In the early 1780s Pacetti had in hand a monumental marble head 41 cm high of a bearded god, which he used as a model to complete headless statues of Jupiter and Aesculapius. This head was also copied in marble, plaster and terracotta. Such a prolific use suggests that Pacetti was the sole owner of the antique marble.
The trend is to recognize Zeus in this bust with pure face lines, very long hair and curly beard that will be much later a symbol of antiquity in the surrealist compositions of De Chirico.
The marble recovered by Pacetti is the only known example of this type. A similarity of facial structure with a portrait of Alexander the Great leads to conclude that it is a copy of a Hellenistic statue. Made in Rome around the second century of the empire, the head has been carefully restored, certainly by Pacetti himself. The shoulders and the base are additions, probably by his workshop.
This antique bust on its socle from the late eighteenth century is estimated $ 800K, for sale by Sotheby's in New York on June 3, lot 34.
