Tibur
Now Tivoli; one of the most ancient towns of Latium, sixteen miles northeast of Rome, situated on the slope of a hill (hence called by Horace supinum Tibur), on the left bank of the Anio, which here forms a magnificent waterfall. It became subject to Rome with the other Latin cities on the final subjugation of Latium in B.C. 338. Under the Romans Tibur continued to be a large and flourishing town, since the salubrity and beautiful scenery of the place led many of the most distinguished Roman nobles to build here magnificent villas. Of these the most splendid was the villa of the emperor Hadrian, in the extensive remains of which many valuable specimens of ancient art have been discovered. Here also the celebrated Zenobia lived after adorning the triumph of her conqueror, Aurelian. Horace likewise had a country-house in the neighbourhood of Tibur, which he preferred to all his other residences. See Meyer, Tibur (1883).
