Late Middle Ages
The first windmills in Europe appear in sources dating to the twelfth century. These early European windmills were sunk post mills. The earliest certain reference to a windmill dates from 1185, in Weedley, Yorkshire, although a number of earlier but less certainly dated twelfth century European sources referring to windmills have also been adduced. While it is sometimes argued that crusaders may have been inspired by windmills in the Middle East, this is unlikely since the European vertical windmills were of significantly different design than the horizontal windmills of Afghanistan. Lynn White Jr., a specialist in medieval European technology, asserts that the European windmill was an "independent invention;" he argues that it is unlikely that the Afghanistan-style horizontal windmill had spread as far west as the Levant during the Crusader period. In medieval England rights to waterpower sites were often confined to nobility and clergy, so wind power was an important resource to a new middle class. In addition, windmills, unlike water mills, were not rendered inoperable by the freezing of water in the winter.
By the 14th century Dutch windmills were in use to drain areas of the Rhine River delta.

Famous quotes containing the words late, middle and/or ages:
“Yet therein now doth lodge a noble peer,
Great England’s glory and the world’s wide wonder,
Whose dreadful name late through all Spain did thunder,”

“Reprehension is a kind of middle thing betwixt admonition and correction: it is sharpe admonition, but a milde correction. It is rather to be used because it may be a meanes to prevent strokes and blowes, especially in ingenuous and good natured children. [Blows are] the last remedy which a parent can use: a remedy which may doe good when nothing else can.”
—William Gouge, Puritan writer. As quoted in The Rise and Fall of Childhood by C. John Sommerville, ch. 11 (rev. 1990)
“Bowed by the weight of centuries he leans Upon his hoe and gazes on the ground, The emptiness of ages in his face, And on his back the burden of the world.”
—Edwin Markham (1852–1940)
