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 without describing it, an altarpiece by Botticelli for the Convertite, an institution for ex-prostitutes, and various surviving unprovenanced works were proposed as candidates.

Its subject, unusual for an altarpiece, is the Holy Trinity, with Christ on the cross, supported from behind by God the Father. Angels surround the Trinity, which is flanked by two saints, with Tobias and the Angel on a far smaller scale right in the foreground. This was probably a votive addition, perhaps requested
