Explanation: Leonardo da Vincis Last Supper is a Renaissance masterpiece, though it is one which has struggled to survive intact over the centuries. It was commissioned by Duke Ludovico Sforza for the refectory of the monastery of Santa Maria delle Grazie in Milan, and in order to paint it Leonardo used an oil/tempera mix and applied it to a dry wall. He did this because he wanted to capture the look of an oil painting.
