TEANO (anc. Teanum Sidicinum)  , a town of Campania, Italy, in the province of Caserta, 21 M . N.W. of that town on the main line to Rome from Naples, forming conjointly with Calvi an episcopal see . Pop . (1901) 6067 (town); 13,505 (commune) . It stands at the S.E. foot of an extinct volcano, Rocca Monfina (3297 ft.), 643 ft. above sea-level . The cathedral dates from 1530, but has many columns obtained from the ruins of the ancient town . There is a feudal castle built by the dukes of Sessa in the 15th century . Below the town on the S.E. is the old church of S . Paride . The ancient Teanum Sidicinum (there is a Teanum Apulum, q.v., in Apulia) was the capital of the Oscan tribe of the Sidicini which drove the Aurunci from Rocca Monfina . They probably submitted to Rome in 334 B.C. and their troops were grouped with those of Campania in the Roman army . Thus the garrison of Regium, which in 28o attacked the citizens, consisted of one cohort of Sidicini and two of Campanians .

Like Cales, Teanum continued to have the right of coinage, and, like Suessa and Cales, remained faithful to Rome in both the Hannibalic and the Social

wars . Its position gave it some military importance, and it was apparently made a colony by Claudius, not by Augustus . Strabo speaks of it as the most important town on the Via Latina, and only coming after Capua among the towns in the interior of Campania . It lay on the Via Latina, here joined by a branch road from Suessa, of which remains still exist, and which continued E. to Allifae . Remains of a theatre and an amphitheatre still exist, and some extensive baths, containing several statues, and some Roman dwellings. both some way below the modern town, were excavated in 1go8 . A tomb with a Christian mosaic representing the visit of the three kings to Bethlehem was found in 1907 (V . Spinazzola in Notizie degli Scavi, 1907, 697; E . Gabrici, ibid., 1908, 399) .
