June 23. In 1626 Mr Mead of Christ's College, Cambridge, passing through the city's market, noticed a battered book which had just been found by a fishwife inside the belly of a plump codfish from King's Lynn. Mr Mead bought the book, a religious tome written by John Firth, who had spent some time imprisoned inside a fish-cellar in Oxford for his religious beliefs! The book was reprinted by the Cambridge Authorities under the title 'Vox piscis' and illustrated with a woodcut showing the book, the fish stall and the knife which had cut open the fish.
