Passage 3.19.1
τοῦ θρόνου δὲ ᾗ καθίζοιτο ἂν ὁ θεός, οὐ διὰ παντὸς κατὰ τοῦτο συνεχοῦς ὄντος ἀλλὰ καθέδρας παρεχομένου πλείονας, παρὰ δὲ καθέδραν ἑκάστην ὑπολειπομένης καὶ εὐρυχωρίας, τὸ μέσον ἐστὶν εὐρυχωρὲς μάλιστα καὶ τὸ ἄγαλμα ἐνταῦθα ἐνέστηκε.
As for the throne at the point where the god would sit, it is not continuous throughout at this place, but instead provides several seats, and by each seat there remains an open space; the central space is the widest of all, and it is there that the statue has been placed.
