I've seen a lot of paintings / depictions of Cristopher Columbus interacting with the native inhabitants of the "New World", and in most of the them the natives are nude, or mostly nude, especially the women. The men usually have a loin cloth or something, but were these depictions accurate? Or are they simply a result of artistic embellishment?

Also this may be a silly question but were breasts sexualized, by the native populations (or even by the European settlers) in a way that is comparable to how they are sexualized nowadays?
