Marvel's Mill (or Marvell's Mill) on the River Nene in Northampton, England, was the world's second factory for spinning cotton, the first to be operated as a water mill, and the first to be driven by an inanimate power-source.[2] Opened by Edward Cave in 1742, it was one of the Paul-Wyatt cotton mills that used the roller spinning machinery invented by Lewis Paul and John Wyatt, which had first been used in their Upper Priory Cotton Mill in Birmingham in the summer of 1741.[3]
