From the CBC:
The University of Calgary has acquired a 521-year-old treasure from medieval England — one of the earliest books ever published in English.
Called the Polychronicon, the book chronicles the history of the universe, as was understood in the 14th century, and is available for viewing by the public.
There are only about 50 copies left in the world, and few are in such pristine condition (though the cover, boards and bindings had to be replaced).
From the University of Calgary:
“We are fortunate to not only acquire a significant early printed work of medieval history, but also to acquire one that is written in English, the first English incunable we’ve acquired,” explains Annie Murray, associate university librarian for Archives and Special Collections. “This English translation of the Polychronicon is both an accessible text and a fascinating historical object.”
