a distinguished general under Trajan and Hadrian. He was sent by the former emperor in A. D. 115 to Egypt to suppress the insurrection of the Jews at Cyrene, which he effected without much difficulty. On the accession of Hadrian (A. D. 117), with whom he had lived on intimate terms during the life-time of Trajan, he was raised to offices of higher honour and trust. He was first sent into Mauritania to quiet the disturbanee in that province which were supposed to have been excited by Q. Lusius Quietus [QUIETUS], and he was afterwards appointed to the government of Pannonia and Dacia with the title of Egyptian Praefect, that he might possess greater weight and influence. Subsequently he was summoned to Rome, and raised to the important dignity of Praefectus Praetorio in place of Attianus. In the discharge of the duties of this office, he was most assiduous; but nevertheless, like all the other friends of Hadrian, was at length treated with ingratitude by the emperor. Turbo was fifty years of age at the time of his death, as we learn from an inscription on his tomb. (Euseb. Hist. Eccl. 4.2 ; Spart. Hadr. 4-9, 15; D. C. 69.18 ; Gruter, p. 437. 1.)
