A Most Certain, Strange, and true Discovery of a Witch.
This 1643 woodcut shows a witch surfing on a plank across the River Kennet at Newbury. Shot at by Parliamentarian soldiers, she reportedly caught and ate the musket balls, until finally being brought down.
Witches, having rejected baptism (as the demonologists saw it) could not sink in water, which rejected them. Hence their ability to sail in sieves (Scotland), and the notorious swimming test promoted by the 1613 pamphlet, Witches Apprehended, Examined and Executed.
