Theophanes the Confessor
Ascum () was a general of the Byzantine Empire, active early in the reign of Justinian I (r. 527–565). He was in command of the Praetorian prefecture of Illyricum. His name is reported by John Malalas. Both Theophanes the Confessor and George Kedrenos render his name "Ακούμ" (Acum).
