A special discipline is prescribed for icon painters in conformity to ecclesiastical requirements. The icon is a consecrated object, thus demanding the painter to pray and fast for divine inspiration. Even materials are blessed before they are used. Traditionally painters do not sign their name to icons. The disciplines ensure greater spiritual truth to come through the icon painter, who is limited and thus realizes only some of the religious depth contained within the art.
Icon painting is a special vocation.
The icon painter is expected to live a holy life so to be better able of expressing the spiritual realities of God. The painter is aware of his unworthiness, of his need for the grace of God and for the prayerful intercession by His holy ones. He keeps in mind the true Source of his works. In Western art forms, the artist's creativity and expertise are of primary value. In Eastern Byzantine Iconography, the value is in essence over appearance.
