Italian Art?

I have to write a paper for my Art History class on the art of my heritage. I'm Italian so I need to find 3 pieces of italian art that were made before 1300 to write about in my paper. Is Roman art considered Italian art? I don't understand the difference. Please help! And if you have any suggestions on some good websites to find Italian art I'd appreciate it!
