Marcus Caeionius Silvanus

Marcus Caeionius Silvanus was a Roman senator of the second century AD. He was the ordinary consul of 156 with Gaius Serius Augurinus as his colleague.[1] However, nothing more is presently known about his career.

Based on his cognomen Silvanus, Ronald Syme suggested that he was descended from the Plautii, specifically that his father was a son of Lucius Ceionius Commodus, consul 106, and Ignota Plautia, who died before he was old enough to be awarded the consulate. "Hence an unattested and short lived brother of L. Caesar -- and his son, M. Ceionius Silvanus, was therefore a first cousin of L. Verus."[2]

Christian Settipani has proposed that Silvanus was an ancestor of Ceionius Varus, urban prefect of Rome from 284 to 295.[3]
