From the description:

Some researchers believe that the infamous "poxleber" on the last folio of the Voynich manuscript is a "swear word", a profane term left by the author, or perhaps a frustrated later reader. In this video, we explore the linguistic context of medieval swearing and some relevant primary sources. As so often, I owe special thanks to Marco Ponzi, for his help transcribing Ebendorfer's Latin.
