a Roman knight, was the tutor, and afterwards the intimate friend, of Hadrian. On the death of Trajan, Attianus, in conjunction with Plotina, caused Hadrian to be proclaimed emperor; and the latter after his accession enrolled Attianus in the senate, made him praefectus praetorio, and conferred upon him the insignia of the consulship. He subsequently fell, however, under the displeasure of the emperor. (Spart. Hadr. 1, 4, 8, 15; D. C. 69.1.)
