4. C.Cornelius, a Roman knight, and one of Catiline's crew, undertook, in conjunction with L. Vargunteius to murder Cicero in B. C. 63, but their plan was frustrated by information conveyed to Cicero through Curius and Fulvia. When accused subsequently, he could obtain no one to defend him; but he escaped punishment probably on account of the information he gave respecting the conspiracy. When P. Sulla was accused in B. C. 62 of participation in the conspiracy, Cornelius caused his son to come frward as a witness against him. (Sal. Cat. 17, 28; Cic. pro Sull. 2, 6, 18.)
