apparatus." In the fifteenth century, Leonardo da Vinci designed an underwater
diving suit. Functional equipment not developed until much later. Inventors in the
eighteenth century designed practical devices for breathing underwater. Such as
diving suits and diving bells. Wearing these suits, divers could breathe underwater,
