a Roman jurist, who wrote, according to the Florentine Index, six books, Ad Leges, by which is meant Ad Leg. Juliam et Papiam (Dig. 33. tit. 2. s. 23). The passage just cited shows that he was writing this work in the time of Antoninus Pius (A. D. 138-161). There is one passage in the Digest from the second book of Mauricianus De Poenis (2. tit. 13. s. 3), which work is not mentioned in the Florentine Index. He also wrote notes on Julianus (2. tit. 14. s. 7.2; 7. tit. 1. s. 25.1), but in place of Mauricianus some manuscripts have Martianus or Marcianus in the two passages just cited. Mauricianus is sometimes cited by other jurists. There are four excerpts from his writings in the Digest.
