While I was looking for some reference materials, I came across two German (and sort of Dutch) Nativity scenes by Derick Baegert and Jan Joest van Kalkar. Both scenes were painted late 15th, early 16th century. Here are some of the other Nativities I’ve already posted in earlier posts. They all look very similar. It’s obvious copyright wasn’t an issue in the middle ages.

I wonder why these paintings inspired by other ones are often mirrored. Is it on purpose or is it a result of a copying process?
