I don't get your point on Michelangelo. We can very easily describe the process if we could see it. We just can't cause he's dead and he was not big on YouTube,

I don't get your point on Michelangelo. We can very easily describe the process if we could see it. We just can't cause he's dead and he was not big on YouTube, even then we can explain a lot from evidence. Its much more complex to explain why we classify them as masterpieces than how he made it.
