Luca Signorelli (1445/1450–1523), Pan with His Companions Making Music, c. 1489–1490, oil on canvas. Also known as The School of Pan, this monumental painting was a jewel of the Kaiser-Friedrich-Museum due to its size, historical significance, and complex layers of meaning. Painted by Signorelli for the ruler of Florence, Lorenzo de Medici, it was due to be moved to another location a few months before the fire, but the new facilities could not accommodate the size of the canvas, sealing the fate of this and many other large-scale works housed in the Flakturm Friedrichshain.
