Researchers read sealed 17th-century letter without opening it | Manuscripts and letters | The Guardian

Computer-generated unfolding sequence of a sealed letter. The researchers believe that virtual unfolding will have an impact “far beyond” the Brienne collection, because so many collections around the world contain unopened documents. “One important example is the hundreds of unopened items among the 160,000 undelivered letters in the Prize Papers, an archive of documents confiscated by the British from enemy ships between the 17th and 19th centuries,” they write in the article, titled Unlocking History Through Automated Virtual Unfolding of Sealed Documents Imaged by X-ray Microtomography. “If these can be read without physically opening them, much rare letterlocking data can be preserved.”
