Before the use of cannon and other gun-powder artillery, siege engines relied on assorted sources of power, from torsion ''energy storage'' systems to man-power, counter-balances and others. This book reveals how technological traditions from the Graeco-Roman world, Persia, India and above all China made a massive contribution to siege warfare techniques. It also covers developments in military engineering, such as mining, counter-mining, the breaking of walls, the use of noxious and chemical fumes and the use of fire-weapons.","brand":"Bloomsbury Publishing PLC","offers":[{"title":"Default Title","offer_id":51864054890839,"sku":"9781841762357","price":12.34,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0817\/1739\/5799\/files\/9781841762357.jpg?v=1759921512","url":"https:\/\/bookcurl.com\/products\/medieval-siege-weapons-9781841762357","provider":"Book Curl","version":"1.0","type":"link"}
