Catius Clementinus was a member of the third century gens Catia, and it has been speculated that he may have been the son of either Publius Catius Sabinus (consul in AD 216), or a [Catius? Lepi]dus I[—], a suffect consul sometime during the early third century.[1]
Catius Clementinus’ early career is unknown, but in AD 230, he was made consul ordinarius alongside Lucius Virius Agricola, which is attested by a military diploma.[2] In the following year (AD 231), he was appointed Legatus Augusti pro praetore (or imperial governor) of Germania Superior, which is attested by an inscription.[3] Probably from 236/237 until 238/239 he was governor of Cappadocia, where he is attested by an inscription[4] on a miliarium.[5]
Catius Clementinus may have been the brother of Gaius Catius Clemens, suffect consul about AD 235 and Lucius Catius Celer, suffect consul about AD 241.
