I spent some time walking around Kazanskiy Cathedral on July 4, 6 and 7.
(The Virgin Mary of Tikhvin Icon is returning to the Tikhvin Monastery (from Chicago via Riga, Moscow and St. Petersburg) after 60 years. The legend runs that the icon was painted by Luke, one of Christ's apostles, in the 1st century AD in Jerusalem, when Virgin Mary was still alive. Then the image went to a specially built church in Constantinople. In 1383, the icon disappeared and re-emerged on the river Tikhvinka, near Lake Ladoga. Soon it became one of the most celebrated Russian religious relics. From 1560 into the 1920s the icon was kept in the Tikhvin Uspensky (Dormition) Monastery. During WWII, it was moved first to Pskov, then to Latvia, and on to the United States.)
