Sallust. Catilinarian Conspiracy. p. XVII. The Loeb editor's footnote says of Caius Cethegus: "He also was one of the Cornelian family. In the civil wars, says De Brosses, he had first taken the side of Marius, and afterward that of Sylla. Both Cicero (Orat. in Catil., ii.7) and Sallust describe him as fiery and rash." However, some of this biography might be due to conflation with his contemporary Publius Cornelius Cethegus.
