The Facts

  • A Harvard University document, purchased for $27.50 in 1946 and long believed to be a cheap copy of Magna Carta, has been authenticated as one of only seven surviving original copies from King Edward I's 1300 reissue, potentially worth over $21 million.
  • David Carpenter, a professor of medieval history at King's College London, made the discovery in December 2023 while browsing Harvard Law School's digital library. Subsequently, the document was verified through ultraviolet light and spectral imaging analysis.
  • The document's authenticity was confirmed through multiple verification methods, including matching 19.2 by 18.6 inches dimensions, identical handwriting features, and text comparison with other known originals from 1300.

The Spin


Narrative A

The timing of this discovery is particularly significant as it reinforces the fundamental principles of institutional autonomy and protection against arbitrary state intervention. At a moment when Harvard faces unprecedented government pressure over campus policies, this document serves as a potent reminder that even state authorities must operate within legal boundaries.

Narrative B

The document's relatively modest preservation and cataloging over decades at Harvard demonstrates how even the most valuable historical artifacts can be overlooked in institutional collections. This oversight has potentially cost the university millions in proper valuation and conservation efforts, highlighting the need for more rigorous authentication processes in academic archives.
