Leonardo DaVinci is the most well known artists from the Italian Renaissance, creating multiple masterpieces that have lasted the centuries. However, there were many of his pieces that he did not complete. It was actual known that Leonardo was quite unreliable to finish commissioned pieces. His Adoration of the Magi was one of those incomplete pieces; originally being commissioned for the monastery of San Donato a Scopeto, near Florence as an altar piece. He was paid in land and with some unusual stipulations. The ambitious piece, with sixty-six human beings and eleven animals, never made it past its groundwork in yellow ocher.
There is a great degree of symbolism that Leonardo worked into the painting, all of which can be read about on this website:http://www.lairweb.org.nz/leonardo/magi.html
