St. Venerable Theodosius, the Miracleworker of Totma (†1568), was the founder and abbot of the Totma monastery in the Archangel region of Northern Russia North. The monk led the most strict ascetic life, constantly being in prayer and labor. After his death, it was revealed that under his clothes, the ascetic wore iron chains and a hard-hair shirt that tormented his body until it bled. And on his head under the schema hood, he wore an iron cap. Over 150 after-life miracles are attributed to his intercession.
