Pile driver, 16th-century artwork. This is an oblique pile driver, with the piles being driven at an angle into the ground, or in this case the bed of a river or lake. Two men (right) are raising a heavy weight (centre left) that is released from a height to fall on the pile. This is figure 23 from a book by the French inventor and mathematician Jacques Besson (circa 1540-1573). The Latin title of the book was 'Theatrum instrumentorum et machinarum' (Theatre of machines and instruments). It was originally published in around 1572. This engraving is from the 1582 edition, published in Lyon by the publisher Barthelemy Vincent.
