The NYT's says Kelley was upset over the breakup with his girlfriend. The art world seems pretty distraught about it.
Re: the Medicis. Has anyone seen the television films Roberto Rossellini made about the Medicis? They're from his "teaching films" period. Marxist didacticism... the films are very austere, anti-dramatic depictions of the economic strategies of the Medici clan. They take a little getting used to be but I found them to be captivating and rather sly.
