Not really a new member, but lapsed.  I'm an art historian lecturing at Birkbeck College, London, and currently on study leave.  I'm working primarily on the Arena Chapel, in Padua, a church which as well as having frescoes by Giotto (which I feel I know something about), also poses numerous questions about medieval religion, about which I know little.  So, while I doubt that I have much to offer, I have much to learn from the list.
