Dorian Gray, anyone?

While it's obviously not part of Tamrielic lore, the concept of Dorian's portrait seems to fit quite nicely with (some of the more unusual) magic in Tamriel. Though it might manifest a little differently (transferring your age and sickness to a trapped black soul, perhaps?)

Something along those lines might be created by some practical application of necromancy, a bargain with Clavicus Vile, or what used to be called Mysticism.
