In high school it was literature and I enjoyed it in college as well. It's interesting to read something someone wrote 300, 500 years ago and still be able to identify with the characters and the theme.
My single favorite class was Art History from the cave man to the Renaissance. I took the class because it filled a slot but I really enjoyed learning about the way cavemen used the contours of the cave walls to paint their images and the Egyptians were required by law to paint people with specific proportions, the use of light, shadows and depth. It was a fun class.
Even though I majored in Business and Management, those were my favorite classes.
