Northern Renaissance Art: Similarities?

There are so many similarities in themes, functions, symbolism and many other aspects of Northern Renaissance art. In previous blog posts I've gone over themes of suffering and torture, symbolism through idioms and devotion, controversy in Northern Renaissance art. This time I'm going to see if you guys can't pick out not only different themes or functions of the pieces, but if you can relate them to each other.

I've chosen five different pieces, all from the Northern Renaissance, that can be linked in some way. Can you figure out how? Some pieces are ones we have seen before, so feel free to go back and read about some of them if you need some hints.
