Cassius Apronianus was a Roman senator who lived in the 2nd century. It has been conjectured that he supposedly married the daughter of the Greek historian, orator, and philosopher Dio Chrysostom.[1][2] Their son was the historian, consul and senator Cassius Dio.[3]
Apronianus was originally from Bithynia (modern northwestern Turkey). He was governor of Lycia et Pamphylia around 179/180,[4] then of Cilicia (modern southeastern Turkey) c. 180 - c. 183,[5] where he was joined by his son Dio.[1] Apronianus became suffect consul most likely around 185,[4] after which he served as governor of Dalmatia (modern Dalmatia, Croatia).[3]
