The life of St Arseny of Tver
He founded a monastery of his own on the river Tmaka near Tver, naming its first church for the Kiev fathers Anthony and Theodosius before later raising a stone cathedral of the Dormition there as well. Wanting his own monks to have the example of those earlier fathers always before them, he had a fresh copy of the Kiev Caves Patericon made from its oldest surviving manuscripts, a text still known as the Tver, or Arsenian, redaction, traditionally dated to 1406 and counted among the important witnesses to that early Russian literature.
Arsenius reposed on March 2, 1409, and was buried at the monastery he had built. His relics were found incorrupt in 1483, and a Church council formally numbered him among the saints in 1547.
