Lady with Weasel

Ludovico Sforza, the Duke of Milan, was a serial philanderer and patron of Leonardo da Vinci. Ludovico's favorite mistress, Cecilia Gallerani, is painted above with Ludovico's heraldic animal, the weasel. From spectral analysis, it has been determined that Leonardo had to redo the painting many times to get the weasel to look as much like Ludovico as possible. It certainly must have been a great life to be a court painter.
