<Tr> <Th> Location </Th> <Td> Gallerie dell'Accademia, Venice </Td> </Tr> <P> The Vitruvian Man (Italian: Le proporzioni del corpo umano secondo Vitruvio, which is translated to "The proportions of the human body according to Vitruvius"), or simply L'Uomo Vitruviano (Italian pronunciation: (ˈlwɔːmo vitruˈvjaːno)), is a drawing by the Italian polymath Leonardo da Vinci around 1490 . It is accompanied by notes based on the work of the architect Vitruvius . The drawing, which is in pen and ink on paper, depicts a man in two superimposed positions with his arms and legs apart and 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 kept in the Gabinetto dei disegni e stampe of the Gallerie dell'Accademia, in Venice, Italy, under reference 228 . Like most works on paper, it is displayed to the public only occasionally, so it isn't part of the normal exhibition of the museum . </P> <P> The drawing is based on the correlations of ideal human proportions with geometry described by the ancient Roman architect Vitruvius in Book III of his treatise De architectura . Vitruvius described the human figure as being the principal source of proportion among the classical orders of architecture . Vitruvius determined that the ideal body should be eight heads high . Leonardo's drawing is traditionally named in honor of the architect . </P> <P> This image demonstrates the blend of mathematics and art during the Renaissance and demonstrates Leonardo's deep understanding of proportion . In addition, this picture represents a cornerstone of Leonardo's attempts to relate man to nature . Encyclopædia Britannica online states, "Leonardo envisaged the great picture chart of the human body he had produced through his anatomical drawings and Vitruvian Man as a cosmografia del minor mondo (cosmography of the microcosm). He believed the workings of the human body to be an analogy for the workings of the universe ." </P>
