Displaying fine technical skills, this bozzetto, or study for a figure of a woman draped all'antica is probably allegoric, standing on clouds, near a vase.
Arms and heads missing make it difficult to identify. The posture is close to Diana figures of the 17 th c. and 18 th c. The vase probably indicate a figure of Hebe.
The thin tunic is close to the body, while the veil is agitated by the wind.
Visible lacks. Heads and arms missing.
