The attached engraving is the exact reproduction of the parachute that the author also defines in the following terms, certainly inspired by those of Leonardo da Vinci:

With a square veil stretched out with four equal poles and having tied four ropes to the four quinces, a man without danger will be able to throw himself from the top of a tower or some other prominent place; because although, at the hour, there is no wind, the effort of he who falls will bring wind which will hold back the sail, lest it fall violently, but gradually descend. The man therefore must measure himself with the size of the sail.
