Giotto di Bondone (1266/7 – January 8, 1337), better known simply as Giotto, was an Italian painter and architect from Florence in the late Middle Ages. He is generally considered the first in a line of great artists who contributed to the Italian Renaissance. This is a painting called "The Annunciation". It's not such a great reproduction as far as colours go, but you can see the quite impressive colour scheme of the angel's wings! The picture is actually a painting on a wall. It is known as a fresco.  There is a lovely Christmas carol about this particular scene, called The Angel Gabriel. here is the youtube link for that :http://www.youtube.com/watch?v=pliqObTHxUQ&feature=related
