A surviving medieval windlass, dated to 1360 –1400, is in the Church of St Mary and All Saints, Chesterfield. [2] The oldest depiction of a windlass for raising water can be found in the Book of Agriculture published in 1313 by the Chinese official Wang Zhen of the Yuan Dynasty (fl. 1290–1333). [3]
Rather, old and new machinery continued to coexist on medieval construction sites [8] and harbours. [6] Apart from treadwheels, medieval depictions also show cranes to be powered manually by windlasses with radiating spokes, cranks and by the 15th century also by windlasses shaped like a ship's wheel.
The place in which the bells are now housed once held a builders' windlass, which survives as one of the few examples of a medieval crane in existence, and the only one from a parish church. It is on display at Chesterfield Museum and Art Gallery. [26]
The Siege and Destruction of Jerusalem by the Romans Under the Command of Titus, A.D. 70, by David Roberts (1850), shows the city burning. Early thermal weapons, which used heat or burning action to destroy or damage enemy personnel, fortifications or territories, were employed in warfare during the classical and medieval periods (approximately the 8th century BC until the mid-16th century AD).
The term "arbalest" is sometimes used interchangeably with "crossbow". Arbalest is a Medieval French word originating from the Roman name arcuballista (from arcus 'bow' + ballista 'missile-throwing engine'), [3] which was then used for crossbows, although originally used for types of artillery.
The arbalest was a heavy crossbow that required special systems for pulling the sinew via windlasses. For siege warfare, the size of crossbows was further increased to hurl large projectiles, such as rocks, at fortifications. The required crossbows needed a massive base frame and powerful windlass devices. [10]
When used as the wheel of a wheeled vehicle the smaller cylinder is the axle of the wheel, but when used in a windlass, winch, and other similar applications (see medieval mining lift to right) the smaller cylinder may be separate from the axle mounted in the bearings. It cannot be used separately.
