CASTI Guidebook to Div. 1 – Pressure Vessels ASME Section VIII
Perhaps the earliest reference to the design of pressure vessels was made in about 1495 by Leonardo da Vinci in his Codex Madrid I. Quoting from a translation, Leonardo wrote “We shall describe how air can be forced under water to lift very heavy weights, that is, how to fill skins with air once they are secured to weights at the bottom of the water. And there will be descriptions of how to lift weights by tying them to submerged ships full of sand and how to remove the sand from the ships
