tenth-century Patriarch of Antioch
48th Patriarch of Antioch (Greek line)
Eustratios was briefly Patriarch of Antioch in late 969. Appointed by Emperor Nikephoros II Phokas, Eustratios never formally assumed office or traveled to his see due to the emperor's assassination. He is a largely obscure figure in ecclesiastical history, omitted from most traditional patriarchal lists, and is known primarily through the late 12th-century text De translationibus episcoporum.
