Dictionary of Greek and Roman Biography and Mythology/Otho, Salvius 3.

L. SALVIUS OTHO TITIANUS, was the son of No. 2, and the elder brother of the emperor Otho. He was console A.D. 52 with Faustus Cornelius Sulla (Tac. Ann. xii. 52; Frontin. Aquaed. 13). In A.D. 63 Titianus was proconsul in Asia, and had Agricola for his quaestor. It is related to the honor of the latter that he was not corrupted by the example of his superior officer, who indulged in every kind of rapacity. (Tac. Agric. 6). On the death of Galba in January A.D. 69, Titianus was a second time made consul, with his brother Otho, the emperor. When the latter set out from Rome against the generals of Vitellius, he left Titianus in charge of the city, but he soon afterwards sent for him and gave him the chief command in the war. It was partly through his eagerness to engage with the Vitellian troops, that his brother lost the empire; and on the downfall of the latter Titianus was so little dreaded, that he was pardoned by Vitellius - pietate et ignavia excusatus, says Tacitus. (Tac. Hist. i. 75, 77. ii. 23, 33, 39, 60.)
