Afflianus
Afflianus or AEFLIANUS. MONS (the latter form of the name appears to be the more correet) was the name given in ancient times to a mountain near Tibur, fronting the plain of the Campagna and now called Monte S. Angelo, though marked on Gell's map as Monte Affliano. The Claudian aqueduct was carried at its foot, where the remains of it still visible are remarkable for the boldness and grandeur of their construction. An inscription which records the completion of some of these works has preserved to us the ancient name of the mountain. (Nibby, Dintorni di Roma, vol. i. p. 25; Fabretti, Inscr. p. 637.)
