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. Biography Background The exact parentage of Domentziolus is unclear: Phocas had two known brothers, Comentiolus and another also named Domentziolus, who has sometimes been suggested as the younger Domentziolus's father. Shortly after the accession of Phocas, in 603, the younger Domentziolus was raised to the titles of vir gloriosissimus, patricius and curopalates.. General in the East Domentziolus, however, is better known as a general in the Byzantine-Sassanid War of 602–628. Phocas's elevation to the throne had been recognized by neither the Sassanid Persian shah Khosrau II, nor by Narses, the Byzantine governor
