Red Arc, egg tempera on calfskin parchment, 6 3/4 x 8 1/2 in.
Simple elements: rectangle, arc, diagonal; two colors. But within those basic forms are variations of surface, of light, of form; indentations, curves, reflections, shadows. A reason I stick with representation, with getting a sense of the physical presence of actual things, is the pleasure I have in getting those details right.
