Some people think that the soldiers who took part in the Crusaders in Palestine came home and brought back information about the windmill.
They do not look like the windmill now seen, but with a vertical axis, the axis of the vertical arrangement of the wing, and the carousel device is very similar to the arrangement of the Trojan horse.
The region of the world has strong winds, almost always blowing in the same direction, so for the prevailing wind and built these early windmills.
AD 7th century in West Asia - probably in Syria, built the first batch of windmills.
However, the design of Western windmills is very different from that of Syria's windmills, so they may be invented independently.
