 There is no account of Marruvium, however, previous to the Roman conquest of the Marsic territory; but under the Roman Empire it was a flourishing municipal town; it is noticed as such both by Strabo and Pliny, and in inscriptions we find it called "splendidissima civitas Marsorum Marruvium".It was also called Civitas Marsorum, and, in the Middle Ages, Civitas Marsicana.It is noticed in the Tabula Peutingeriana, which places it 13 Roman miles from Alba; but it was not situated on the Via Valeria, and must have communicated with that high-road by a branch from Cerfennia.
