Saint Markellos was from Apamea in Syria. He was the abbot of the Monastery of the Unsleeping Ones in Constantinople for approximately forty years. He was clairvoyant, a healer and great wonderworker. He spoke with angels and easily defeated demons and drove them out. This holy and glorious man entered into rest in the year 485.
The grace and power of God was made manifest through the Saint in many instances. Below we shall give an account of two instances in which he liberated the demon possessed by divine grace.
