The etching is based on Giulio Romano's design for the central ceiling panel of the Camera degli Imperatori at the Palazzo Te in Mantua. Both a preparatory drawing by Giulio Romano (Chatsworth, inv. no. 116) and the modello (Louvre, Paris, inv. no. 3546) for the fresco are preserved.
We are grateful to Catherine Jenkins, London, for her help in cataloguing this lot.
