@sam: It is pretty interesting how many older works that portray a similar subject can be neglected and overshadowed.  It's interesting to see, though, to see the comparisons of the newer, updated versions.  For example, Michelangelo tested what may or may not have been more appealing to the people of his time just as Donatello did with his David a century before.  I believe it all depends on the resources and the ideas that are influenced by those of the past to recreate something of a higher, more outstanding element, just like that of Tintoretto and Da Vinci's The Last Supper.

I believe that Donatello's David would have been just as influential to Michelangelo who was already destined to become an artist.  I believe size does matter as it challenges the perspective of the audience whether it is uniquely small or enormously big.  Something outrageous will always capture the eye of the viewer.
