This is a real fantasy. This story was told by my friend, he works at a woodworking factory. Once he noticed in the trunk of a tree that was going to be processed by an unknown object. When he looked closely, it turned out that it was a copper Orthodox icon, which was literally growing into a tree. This icon of the 18th century, which means she was in the tree for many years. Probably the owner of the icon left it on a young tree, after many years the tree grew and hid the object in itself.
