CAIATIA (mod. Caiazzo)  , an ancient city of Campania, on the right bank of the Volturnus, 11 m . N.E. of Capua, on the road between it and Telesia . It was already in the hands of the Romans in 306 B.c., and since in the 3rd century Inc. it issued copper. coins with a Latin legend it must have had the civitas sine suffragio . In the Social War it rebelled from Rome, and its territory was added to that of Capua by Sulla . In the imperi& period, however, we find it once more a municipium . Caiatia has remains of Cyclopean walls, and under the Piazza del Mercato is a large Roman cistern,which still provides a good water supply: The episcopal see was founded in A.D . 966 . The place is frequently confused with Calatia (q.v.) .
