Lucius Salvius Otho Titianus was the elder brother of the Roman Emperor Otho (reigned 69 AD). As a Roman senator, he was consul in the year 52 as the colleague of Faustus Cornelius Sulla Felix,[1] and appointed consul as his brother's colleague for the period from Galba's murder to the end of February.[2] Titianus was given the daily responsibilities of the emperor by Otho when Otho left Rome to halt the advance of Vitellius into Italy.[3] Subsequently, Titianus was appointed generalissimo in charge of the war by Otho[4] and was present at the First Battle of Bedriacum.
Titianus was a member of the Arval Brethren, serving as promagistrate at least five times beginning in the year 57 into the year 69.[5] The sortition awarded him the proconsular governorship of Asia for the term 63/64.[6]
Titianus was married to Cocceia, sister of the future Emperor Nerva (reigned 96–98), with whom he had a son, Lucius Salvius Otho Cocceianus. Cocceianus rose to become consul around 80, but was later executed under orders of Emperor Domitian, for having observed his uncle Otho's birthday.[7]
