Subject Description
A conjurer performs a cup-and-ball trick for a crowd. The central theme is human gullibility and deception; while the main victim leans in so far he vomits a frog, a pickpocket in the crowd steals his purse. The composition uses a low wall to focus attention on the interaction and includes symbolic elements like the owl and the dog.
Condition & Value Assessment
Condition Assessment
Good (based on the primary version in Saint-Germain-en-Laye); typical age-related craquelure and stabilized wood support.
Estimated Market Value
$15,000,000 - $25,000,000 (if a fully autograph Bosch appeared on market)
Auction Estimate
$10,000,000 - $20,000,000
Provenance History
The most famous version is in the Musée Municipal in Saint-Germain-en-Laye, acquired in 1872 via the Duc de Berry collection; several other contemporary workshop copies exist.
Art Historical Significance
A seminal example of genre painting that transitions from purely religious themes to moralizing secular social commentary. It establishes Bosch's unique preoccupation with folly and sin.
Notable Features
The 'frog' motif emerging from the victim's mouth symbolizes the loss of reason or the devil's influence; the pickpocket's spectacles suggest a false sense of scholarly observation.
Condition Issues
Historic versions show various degrees of thinning glazes, minor retouching in the sky and background, and some vertical cracking along the panel joins.
Conservation Recommendations
Professional cleaning of discolored varnish, climate-controlled environment (50% RH), and UV-filtered lighting to prevent pigment degradation.
