These drawings are based on traditional geometry of a stained glass window – four circles are placed inside a large one, as if four essences united by one idea. In Christianity number four is associated with four Evangelists, who represent teaching of Christ in four equal versions. Four is also connected to a cross. A cross as a symbol of Christ’s life on Earth can also be read as a symbol of life of a man. Vertical part of a cross shows Divine, and horizontal – profane side of life. The combination of both makes life not only possible but full of sense, and Christ proved it with his life.
