The most interesting thing about icon painting is project planning and creation of a cathedral interior as a whole which includes wall painting, manufacturing and painting of iconostases.
The main task of wall painting is to create a single composition focusing on a man who says prayers and gazes the image of the Kingdom of God. The solution to such a task is unique and knows no equals in other forms of monumental art.
The essence of church wall painting is to interpret theology and the church architecture as its architecture is riddled with theology, but at the same time it is essentially abstract. That’s why the accuracy of composition and the power of the painted image are crucial, as they help to complete a much more important task of turning a human’s heart to God and the Kingdom of God.
