Commemorated on October 13
The Seven Lakes Icon of the Mother of God was brought from Ustiug near Kazan on October 13, 1615 by the monk Euthymius, founder of the Seven Lakes Mother of God monastery. He blessed the place of the future monastery with this icon.
Feastdays of the Seven Lakes Icon were established in memory of its transfer from Ustiug, in memory of the deliverance of Kazan from a plague epidemic in 1654 and 1655 (June 26), and again from pestilence in 1771 (July 28). SOURCE:
