Passage 1.44.10
προελθοῦσι δὲ ἐς τὸ πρόσω μνῆμά ἐστιν Εὐρυσθέως· φεύγοντα δὲ ἐκ τῆς Ἀττικῆς μετὰ τὴν πρὸς Ἡρακλείδας μάχην ἐνταῦθα ἀποθανεῖν αὐτὸν ὑπὸ Ἰολάου λέγουσιν. ἐκ ταύτης τῆς ὁδοῦ καταβᾶσιν Ἀπόλλωνος ἱερόν ἐστι Λατῴου καὶ μετʼ αὐτὸ Μεγαρεῦσιν ὅροι πρὸς τὴν Κορινθίαν, ἔνθα Ὕλλον τὸν Ἡρακλέους μονομαχῆσαι πρὸς τὸν Ἀρκάδα Ἔχεμον λέγουσιν.
Going forward along the road there is the tomb of Eurystheus. They say that, fleeing from Attica after the battle against the Heracleidae, he was killed here by Iolaus. Descending from this route is a sanctuary of Apollo Latoios; just beyond it are the boundaries of Megara with Corinth, where they say Hyllus, son of Heracles, fought a duel against the Arcadian Echemus.
