Cinna, L. Corn., a Roman who oppressed the republic with his cruelties. He was banished by Octavius for attempting to make the fugitive slaves free. He joined himself with Marius, and with him at the head of the slaves he defeated his enemies, and made himself consul even to a fourth time. He massacred so many citizens at Rome, that his name became odious, and one of his officers assassinated him at Ancona, as he was preparing war against Sylla.

Cinna, C. Helvius, a poet intimate with Caesar. He went to attend the obsequies of Caesar, and being mistaken by the populace for the other Cinna, he was torn to pieces.—Also a grandson of Pompey's. He conspired against Augustus, who pardoned him, and made him one of his most intimate friends. He was consul A. U. C. 758, and made Augustus his heir.
