Passage 7.17.1
ἐς ἅπαν δὲ ἀσθενείας τότε μάλιστα κατῆλθεν ἡ Ἑλλάς, λυμανθεῖσα κατὰ μέρη καὶ διαπορθηθεῖσα ἐξ ἀρχῆς ὑπὸ τοῦ δαίμονος. Ἄργος μέν, ἐς πλεῖστον ἀφικομένην δυνάμεως πόλιν ἐπὶ τῶν καλουμένων ἡρώων, ὁμοῦ τῇ μεταβολῇ τῇ ἐς Δωριέας ἐπέλιπε τὸ ἐκ τῆς τύχης εὐμενές·
Hellas then reached the utmost weakness, devastated region by region and thoroughly wasted from its earliest state by the divinity. As for Argos, a city that had attained the greatest power in the age of the so-called heroes, at the same time of the change to the Dorians, its previous good fortune deserted it.
