I'm at the Bargello today, home of Donatello's statue of David (a fey little giant-killer). There is a tour guide who speaks English with a very heavy Italian accent leading a group of middle-aged ladies along. She, her group and I are in a room with lots of small decorative sculptures, the products of workshops and schools from the Medici era.
By one case, she announces that it holds "the twelve lovers." This strikes me as odd, considering the statues inside are of men wrestling with each other, animals or monsters. She says it several times, and I finally realize she is saying "the twelve labors," as in Hercules. Got it. That changes everything.
