Sandro Botticelli Ferdinando Gonzaga, Duke of Mantua bought him a painting said to be a Botticelli out of historical interest "as from the hand of an artist by whom Your Highness has nothing, and who was the master of Leonardo da Vinci". That mistake is perhaps understandable, as although Leonardo was only some six years younger than Botticelli, his style could seem to a Baroque judge to be a generation more advanced. The "Birth of Venus" was displayed in the Uffizi from 1815, but is little mentioned in travellers' accounts of the gallery over the next two decades. The Berlin gallery bought
Sandro Botticelli Filippino Lippi, son of his master. In June of that year he was commissioned by the judges of commercial cases to paint two panels from a set of the Seven Virtues for their court; for some reason, only one, "Fortitude" (now in the Uffizi Gallery) was finished. Botticelli both matched his style and composition to the other panels by Piero del Pollaiuolo, and tried to outshine him "with fanciful enrichments so as to show up Piero's poverty of ornamental invention." There is often uncertainty in distinguishing between the contributions of Botticelli, the Lippis, and other pupils and imitators of Botticelli.
