The history of drawing is as old as the history of humankind and has changed and developed through history. New styles developed out of the styles that came before them and changes in drawing styles as well as drawing materials. Artists in Europe before AD 1100 prepared animal skins like parchment or vellum as drawing surfaces. Paper was not made in Europe until the 1100's and for centuries artists made their preparatory drawings on tablets made from slate, wood, and wax.
