Simple question! will mark brainliest! why are there very few paintings with unclothed people in northern renaissance paintings? i know its a weird question but its for my homework

so, not gonna do the actual thing because that's just laziness for an easy assignment like this.

but someone that has a lot of information and interesting details about is picasso. you can easily write a 500 word essay about him and how overtime his paintings of himself got more and more deformed representing that he was forgetting what he looked like and that was from memory.
