one of the consular envoys despatched by Didius Julianus and the senate in A. D. 192, for the purpose of inducing the troops of Septimius Severus to abandon their leader, who had been declared a public enemy. Not only did Candidus fail in accomplishing the object of his mission, but he very narrowly escaped being put to death by the soldiers, who recollected the harshness he had formerly displayed towards those under his command. We find him, nevertheless, at a subsequent period (193) employed as a legate by Severus, first in Asia Minor, against Pescennius Niger, and afterwards (194) against the Arabians and other barbarous tribes on the confines of Syria and Mesopotamia. On both occasions he did good service; for, by his exhortations and example, the fortune of the day was turned at the great battle of Nicaea; and, acting in conjunction with Lateranus, he reduced to submission the turbulent chiefs of Adiabene and Osroene. (D. C. 73.16, 74.6, 75.2; Spartian. Julian. 5.)
