Focus on this artwork and discuss the Provenance.
In 1781 Leopold II chose it for the Tribune of the Uffizi, giving the monks copy in return, and also a crucifix, chalices, furniture, and silver. In 1792 it was exchanged for a group of works with the Vienna Museum. There are several ancient copies extant and a sketch, perhaps autograph, in the Treccani Collection in Milan.
