Passage 7.25.4
ἐγένετο δὲ τῆς Ἑλίκης ἀπώλεια Ἀστείου μὲν Ἀθήνῃσιν ἔτι ἄρχοντος, τετάρτῳ δὲ ἔτει τῆς πρώτης Ὀλυμπιάδος ἐπὶ ταῖς ἑκατόν, ἣν Δάμων Θούριος ἐνίκα τὸ πρῶτον. Ἑλικαέων δὲ οὐκέτι ὄντων νέμονται τὴν χώραν οἱ Αἰγιεῖς.
The destruction of Helice took place when Asteius was still archon at Athens, in the fourth year of the hundred and first Olympiad, in which Damon of Thurii won for the first time. Since the inhabitants of Helice no longer existed, the Aegians occupied their territory.
