He was known for his multi-volume work entitled De - Architectura.
His discussion of perfect proportion in architecture and the human body led to the famous Renaissance drawing by Leonardo da Vinci of Vitruvian Man.
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 del' Academia 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.
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 Arcitectura.
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.
