Gates of Paradise

I've had a recurring dream for the last few nights.  In the dream I am being quizzed (by persons unknown) about the artistic significance of Lorenzo Ghiberti's door panels for the Baptistry in Florence - known as the Gates of Paradise.  And question after question, the only things I can remember about art history pertains to Caravaggio's use of light in The Death of the Virgin.

I have this dream not only every night, but multiple times a night.  I don't get it.  And it's making me crazy.

 This is one of the panels from the Gates of Paradise.

This is Caravaggio's Death of the Virgin.

If you get a chance, take a look at all of the panels of the Gates.  They're breathtaking.
