Da vinci drawing depicting ideal anotomical proportions what is it called?

The Vitruvian Man is a world-renowned drawing created by Leonardo da vinci around the year 1487.[1] It is accompanied by notes based on the work of the famed architect, Vitruvius Pollio. The drawing, which is in pen and ink on paper, depicts a male figure in two superimposed positions with his arms and legs apart and simultaneously inscribed in a circle and square. The drawing and text are sometimes called the Canon of Proportions or, less often, Proportions of Man. It is stored in the Gallerie DELL'Accademia in Venice, Italy, and, like most works on paper, is displayed only occasionally.[2][3]
