Vox Pisces, or The Book-Fish, contayning three treatises which were found in the belly of a cod-fish in Cambridge market, on Midsummer Eve last. is a book published in 1627 with a very unusual origin.The original text of the work was found in the belly of a fish. On June 23, 1626, scholar and theologian Dr. Joseph Mede (or Mead) of Christ's College, Cambridge, was walking through Cambridge's market, when a fishwife found a small thin book (size sextodecimo) wrapped in sailcloth inside the stomach of a codfish caught at King's Lynn.These texts were attributed to protestant reformer John Frith, who was imprisoned in a fish-cellar in Oxford and later burned at the stake. The texts were published as a book the next year with a preface written by Thomas Goad. The texts have also been attributed to Richard Tracy of Stanbury Manor, Gloucestershire.
