The Biglin Brothers Turning the Stake, 1873. Before beginning a large-scale painting such as The Biglin Brothers Turning the Stake, Eakins began a series of specialized studies. He outlined the space of the composition with perspective drawings, such as this sketch in graphite. Eakins also used figure studies when rendering a work, as well as landscape and architectural drawings and his own photographs (examples of which are elsewhere in the exhibition). The practice of using perspective drawings to work out the space of a painting dates back to the Renaissance, revealing Eakins?s academic training.
