Another artist we've studied this winter has been early Renaissance painter Fra Giovanni Angelico, an Italian monk. He painted golden halos around a person's head to show an inner goodness shining out for all to see. His halos were often made with real gold. Gold metal was pounded into a very thin sheet called 'gold leaf', then glued onto the wall or canvas with varnish.
Our related assignment was to paint with 'silver leaf' or aluminum foil. My children sketched a design on black paper. They cut pieces of aluminum foil to fit some of the areas in the drawing and glued them down. The foil was meant to look like jewels. They finished the pieces by painting with metallic paints. It was a great assignment!
