Titus Quinctius Crispinus Valerianus was a Roman senator, who was active during the reign of Augustus. He was suffect consul in the second half of AD 2 as the colleague of Publius Cornelius Lentulus Scipio.[1]
Crispinus Valerianus was of Patrician descent, but his familial connections beyond that are unclear. He could be the biological son of a Valerius who was adopted by Titus Quinctius Crispinus Sulpicianus, one of the alleged lovers of Julia the Elder; or the son of a Quinctius Crispinus and a Valeria;[2] or even the brother of Crispinus Sulpicianus.[3]
One certain event in his life is the date of his praetorship, which was in 2 BC;[3] this allows us to infer he acceded to the consulate anno suo, and fixing the year of his birth as 32 BC. We know that he was a member of the Arval Brethren, for inscriptions confirm his presence at their ceremonies from AD 14 through 27.[4] He likely died before the end of the reign of Tiberius.
