A.E. Popham, The Drawings of Leonardo da Vinci (London: Random House, 1946), 297.
Drawings of suction pumps. This is one of da Vinci’s many invention blueprints of machines. In particular I included this drawing to compare to his anatomical drawings. A lot of the lines and measurements used in this drawing are very similar to the ones used in the drawings of the body. It is very evident that he approached the body the same way he did machines.
