How Much Is The Temptation of St. Anthony (panel, Nelson-Atkins) Worth?

Headline valuation: Based on available documentation and market context, a reasoned hypothetical market range for the Nelson‑Atkins Temptation of St. Anthony panel is $10–50 million (USD). This assumes the work is accepted widely as an autograph Bosch with the technical support reported by the Bosch Research and Conservation Project (BRCP); if the attribution were downgraded to workshop/follower the value would fall sharply [1][2].

The Nelson‑Atkins panel is a small oak devotional fragment (c. 38.6 × 25.1 cm) in the museum’s collection (acquired 1935, accession 35‑22) and was the subject of BRCP technical study and re‑attribution in 2016. The BRCP work (infrared reflectography, dendrochronology, pigment and layer analysis) materially strengthens an autograph ascription, but the picture’s fragmentary status limits both its iconographic centrality and its competitive appeal compared with intact, canonical Bosch triptychs [2].

Market logic driving the bracket: the lower bound ($10M) reflects the realistic ceiling for small, devotional autograph panels when compared to the very limited market for Bosch originals and the demonstrated market for high‑quality workshop/follower material (most of which trades in the mid‑five to low‑seven‑figure bands). The upper bound ($50M) reflects the scarcity premium for an accepted autograph Bosch: undisputed autograph works by Bosch are exceptionally rare in private hands and draw significant institutional and private interest when available. In short, scarcity can push an autograph panel into the multi‑million range, but fragment scale and devotional nature suppress headline pricing compared with major Bosch masterpieces [3].

Practical constraints and caveats: the panel is museum‑owned with donor/acquisition provenance tied to the William Rockhill Nelson Trust; deaccession or sale would be legally and reputationally sensitive, making a commercial transaction unlikely without exceptional circumstances [1]. Condition and conservation history (historical overpaint, subsequent restoration) will materially affect buyer confidence; the BRCP technical dossiers are essential to any formal valuation. Scholarly debate can persist for years; market pricing should be revisited if attribution consensus changes.

Recommended next steps to refine the band: obtain full BRCP and Nelson‑Atkins conservation reports (IRR plates, dendrochronology lab reports, pigment analyses), secure a provenance audit, and consult senior Old Masters specialists at the major houses for market appetite and reserve guidance. With those documents a formal, sale‑ready appraisal could narrow the range and, if presented without substantive debate, could push the estimate toward the upper half of the band.
