[Book] Coffee with a Codex: The Voynich Manuscript (Facsimile)

[LisaFaginDavis]

If I said sheepskin when speaking with Beth or Dot, I mispoke - it's cowskin! At least the ten samples that were tested are.

As for "parchment" vs. "vellum", technically "vellum" is a kind of parchment and while it does mean "calfskin," in manuscript studies the term is generally only used for the extremely thin, almost translucent, high-end parchment used in, say Books of Hours. I would definitely not describe the Voynich parchment as "vellum" because that gives a misimpression about the quality of the parchment. It is not high-end, well-prepared parchment.
