Steel production: Forge, A with bellows to produce draught. Foreground bars are being hammered with mechanical hammer. Power source (probably water) out of picture on left, but tappets on revolving barrel would raise hammer for next blow as they engaged with a trip mechanism. After hammering bars are being slaked in water. Agricola 'De re metallica' Basle 1556. Woodcut
