This volume represents an introduction to a new world-wide attempt to review the history of technology, which is one of few since the pioneering publications of the 1960s. It takes an explicit archaeological focus to the study of the history of technology and adopts a more explicit socially-embedded view of technology than has commonly been the case in mainstream histories of technology. In doing so, it attempts to introduce a more radical element to explanations of technological change, involving magic, alchemy, animism - in other words, attempting to consider technological change in terms of the 'world view' of those involved in such change rather than from an exclusively western scientific perspective.
The fifth volume of Dr Needham's immense undertaking, like the fourth, is subdivided into parts for ease of assimilation and presentation, each part bound and published separately. The volume as a whole covers the subjects of alchemy, early chemistry, and chemical technology (which includes military invention, especially gunpowder and rockets; paper and printing; textiles; mining and metallurgy; the salt industry; and ceramics).

Sometime around 1446 A.D., Cardinal Prospero Colonna commissioned engineer Battista Alberti to raise two immense Roman vessels from the bottom of the lago di Nemi, just south of Rome. By that time, local fishermen had been fouling their nets and occasionally recovering stray objects from the sunken ships for 800 years. Having no idea of the size of the objects he was attempting to recover, Alberti failed. For most of the next 500 years, various attempts were made to recover the vessels. Finally, in 1928, Mussolini ordered the draining of the lake to remove the vessels and place them on the lake shore. In 1944, the ships burned in a fire that was generally blamed on the Germans. John M. McManamon connects these attempts at underwater archaeology with the Renaissance interest in reconstructing the past in order to affect the present. Nautical and marine archaeologists, as well as students and scholars of Renaissance history and historiography, will appreciate this masterfully researched and gracefully written work.
