Why it surfaced
The opening feature tackles the Voynich Manuscript with unusually confident, specific copy: a 240-page fifteenth-century book in a Yale vault that nobody can read. Its “no clickbait, no infinite scroll” promise, daily numbering, and growing archive give the project a clear editorial shape rather than a generic newsletter landing page.
