Passage 7.22.6
Τρίτεια δέ, Ἀχαιῶν καὶ αὕτη πόλις, ἐν μεσογαίῳ μὲν ᾤκισται, τελοῦσι δὲ ἐς Πάτρας καὶ αὐτοὶ βασιλέως δόντος· στάδιοι δὲ ἐς Τρίτειαν εἴκοσί τε καὶ ἑκατόν εἰσιν ἐκ Φαρῶν. πρὶν δὲ ἢ ἐς τὴν πόλιν ἐσελθεῖν, μνῆμά ἐστι λευκοῦ λίθου, θέας καὶ ἐς τὰ ἄλλα ἄξιον καὶ οὐχ ἥκιστα ἐπὶ ταῖς γραφαῖς αἵ εἰσιν ἐπὶ τοῦ τάφου, τέχνη Νικίου · θρόνος τε ἐλέφαντος καὶ γυνὴ νέα καὶ εἴδους εὖ ἔχουσα ἐπὶ τῷ θρόνῳ, θεράπαινα δὲ αὐτῇ προσέστηκε σκιάδιον φέρουσα·
Triteia is also a city of the Achaeans; though situated inland, its people likewise pay tribute to Patrae, by royal decree. From Pharae to Triteia is one hundred and twenty stadia. Before entering the city there is a tomb constructed of white marble, remarkable for many reasons, but especially for the paintings on it, done by Nikias himself. Depicted there is an ivory throne and upon it a young woman of exceptional beauty; beside her stands a servant-girl carrying a sunshade.
