Passage 1.18.9
Ἀδριανὸς δὲ κατεσκευάσατο μὲν καὶ ἄλλα Ἀθηναίοις, ναὸν Ἥρας καὶ Διὸς Πανελληνίου καὶ θεοῖς τοῖς πᾶσιν ἱερὸν κοινόν, τὰ δὲ ἐπιφανέστατα ἑκατόν εἰσι κίονες Φρυγίου λίθου· πεποίηνται δὲ καὶ ταῖς στοαῖς κατὰ τὰ αὐτὰ οἱ τοῖχοι. καὶ οἰκήματα ἐνταῦθά ἐστιν ὀρόφῳ τε ἐπιχρύσῳ καὶ ἀλαβάστρῳ λίθῳ, πρὸς δὲ ἀγάλμασι κεκοσμημένα καὶ γραφαῖς· κατάκειται δὲ ἐς αὐτὰ βιβλία. καὶ γυμνάσιόν ἐστιν ἐπώνυμον Ἀδριανοῦ· κίονες δὲ καὶ ἐνταῦθα ἑκατὸν λιθοτομίας τῆς Λιβύων.
Hadrian constructed also other buildings for the Athenians, including a temple of Hera and Zeus Panhellenios; and a common sanctuary for all the gods. The most remarkable features of it are the hundred columns of Phrygian marble, and the walls of the porticoes built of the same material. There are rooms there whose ceilings are adorned with gilt and alabaster, decorated further with statues and paintings, and furnished with books. There is also a gymnasium named after Hadrian, which likewise has a hundred columns from quarries in Libya.
