CASSIUS, LONGINUS, or L. CASS. LONGINUS RAVILLA, was tribune of the people in B.C. 137, when he proposed the vote by ballot, which was strenuously resisted by the patricians. In B.C. 127 he was made consul; and two years afterwards censor. Though equitable as a judge, he was so inflexible that his tribunal was called the "Rock of the Impeached." From the judicial severity of this Cassius, very severe judges have been called Cassiani.
