Da Vinci Drawings pictures also house a number of anatomical sketches by Da Vinci. It is clear that Da Vinci was a man of curiosity and science as he often sketched images of the human body. “Anatomical drawing of hearts and blood vessels” depicts a rough sketch of he human heart, as it would appear within the body.
“Sketch of a roaring lion” depicts a lion as it crouches and lifts its head as it roars towards the heavens. “Facsimile of Codex Atlanticus Screws and Water Wheels,” shows Leonardo’s sketched design for an invention, as it is very detailed and is coupled with the artists printed directions for assembly of the invention as well as each parts function.
