A cartoon by Leonardo (of the same subject) was so well received when it was displayed in Florence that it prompted the art historian Vasari to write,
'men and women, young and old, continued for two days to crowd into the room where it was being shown, as if attending a solemn festival.'
There is some debate about which cartoon Vasari was describing and arguments continue about the possibility of more than one copy by Leonardo. Regardless of this debate both the drawing above, and the painting in the Louvre, remain as fine examples of the artists skill and craftsmanship.
