Sketcher, painter, engraver, sculptor and collector, Auguste Rodin is recognized worldwide for the exceptional authenticity of his anatomical sculptures, but drawing was his means of discovering "truth" in life and in art: for him "good" drawing represented truth and simplicity in nature; 'bad" drawing was self-conscious, mannered in its representation, and often displayed an ignorance of nature or inexact observation with attempts to mask it with artifice. Rodin was a prolific draughtsman, producing some 10,000 drawings.
