Domentziolus (nephew of Phocas)

Domentziolus (Greek: Δομεντζίολος) or Domnitziolus (Greek: Δομνιτζίολος) was a nephew of the Byzantine emperor Phocas (r. 602–610), appointed curopalates and general in the East during his uncle's reign. He was one of the senior Byzantine military leaders during the opening stages of the Byzantine–Sassanid War of 602–628. His defeats opened the way for the fall of Mesopotamia and Armenia and the invasion of Anatolia by the Persians. In 610, Phocas was overthrown by Heraclius, and Domentziolus was captured but escaped serious harm.
