Sawmill
The Hierapolis
sawmill, a Roman water-powered stone saw mill at Hierapolis, Asia Minor
(modern-day Turkey) dating to the second half of the 3rd century AD is the
earliest sawmill. It is also the earliest known machine to incorporate a crank
and connecting rod mechanism. Water-powered stone sawmills working with cranks
and connecting rods, but without gear train, are archaeologically attested for
the 6th century AD at the Eastern Roman cities Gerasa and Ephesus. The earliest
literary reference to a working sawmill comes from a Roman poet, Ausonius who
wrote an epic poem about the river Moselle in Germany in the late 4th century
AD. At one point in the poem he describes the shrieking sound of a watermill
cutting marble. Marble sawmills also seem to be indicated by the Christian
saint Gregory of Nyssa from Anatolia around 370/390 AD, demonstrating a
diversified use of water-power in many parts of the Roman Empire.
