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