My order is probably history, literature, science, art.
I took a short humanities class in college that covered just a few artists, architecture, drama, etc. I'd enjoyed and looked up art a fair amount on my own, but it does help if you have someone teaching you things that you can't just tell by looking at a painting. Like, Monet - he does what's called pointillism, which is sort of amazing. He put thousands of little dots of paint on canvas to compose his famous water lilies and such:
That's insane dedication to me, and I find it fascinating - but would never have been able to tell by looking at the painting.
My first grader and I spent about 40 minutes just looking up famous paintings the other night on my iPad, at her request - it was amazing, I was so shocked that she was interested at 6.5. I think your brain is just wired to remember certain types of things, and I think hers is similar to mine - it makes total sense that a more mathematical-leaning mind would remember science and history (with all of its dates) rather than art.
