Passage 3.22.4
προελθόντι που σταδίους ἐπὶ θαλάσσης πόλις ἐστὶν Ἀκρίαι· θέας δὲ αὐτόθι ἄξια Μητρὸς θεῶν ναὸς καὶ ἄγαλμα λίθου. παλαιότατον δὲ τοῦτο εἶναί φασιν οἱ τὰς Ἀκρίας ἔχοντες, ὁπόσα τῆς θεοῦ ταύτης Πελοποννησίοις ἱερά ἐστιν, ἐπεὶ Μαγνησί γε, οἳ τὰ πρὸς Βορρᾶν νέμονται τοῦ Σιπύλου, τούτοις ἐπὶ Κοδδίνου πέτρᾳ Μητρός ἐστι θεῶν ἀρχαιότατον ἁπάντων ἄγαλμα· ποιῆσαι δὲ οἱ Μάγνητες αὐτὸ Βροτέαν λέγουσι τὸν Ταντάλου.
Advancing roughly four stades toward the sea, there is a city called Akriai. Things worthy of seeing there include a temple of the Mother of the Gods, and an image fashioned from stone. Those who inhabit Akriai assert that this sanctuary is the oldest among all the shrines dedicated to the goddess in the Peloponnese. However, among the Magnesians, who dwell to the north of Mount Sipylos, there is the most ancient image of the Mother of the Gods placed upon the rock called Koddinos. The Magnesians claim that Broteas, son of Tantalus, fashioned this image.
