Icons are painted as windows into Heaven, and therefore to show the Heavenly, rather than earthly, reality. Nevertheless, Icons are made of the people we love: of the heroes of the faith who are remembered and whose earthly lives are considered instructive and worthy of imitation. Therefore it is natural that, as well as depicting them in a stylized “spiritual” way, the Saints are also depicted as recognizable people, with distinct features. This guide is just a brief description of how the Holy Apostles are depicted in Icons, so that they can be more easily recognized when encountered in churches, monasteries, or wherever else an icon is found.
The fiery and impulsive Leader of the Twelve, Peter is easily recognizable by his white, short, curly hair and beard. He is often shown holding a scroll, which may have words taken from one of his Epistles written upon it. In some icons he may also be shown with keys hanging from his belt, a reference to the words Jesus said to him: “And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven.” He is often found in Icons with St. Paul, who were both martyred in Rome, holding together the Church, and showing their shared pre-eminence among the Apostles.
