The first step in creating an icon is to analyze the prototype/model. Each icon has an underlying geometry which gives the composition unity, balance, and harmony. Since icons are often intended to be used liturgically inside an Orthodox church, using geometry not only gives harmony to individual icons, but also continuity to groups of icons at the altar of the church. It helps them have similiar composition and proportions without being so rigid that they are all exactly alike. There is room for creativity here, while maintaining the sense of unity.
I have begun to analyze the form and composition of St.George today, finding the important triangles, size relationships, and curves. It is important to maintain a sense of stillness, timelessness, and compositional balance without being overly static. The triangles and modules will also serve as a guide for enlarging the photo of our model to our working 3X4 foot design from a 7X10 inch photo.
