Passage 2.12.2
ἐκ δὲ Τιτάνης ἐς Σικυῶνα ἀφικομένοις καὶ καταβαίνουσιν ἐς θάλασσαν ἐν ἀριστερᾷ τῆς ὁδοῦ ναός ἐστιν Ἥρας οὐκ ἔχων ἔτι οὔτε ἄγαλμα οὔτε ὄροφον· τὸν δὲ ἀναθέντα Προῖτον εἶναι τὸν Ἄβαντός φασι. καταβᾶσι δὲ ἐς τὸν Σικυωνίων καλούμενον λιμένα καὶ τραπεῖσιν ἐπʼ Ἀριστοναύτας τὸ ἐπίνειον τὸ Πελληνέων, ἔστιν ὀλίγον ὑπὲρ τὴν ὁδὸν ἐν ἀριστερᾷ Ποσειδῶνος ἱερόν· προελθοῦσι δὲ κατὰ τὴν λεωφόρον Ἑλισσών τε καλούμενος ποταμὸς καὶ μετʼ αὐτὸν Σύθας ἐστίν, ἐκδιδόντες ἐς θάλασσαν.
On the road from Titane to Sicyon, as one heads downhill towards the sea, there is, on the left side of the way, a temple of Hera, now lacking both its statue and its roof. The dedicant of this temple is said to have been Proetus, the son of Abas. When one has descended to the harbor of the Sicyonians, as it is called, and turned towards Aristonautae, the harbor of the Pellenians, there stands a shrine of Poseidon a little above the road, on the left. Continuing further along the main road, one comes to a river called the Elisson, followed by another called the Sythas, both of which flow into the sea.
