Life and Captivity
The synaxarion relates that Agapius served as a novice in strict obedience to an elder who lived in silence at the Holy Trinity kellia at Kolitsa, a dependency within the boundaries of the Vatopedi monastery on Mount Athos. When Turkish invaders landed on the Athonite shore, they captured him and transported him to Magnesia, where he was held in chains and made to labor for twelve years. Throughout his captivity he is said to have remained steadfast in faith, praying earnestly to the Mother of God.
By tradition, the Mother of God appeared to Agapius in his sleep and instructed him to return to his elder without fear. When he awoke he found that his bonds had fallen away and the doors stood open, and he escaped and made his way back to Mount Athos.
