Pe'gasus
a Roman jurist, one of the followers or pupils of Proculus, and praefectus urbi under Domitian (
Juv. 4.76), though Pomponiuts says that he was praefectus under Vespasian (
Dig. 1. tit. 2. s. 2.47). Nothing is known of any writings of Pegasus, though he probably did write something ; and certainly he must have given
Responsa, for he is cited by Valens, Pomponius, Gaius (3.64), Papinian, Plaulus, and frequently by Ulpian. The Senatusconsultum Pegasianum, which was passed in the time of Vespasian, when Pegasus, was cosisul suffectus with Pitsio, probably took its name from him. (Gaius, 1.31, 2.254; Inst. 2. tit. 23.6, 7.)
The
Scholia Vetera of Juvenal (4.77) has the following, coitmment : "Hinc est Pegasianum, scilicet jus, quod juris peritus fuerat ;" and in 5.79, "juris peritus fuit Lit praaefectus; und jts Pegasianum," which schopen proposes to emend : "juris peritus, fuit urbis praefeitus; tunde et S. C. Pegasianum ;" which is a probable emendation.
The expression "jus Pegasianum" has been compared with "jus Aelianum," but we know of no writings of Pegasus which were so called. (Juvenal, ed. Heinrich; Grotius,
Vitae Jurisconsult.; Zimmern.
Geschichte des Röm. Pricatrechts, p. 322; Wieling,
Jurisprudentiu Restituta, p. 337, gives the citations from Pegasus in the Digest).
