Lucius Roscius Aelianus Maecius Celer

Celer's cursus honorum is partially known from an inscription set up at Tibur by his friend, Gaius Vecilius Probus;^[4] Anthony Birley notes that "Vecilius Probus gave only a selection of posts on the Tibur inscription. Otherwise, it would certainly be curious that he held a relatively early consulship, with no appointments in the imperial service to his credit."^[5] According to Probus, Celer's career began as one of the decemviri stlitibus iudicandis, one of the four boards of the vigintiviri, a preliminary and required first step toward gaining entry into the Roman Senate. Celer was then military tribune in Legio IX Hispana, which was stationed in Roman Britain. During Domitian's Chattan War of 83, two vexillations were sent from Legio IX to Germany, one under Celer, the other under Velius Rufus. For Celer's efforts in the conflict, he was awarded Dona militaria appropriate for his rank.^[6] He was admitted to the Senate when he became quaestor for an unnamed emperor, possibly Domitian; this was followed by the traditional republican magistracies of plebeian tribune and praetor. Syme argues the date of his praetorship fell in the years 90 to 94, making him a contemporary of Tacitus.^[7] Celer's consulate followed.

The only office Celer is known to have held after his consulate is the proconsular governorship of Africa, which Werner Eck has dated to 117/118.^[8] His life after this governorship, as well as the date of his death, is unknown.
