The first reference to the 
windmill in Europe is made by a Dean Herbert of 
East Anglia, whose mills are supposedly in competition with the abbey of 
Bury St Edmunds.  This is probably an invention imported from interaction with the 
Muslim world, since the first 
windmills were most likely innovated from the Bana Musa brothers in the 
Islamic Middle East during the middle 9th century.  The 
windmill will spread in the other direction, to be introduced to 
China by as early as 1219.
