The art of living under water

"Mêarten Triewald was one of Sweden's most prominent scientists, combining a sharp intellect with a natural mechanical ability. The period during which he lived saw the beginnings of the industrial revolution in Sweden. He came to England in 1716, and during the next ten years was involved in designing and building some of the earliest steam engines, improving the ventilation of coal mines, and giving some of the earliest public lectures on scientific subjects. [...] He introduced a new design for the diving bell, which was the principal apparatus for diving at that time, and also an array of tools for use in salvaging wrecked ships. The Art of Living Under Water and its supplement (Use of the Art of Living Under Water) provide a unique insight into the equipment, tools and methods of diving and salvage used in the first half of the eighteenth century, and might be described as the first manual on the subject. There were very few monographs on diving published in the eighteenth century, but Triewald's book is the largest and easily the best of them. Furthermore, it is the best and most detailed book on salvage by divers written to the end of the eighteenth century, and beyond. In 2004 The Historical Diving Society published this facsimile of two of his books. This English translation is the first printing of either work since 1741, and the first edition to appear in any language other than Swedish."--Provided by the publisher.
