Passage 1.26.5
---ἔστι δὲ καὶ οἴκημα Ἐρέχθειον καλούμενον· πρὸ δὲ τῆς ἐσόδου Διός ἐστι βωμὸς Ὑπάτου, ἔνθα ἔμψυχον θύουσιν οὐδέν, πέμματα δὲ θέντες οὐδὲν ἔτι οἴνῳ χρήσασθαι νομίζουσιν. ἐσελθοῦσι δέ εἰσι βωμοί, Ποσειδῶνος, ἐφʼ οὗ καὶ Ἐρεχθεῖ θύουσιν ἔκ του μαντεύματος, καὶ ἥρωος Βούτου, τρίτος δὲ Ἡφαίστου· γραφαὶ δὲ ἐπὶ τῶν τοίχων τοῦ γένους εἰσὶ τοῦ Βαυταδῶν καὶ---διπλοῦν γάρ ἐστι τὸ οἴκημα--- καὶ ὕδωρ ἐστὶν ἔνδον θαλάσσιον ἐν φρέατι. τοῦτο μὲν θαῦμα οὐ μέγα· καὶ γὰρ ὅσοι μεσόγαιαν οἰκοῦσιν, ἄλλοις τε ἔστι καὶ Καρσὶν Ἀφροδισιεῦσιν· ἀλλὰ τόδε τὸ φρέαρ ἐς συγγραφὴν παρέχεται κυμάτων ἦχον ἐπὶ νότῳ πνεύσαντι. καὶ τριαίνης ἐστὶν ἐν τῇ πέτρᾳ σχῆμα· ταῦτα δὲ λέγεται Ποσειδῶνι μαρτύρια ἐς τὴν ἀμφισβήτησιν τῆς χώρας φανῆναι.
There is also a building called the Erechtheion. Before the entrance stands an altar to Zeus Hypatos; here no living thing is sacrificed—they simply place cakes upon it, and they consider it unlawful to use wine. Upon entering, there are altars: first of Poseidon, on which, by an oracle, they also sacrifice to Erechtheus; then one to the hero Boutes, and a third to Hephaistos. On the walls are paintings relating to the lineage of the Boutadai; and—for the building is double—within there is a well containing seawater. This latter fact, indeed, is no great marvel, since inland peoples possess such wells—as, for instance, the inhabitants of Aphrodisias in Caria—but this particular well elicits mention because when the south wind blows, it produces the sound of waves. Moreover, in the rock there is the mark of a trident: these things are said to have appeared as testimonies for Poseidon in his dispute over possession of the land.
