Hermitic Life on Kythera
Theodore came to Kythera from Monemvasia, and tradition connects his arrival on the island with the period following a Roman naval action in the surrounding waters. The island was at that time largely abandoned, and he took up residence in the ruined chapel of Saints Sergius and Bacchus, living there in ascetic solitude for roughly a year.
He reposed in peace on May 12, in the year generally given as 922. According to the account of his life, hunters from Monemvasia discovered his still-incorrupt body about three years after his death and buried him near the church where he had lived.
