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
