a Roman jurist, who is cited by Valens (Dig. 36. tit. 1. s. 67), by Pomponius, who couples him with Aristo (Dig. 40. tit. 5. s. 20), and by Paulus, who joins him with Proculus (Dig. 18. tit. 6. s. 8), from which we may conclude that he lived after the time of Tiberius. It has been conjectured that he wrote oh the Lex Julia et Papia, but the passages alleged in proof of this (Dig. 23. tit. 2. s. 44, 40. tit. 9. s. 32) are not decisive. He is also quoted by Ulpian and others.
