Condition & Value Assessment
Condition Assessment
Excellent (based on museum-quality bronze standards); represents a world-class cast with preserved superficial patina
Estimated Market Value
$500,000 - $2,000,000 (depending on the specific cast and historical provenance)
Auction Estimate
$400,000 - $1,500,000
Provenance History
Original models commissioned by the Medici family; various casts held by the Kunsthistorisches Museum, Vienna, and the Bargello, Florence. This specific image likely comes from Kenneth Clark's 'The Nude' (1956).
Art Historical Significance
A masterpiece of Mannerist sculpture. Giambologna defined the aesthetic of the small bronze statuette, prioritizing formal elegance, virtuoso technique, and complex, multi-viewpoint compositions over narrative content.
Notable Features
Distinctive elongated proportions, intricate 'serpentine' pose, and the highly polished, reflective surfaces characteristic of Giambologna’s workshop in Florence.
Condition Issues
Common issues for this age include minor oxidation, wear to the patina on high points (knees, shoulders) from handling, and potential old repairs to delicate parts of the astronomical sphere.
Conservation Recommendations
Maintain stable humidity and temperature; handle only with lint-free gloves to prevent oil transfer; periodic application of high-grade microcrystalline wax if necessary for museum display.
