CASAMARI, a Cistercian abbey in the province of Rome, 6 m. E.S.E. of Veroli. It marks the site of Cereatae, the birthplace of Marius, afterwards known, as inscriptions attest, as Cereatae Marianae, having been separated perhaps by the triumvirs, from the territory of Arpinum. We find it under the early empire as an independent community. The abbey is a fine example of Burgundian early-Gothic (1203–1217), paralleled in Italy by Fossanuova alone (which is almost contemporary with it), and is very well preserved.
