I’m sure John Crok of Tetworth, Cambridgeshire, enjoyed his game of ‘guess what’s in the bag’, and won drinks at some public house in Southwark until a disgruntled husbandman, blabbed to the bailiffs. What no-one could manage to guess, and what became known to the bailiffs, was that John Crok was walking around the south bank of the Thames, with a head in a bag—capud cuiusdam Sarisini—a certain Saracen head, from Toledo.
In October of 1371, Crok was called before the court of King’s Bench at Westminster to explain himself (and the head).
If I have erred in my Latin rendering, please correct me, but be gentle. I have chosen the easy route in using the feminine noun that works for ‘forgotten’ instead of the strange verb that would be converted, through some mystical alchemy, into a perfect passive participle. So instead, we have this little construction that I hope means “the college of forgotten scholars.”
