On the topic of the nude statues, I have no evidence for this idea, except: modern toy dolls are often "nude," with the idea children will put clothes on them. Is it possible that the Greeks put different clothes and decorations on their nude base statues, clothes which are now gone, evanescent as the paint that once adorned the marble statues as well?
i wonder if some future civilization will find the clothing store mannequins we throw away today and wonder if that was the best we could do
now I'm wondering if David was actually made to stand outside a tunic store, but Michelangelo just got carried away with the simple commission, and the rest of the story about the cathedral was made up
