Saint Sabbatius of Tver pursued asceticism with the blessing of Saint Arsenius, Bishop of Tver, at a distance 15 versts from Tver. Saint Sabbatius established a monastery there, known for the strictness and holiness of its rule. Such ascetics as Saint Joseph of Volokolamsk (September 9) and Saint Cornelius of Komel (May 19) went there to be instructed in monasticism. The chains found in the cave where Saint Sabbatius practiced silence testify to his ascetic deeds. He died no later than the year 1434.
