Pompeianus

Tiberius Claudius Pompeianus Quintianus (170-between 212 and 217) was the son of Syrian Roman Consul Tiberius Claudius Pompeianus and Annia Aurelia Galeria Lucilla. His maternal grandparents were Roman Emperor Marcus Aurelius and Roman Empress Faustina the Younger, and his uncle was Roman Emperor Commodus.

During the reign of Roman Emperor Caracalla (211-217), Pompeianus was put in charge of the Roman military campaigns and awarded two consulships, one as a Suffectus in 212. However, for some reason that does not appear in the Fasti, he appears to have been murdered during a robbery.
