Most studies of ancient technology have hitherto been based on the civilisations of the Mediterranean andMiddle East, especially those of Egypt, Greece and Rome. When the first European surveys of the surviving mines and metals industries in India were made in the 19th century the then primitive technology encountered was deemed to have been all that India had ever achieved. However, the project described in this volume has shown that in previous centuries the mining and metals industries had been much better organised, employing sophisticated and innovative technologies.Archaeological survey and excavation at three major mining and metal production sites in the Aravalli Hills of Rajasthan (Agucha, Dariba and Zawar), well away from the Graeco-Roman world, shed light on the long-term development of mining and smelting activity over 3000 years. Zinc was and still is the principal metal extracted together with minor amounts of lead and silver. The first production of zinc on an industrial scale anywhere in the world - by advanced processes of high temperature distillation - was discovered at Zawar. This led the authors to study the silver production at Dariba and Agucha, further evidence of major and complex industrial enterprises taking place well outside the Eurocentric Middle East.
