The 3rd-century mill is considered the earliest known machine to incorporate a crank and connecting rod.^[1] The Hierapolis sawmill was a Roman water-powered stone sawmill at Hierapolis, Asia Minor (modern-day Turkey). Dating to the second half of the 3rd century AD,^[2] the sawmill is considered the earliest known machine to combine a crank with a connecting rod to form a crank slider mechanism.^[1] The watermill is evidenced by a raised relief on the sarcophagus of a certain Marcus Aurelius Ammianos, a local miller. On the pediment a waterwheel fed by a mill race is shown powering via a gear train two frame saws cutting rectangular blocks by the way of connecting rods and, through mechanical necessity, cranks (see diagram). The accompanying inscription is in Greek and attributes the mechanism to Ammianos' "skills with wheels".^[3] Other sawmills[edit] Further Roman crank and connecting rod mechanisms, without gear train, are archaeologically attested for the 6th century AD water-powered stone sawmills at Gerasa, Jordan,^[4] and Ephesus, Turkey.^[5] A fourth sawmill possibly existed at Augusta Raurica, Switzerland, where a metal crankshaft from the 2nd century AD has been excavated.^[6] Literary references to water-powered marble saws in Trier, Germany, can be found in Ausonius' late 4th century AD poem Mosella. About the same time, they also seem to be indicated by the Christian saint Gregory of Nyssa from Anatolia, demonstrating a diversified use of water-power in many parts of the Roman Empire.^[7] The three finds push back the date of the invention of the crank and connecting rod mechanism by a full millennium;^[8] for the first time, all essential components of the much later steam engine were assembled by one technological culture: With the crank and connecting rod system, all elements for constructing a steam engine (invented in 1712) -- Hero's aeolipile (generating steam power), the cylinder and piston (in metal force pumps), non-return valves (in water pumps), gearing (in water mills and clocks) -- were known in Roman times.^[9] See also[edit] * List of Roman watermills * Barbegal aqueduct and mill References[edit] 1. ^ ^a ^b Ritti, Grewe & Kessener 2007, p. 161; Grewe 2009, p. 429; Grewe 2010 2. ^ Ritti, Grewe & Kessener 2007, p. 140 3. ^ Ritti, Grewe & Kessener 2007, pp. 139-141 4. ^ Seigne 2002a; Seigne 2002b; Seigne 2002c 5. ^ Mangartz 2010; Ritti, Grewe & Kessener 2007, pp. 149-153 6. ^ Schioler 2009 7. ^ Wilson 2002, p. 16 8. ^ Ritti, Grewe & Kessener 2007, p. 161 9. ^ Ritti, Grewe & Kessener 2007, p. 156, fn. 74 Sources[edit] Roman sawmill at Hierapolis * Ritti, Tullia; Grewe, Klaus; Kessener, Paul (2007), "A Relief of a Water-powered Stone Saw Mill on a Sarcophagus at Hierapolis and its Implications", Journal of Roman Archaeology, vol. 20, pp. 138-163, doi:10.1017/S1047759400005341 * Grewe, Klaus (2009), "Die Reliefdarstellung einer antiken Steinsagemaschine aus Hierapolis in Phrygien und ihre Bedeutung fur die Technikgeschichte.
