Vitruvian man

The Vitruvian Man (click here for large picture) is a famous drawing with accompanying notes by Leonardo da Vinci made around the year 1490 in one of his journals. It depicts a naked male figure in two superimposed positions with his arms apart and simultaneously inscribed in a circle and square. The drawing and text are sometimes called the Canon of Proportions.

The drawing is in pen, ink, and watercolor over metalpoint, and measures 34.3 x 24.5 cm. It is currently part of the collection of the Gallerie dell'Accademia in Venice.

According to Leonardo's notes in the accompanying text, written in mirror writing, it was made as a study of the proportions of the (male) human body as described in a treatise by the Ancient Roman architect Vitruvius."
