Another day of progress on this, The Voice of the Fish.
On June 23, 1626, a fishmonger in Cambridge, England gutted a cod and found a book inside, wrapped in a sailcloth. It was a discourse on the sacraments written by Protestant priest, John Firth, burned at the stake in 1533. Before he was executed he was imprisoned in an Oxford fish cellar, where he wrote the treatise, stuffed it in a fish, and threw the fish back out into the water, presumably. The volume was called Vox Pisces, The Voice of the Fish.
