The Specialist | The Anonymous Altarpiece: Decoding a Renaissance Enigma, with Alex Bell

December 20, 2025

Key Takeaways Copied to clipboard!

  • The episode of The Specialist, presented by Intelligence Squared in partnership with Sotheby's, focuses on the acquisition of a highly enigmatic, high-quality early Netherlandish altarpiece (c. 1500-1505) by the National Gallery in London. 
  • Scientific analysis, including dendrochronology (dating the oak panel to potentially as early as 1483, used by 1517) and examination of the Order of Saint-Michel (which changed form in 1516), helped narrow the painting's creation date to the early 16th century. 
  • The painting was acquired by the National Gallery for a 'special price' of £16.4 million (net of tax), potentially marking the highest price ever paid for a work whose authorship remains uncertain, emphasizing that artistic quality can supersede attribution.

  • Key Takeaway: Dendrochronology established the oak panel could have been constructed by 1483 and used by 1517.
  • Summary: Dating techniques narrowed the timeframe: dendrochronology analyzed the Baltic oak panel boards, while the depiction of the Order of Saint-Michel (instigated in 1469, changed in 1516) confirmed the painting predates 1516. Infrared reflectography revealed confident drawing techniques but no unique idiosyncrasies to confirm authorship.
