I like what I've got but I'm hampered by my sources because, of course, some of my best items are in English. Since my argument is basically that the painting speaks to some of the most deeply held beliefs of early modern European culture as a whole, I don't mind crossing national boundaries, and there is, thankfully, Castiglione, but otherwise, the Italian archives are not well-represented in the digital world. This will be fun and challenging. I'll give myself till Tuesday to put together a case, but then I may have to abandon it for a while to return to bigger things.
