Donatus of Evorea was a 4th-century priest and bishop from Epirus Vetus, a region in northwestern Greece. Living during the era of Emperor Theodosius I, he is remembered for his various legendary feats, including the slaying of a dragon and the restoration of life to the deceased. His life and ministry were centered in Euroea, which is identified with modern-day Glyki. He is honored as a saint in both the Roman Catholic and Eastern Orthodox traditions, particularly within Greece and Albania.
