a Roman jurist, a contemporary of Servius Sulpicius, and the teacher of C. Trebatius Testa, who was the friend of Cicero. (Dig. 1. tit. 2. s. 2.45; Cic. Fam. 7.8 and 17.) He is once quoted in the Digest and by Alfenus (33. tit. 7. s. 16), as having given an opinion on the meaning of the word "instrumentum," in a legacy of "a vineyard and the instruinentum thereof." Servius considered that the word instrumentum had here no meaning. Maximus said that the term included the stakes, poles, rakes, and spades; which Alfenus considers to be the better opinion, and so in fact it seems to be.
