A rival emperor to Diocletian. He is known only from papyri but appears to have a led a revolt from August to December 297 centered in Alexandria. Literary sources record a revolt by a certain Aurelius Achilles in Alexandria at this time, who may have been Domitianus’s supporter and successor. The revolt was crushed by early 298, and both men must have perished as a result.
