or BE'BIUS, one of the most infamous informers of the latter end of the reign of Domitian, is first mentioned in A. D. 70, as one of the procurators in Africa, when he betrayed Piso, and is described by the great historian as "jam tune optimo cuique exitiosus." (Tac. Hist. 4.50.) He was afterwards governor of the province of Baetica, which he oppressed so unmercifully, that he was accused by the inhabitants on his return to Rome. The cause of the provincials was pleaded by Pliny the younger and Herennius Senecio, and Massa was condemned in the same year that Agricola died, A. D. 93; but he seems to have escaped punishment by the favour of Domitian; and from this time became one of the informers and great favourites of the tyrant. (Tac. Agric. 45; Plin. Ep. 7.33, comp. 3.4, 6.29 ; Juv. 1.34.)
