111 The quarries of Alvignano, the ancient Cubulteria, in the upper Volturnus valley, were exploited under Trajan, but the specific mention of the fact suggests that it was exceptional (CIL X, 4574). That the marble-like limestone of Vitulano was used at Pompei i (T.C.I. Guide, Campania, p. 181) is not likely. Likewise, the export of marble claimed for Salernum by Panebianco, V. (Rass. Stor. Salern., vi, 1945, p. 29Google Scholar) rests solely upon CIL X, 542, surely a stray from Ostia. On Sicilian marbles, Pace, B., Arte e civiltà, ii, p. 523Google Scholar.
