From the imagery on their coins, it appears that the Cassii had a special devotion to the Aventine Triad of Ceres, Liber, and Libera, for whom Spurius Cassius Viscellinus built a temple on the Aventine Hill in 494. Libertas, a goddess associated with Liber and Libera, also features regularly on their coins. She was later the emblem of the "Liberatores" during the Civil War led by Gaius Cassius Longinus and Brutus against Octavian and Mark Antony.
