Leonardo di ser Piero da Vinci
April 15, 1452-May 2, 1519 (aged 67)
Leonardo's most famous painting of the 1490s is The Last Supper, painted for the refectory of the Convent of Santa Maria della Grazie in Milan. The painting represents the last meal shared by Jesus with his disciples before his capture and death. Among the works created by Leonardo in the 16th century is the small portrait known as the Mona Lisa or "la Gioconda", the laughing one. In the present era it is arguably the most famous painting in the world. The Vitruvian Man 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.
