Simonetta Vespucci was a young woman of great beauty whom Botticelli also painted. She was the mistress of Giuliano de Medici and died in 1476. She was only 23. Her lover, Piero di Cosimo, commissioned her posthumous portrait. He was only fifteen years old when he died. It is an idealized portrait, the image of perfect beauty. The symbolic, with the snake of eternal re-beginning and the dead trees on one side, when vivacious on the other, refer to the brief destiny of the model and the cycle of life.
