Jacques-Louis David, is there a "definitive" version of Napoleon Crossing the Alps?
Apologies for the somewhat bumbling nature of this post. Many years ago I went to the Louvre to see, among other things, La Joconde. As I was standing in the queue, I glanced at the opposite wall and was confronted with David's Leonidas at Thermopylae. It became, and remains to this day, my favourite painting of the neoclassical era and, quite possibly, my favourite painting above all.
However, when diving into David's works I came across what is arguably his most famous painting, of Napoleon crossing the Alps. I've found multiple examples, with different cinch colours, from pale blue, to red, to black, and with very different details around the horse's eye.
My question is, is any one of these versions considered to be definitive and, if so, which one is it?
