Impact Craters are marks made by meteorites on the surface of the planets they collide with, in other words, planetary mark making. In this series I have been thinking about the relationship between material and image in creation of marks. Black spots on Lenin’s face due to postmortem skin changes, the bruise on Ann Hodges’ hip caused by a meteorite, the microscopic diamonds on the surface of Saint George's Church in Nördlingen, the use of lead to lighten skin, and painting as the epitome of 30,000 years of mark making by humans.
