Lucius Mussius Aemilianus
Lucius Mussius Aemilianus was a Roman usurper.
Mussius Aemilianus probably was of Italian stock. He was an officer in the Roman army under Philip the Arab and Valerian. The latter appointed him Praefectus of Roman Egypt, a position he held from 258 to 262.
He supported the rebellion of the Macriani against Gallienus. When the Macriani were defeated he probably proclaimed himself emperor.
Gallienus sent his general Aurelius Theodotus to Egypt to deal with Aemilianus. After a short struggle Aemilianus was defeated, captured, and later strangled in prison. Also his possible supporter Memor was executed.
