Passage 9.11.1
ἐν ἀριστερᾷ δὲ τῶν πυλῶν, ἃς ὀνομάζουσιν Ἠλέκτρας, οἰκίας ἐστὶν ἐρείπια ἔνθα οἰκῆσαί φασιν Ἀμφιτρύωνα διὰ τὸν Ἠλεκτρύωνος θάνατον φεύγοντα ἐκ Τίρυνθος· καὶ τῆς Ἀλκμήνης ἐστὶν ἔτι ὁ θάλαμος ἐν τοῖς ἐρειπίοις δῆλος. οἰκοδομῆσαι δὲ αὐτὸν τῷ Ἀμφιτρύωνι Τροφώνιόν φασι καὶ Ἀγαμήδην , καὶ ἐπίγραμμα ἐπʼ αὐτῷ ἐπιγραφῆναι τόδε· Ἀμφιτρύων ὅτʼ ἔμελλʼ ἀγαγέσθαι δεῦρο γυναῖκα Ἀλκμήνην, θάλαμόν γʼ εἱλίξατο τοῦτον ἑαυτῷ· Ἀγχάσιος δʼ ἐποίησε Τροφώνιος ἠδʼ Ἀγαμήδης.
On the left of the gates called Electran Gates, there are the ruins of a house where, they say, Amphitryon dwelt when he fled from Tiryns on account of the death of Electryon. The bedchamber of Alcmena is still discernible among these ruins. They say that Trophonius and Agamedes built it for Amphitryon, and the following inscription was engraved upon it: "When Amphitryon was about to bring here Alcmena as his wife, he prepared this bridal chamber for himself; Trophonius and Agamedes of the land of Anchasia built it."
