I did take a quick look and there are a few possibilities. Under applications there is an art history one which includes terms and categories. There is also a drawing term application. Both are from the same company and have duplication.
There is also some iTuneU broadcasts under art. I don't know how much terminology they offer but might be good reference for understanding as you familiarize yourself with the terminology.
But if you do find yourself fully interested in it, the best thing is to locate some books and/or DVDs on the subject or visit some museums.
