Serapion the Sindonite was a 4th-century Egyptian monk recognized for his intense asceticism and radical generosity. Living during the early growth of monasticism in the Egyptian wilderness, he was known as the Sindonite because he wore only a single coarse linen garment. He frequently sold himself into servitude to provide financial relief for others, including an idolater and a widow. His life was characterized by extreme poverty and a constant commitment to aiding the needy through his own labor and possessions.
