Gerasimus was from Trikala in the Peloponnese of the prominent Notaras family. He was born in 1509 A.D. He lived a life of asceticism on Mount Athos, and then in Palestine, where he fasted for forty days. After that, he settled on the island of Cephalonia, where he founded a convent. By his prayer he brought down rain, healed the sick, and foretold the future. He rested in the Lord on August 15, 1579 A.D. Gerasimus was a miracle-worker both during his life and after his repose.
