Palazzo Pitti, Florence. "La Derelitta" by Rebecca Matte Iniguez (or so marked). I assumed the internet would know all about this, but not so: it appears to be by Rebeca Matte Bello (who married Pedro Felipe Larrain Iñíguez, thus the name), but I can find out little more about the sculpture itself. Too bad. Her sculpting career seems to have stretched from 1899 to 1925, so this must date somewhere in there.
