 Cusanus wrote The Vision of God in the form of a prayer, responding to the request of the Benedictines of Tegernsee for a treatise on mystical theology. With it he sent them an “all-seeing” icon and proposed an exercise for its use to give them some understanding of God’s seeing their attempts to see God. The icon was probably a “Veronica” or image of the face of the suffering Jesus in which the eyes were portrayed as looking out of the picture plane. As a result, from whatever standpoint one looked at the painting, it seemed the eyes of Jesus looked directly into the viewer’s own eyes. Thus it could symbolize at once both God’s vision of us and our vision of God (the combined objective and subjective senses of visio Dei).
