De Arte Natandi (‘The Art of Swimming’), by Sir Everard Digby, published in England in 1587 but written in Latin, was the first treatise on the topic published in Britain. Written in an age when many people could not swim and drowning was a regular cause of death, it features advice on different swimming techniques.
