Passage 8.44.3
τοῦ Ἀθηναίου δὲ μάλιστα εἴκοσιν ἀπωτέρω σταδίοις ἐρείπια Ἀσέας ἐστί, καὶ ὁ λόφος ἀκρόπολις τότε οὖσα τείχους σημεῖα ἔχει καὶ ἐς τόδε. σταδίους δὲ ὅσον πέντε ἀπὸ Ἀσέας τοῦ Ἀλφειοῦ μὲν ὀλίγον ἄπο τῆς ὁδοῦ, τοῦ δὲ Εὐρώτα παρʼ αὐτήν ἐστιν ἡ πηγὴ τὴν ὁδόν· πρός τε τοῦ Ἀλφειοῦ τῇ πηγῇ ναός τε Μητρὸς θεῶν ἐστιν οὐκ ἔχων ὄροφον καὶ λέοντες λίθου δύο πεποιημένοι.
About twenty stades farther from Athenaion lie the ruins of Asea; the hill, formerly its acropolis, still bears traces of its walls to this day. About five stades from Asea, a little distance off the road, lies the source of the Alpheios, whereas the source of the Eurotas is beside the road itself. Near the source of the Alpheios stands a sanctuary of the Mother of the Gods, roofless, and there are two stone lions.
