Clay model Left Foot of Day with Hook

Michelangelo's Left foot of Day 1524-1531

According to Paul LeBrooy, in "Michelangelo's Models", Von Praun bought this model from Alessandro Vittorio, a former favorite student of Michelangelo. In 1562 Vittorio acquired this model from a Bologna art dealer named Nicolo Zolfino for three Venetian skudi.

The model was latter sold or gifted to Johan Schardt who was a friend of Vittorio, When Schardt died in 1562 it ended up in the Von Praun collection as his work. In 2008, the model was reported to be in a private collection in the USA.
