This antique (circa mid-17th century) Russian Orthodox Icon of Christ the Teacher with Guardian Angel and Saint on each side was hand painted on a slab of wood by the egg-yolk tempera, well-known technique used in Russian Orthodox iconography from ancient times. This icon has a depression that was hollowed out for the main representation, the so called “kovcheg" (ark or shrine), which is separated from the elevated margin or border by the “luzga", a shallow angled edge. This icon has two parallel pins giving an opportunity for wood slab to "walk". In the beginning of xV century the icons began to have pins (pegs) embedded into the back of the board into specially carved grooves to prevent any warping of the wood panel. The icon measures 12 inches in length, 10 ½ inches in width, and is 1 inch thick.
