Passage 2.9.6
μετὰ δὲ τὸ Ἀράτου ἡρῷον ἔστι μὲν Ποσειδῶνι Ἰσθμίῳ βωμός, ἔστι δὲ Ζεὺς Μειλίχιος καὶ Ἄρτεμις ὀνομαζομένη Πατρῴα, σὺν τέχνῃ πεποιημένα οὐδεμιᾷ· πυραμίδι δὲ ὁ Μειλίχιος, ἡ δὲ κίονί ἐστιν εἰκασμένη. ἐνταῦθα καὶ βουλευτήριόν σφισι πεποίηται καὶ στοὰ καλουμένη Κλεισθένειος ἀπὸ τοῦ οἰκοδομήσαντος· ᾠκοδόμησε δὲ ἀπὸ λαφύρων ὁ Κλεισθένης αὐτὴν τὸν πρὸς Κίρρᾳ πόλεμον συμπολεμήσας Ἀμφικτύοσι. τῆς δὲ ἀγορᾶς ἐστιν ἐν τῷ ὑπαίθρῳ Ζεὺς χαλκοῦς, τέχνη Λυσίππου , παρὰ δὲ αὐτὸν Ἄρτεμις ἐπίχρυσος.
Beyond the hero-shrine of Aratus there is an altar dedicated to Poseidon Isthmius, as well as (shrines of) Zeus Meilichios and Artemis called Patroia ("Ancestral"), neither of which has been fashioned with any artistic skill. Zeus Meilichios is represented by a pyramid, while Artemis takes the form of a column. Here also stands their council chamber and a stoa called Cleistheneios, named after Cleisthenes who built it. Cleisthenes erected it from the spoils taken when he fought alongside the Amphictyons in the war against Cirrha. In the marketplace, in the open air, there is a bronze statue of Zeus, a work by Lysippos, and beside him stands a gilded Artemis.
