Drawing is the act of marking a surface with the intent of creating a picture.
Drawing is different from writing because the latter produces letters and words. Drawing is very similar to painting. However, in period drawings were not considered finished works and were instead aids to more finished works such as paintings, sculpture, and architecture. Common drawing surfaces were parchment, prepared wooden panels and paper. Common drawing tools were charcoal, graphite, precious and semi-precious metals (silver, gold, copper), ink, and pastel.
