war, and after them, Catana; but the Catanaeans themselves chose Euarchus as their founder.
