AMITERNDM, an ancient town of the Sabines, about 5m. N. of Aquila, in the broad Aternus valley from which, says Varro, it took its name. Stormed by the Romans in 293 B.c. it suffered in the wars of the Republic, but its fertility made it prosperous under the empire. It lay at the point of junction of four roads— the Via Caecilia, the Via Claudia Nova and two branches of the Via Salaria. There are considerable remains of an aqueduct, an amphitheatre and a theatre, all of the imperial period, while in the hill on which the village of S. Vittorino is built are some Christian catacombs. Sallust was born at Amiternum.
