Illus
![Tremissis issued by Emperor Zeno. Illus played an important role in Zeno's reign, by first supporting a usurper, Basiliscus, then helping Zeno regain the purple and defeat another usurper (Marcian), and finally creating and supporting a third usurper, Leontius.](/Images/godic/202502/08/Tremissis-Zeno-RIC_09141651.jpg")
![Solidus issued by Basiliscus. Basiliscus was the brother of Verina, the widow of Emperor Leo I. With the help of his sister and others, Illus among them, he forced Emperor Zeno flee from Constantinople, seizing the imperial throne. His rule however was short-lived, since he alienated the Church of Constantinople when he displayed Monophysite sympathies.](/Images/godic/202502/08/Solidus_Basiliscus-RIC_10031652.jpg")
![Aelia Verina was the widow of Emperor Leo I. Because of the connection of Illus to Pamprepius, who was hated by Verina, Illus came into contrast with the dowager empress. Verina also tried to have Illus killed, but the assassin did little harm to the Byzantine general, and was executed.](/Images/godic/202502/08/Tremissis-Aelia_Verina-s43441652.jpg")

Flavius Illus (Ancient Greek: Ἰλλός) (died 488) was a Byzantine general, who played an important role in the reigns of the Byzantine Emperors Zeno and Basiliscus.
Illus supported the revolt of Basiliscus against Zeno, then switched sides, supporting the return of Zeno (475-476). Illus served Zeno well, defeating the usurper Marcian, but came into conflict with the dowager Empress Verina, and supported the revolt of Leontius, but the rebellion failed and Illus was killed.
