At breakfast one morning I picked up a brochure that told of a Russian Orthodox monastery just outside of Blanco, Texas. This icon is kept in a small chapel on the grounds of the monastery. We went to see it. These are Eastern Orthodox monks and nuns - never eating meat, fasting often, and praying over seven hours a day. They have hundreds and hundreds of icons available.
Icons are a huge part of the Eastern Orthodox practice.
The walls of their chapels and churches are just covered with them. I bought a copy of the Vladimir Icon. Tradition says it was painted by St. Luke. And that he wrote it on a board taken from the table used in the house where Mary, Joseph and Jesus lived and ate. In 450 the icon was taken from Jerusalem to Constantinople and then early in the 12th century to the city of Kiev in the Ukraine.
