A manuscript held in the Harvard Law School library for nearly 80 years reportedly has been confirmed as an authentic 1300 original of the Magna Carta. The document, cataloged as HLS MS 172, was acquired by the university in 1946 for $27.50, under the assumption that it was merely an unofficial copy made in 1327. Academics now classify it as one of the world's most valuable historical artifacts.

The discovery was made by Professor David Carpenter of King’s College London and Professor Nicholas Vincent of the University of East Anglia. While analyzing digitized images from the Harvard collection, Carpenter suspected the document was an original confirmation issued by King Edward I. The pair subsequently used ultraviolet light and spectral imaging to verify the text and handwriting.

Authentication efforts focused on specific details, including the unusual capital 'D' in the word 'Edwardus,' which matched known originals. The professors confirmed that the text and dimensions were identical to the six previously known 1300 originals. Professor Carpenter described the find as a cornerstone of Western constitutional history, asserting the principle that rulers are subject to the law.

Provenance research suggests the document originated in the town of Appleby, Cumbria. It was reportedly passed down through the Lowther family before being given to the abolitionist Thomas Clarkson. The manuscript eventually moved through the Maynard estate before being sold at a Sotheby’s auction in 1945, where it was purchased by a London bookseller for £42 shortly before Harvard acquired it.

There are currently 24 surviving original Magna Carta documents from the various editions issued between 1215 and 1300. Most remain in the United Kingdom, though others are held in Washington, D.C., and Canberra. The 1300 version is considered particularly authoritative, representing a vital evolution in the history of human rights and constitutional governance.

Harvard Law School officials expressed pride in the discovery, noting that it highlights the importance of opening archival collections to scholars. Amanda Watson, the assistant dean for library services, stated that the revelation demonstrates how librarians create pathways for significant historical insights, even when materials remain hidden for decades.

While the professors have avoided placing a specific monetary value on the find, they noted that a 1297 Magna Carta sold at auction in 2007 for $21 million. The team hopes the document will soon be displayed to the public to ensure its message and historical significance are more widely understood.
