The hydraulic wheel of Perachora

Reconstruction of an ancient greek mechanism of the 3rd century B.C., used as a water pump (it is the most ancient pumping device in Europe), remains of which were found by Tomlinson during excavations at Perachora Korinthias.

It consisted of a large perpendicular wheel, bearing bronze or clay containers, which rotated with the help of animals through two wooden cogwheels vertically connected. The containers filled with water at the lower point of the wheel and subsequently tipped over to a tailrace at the higher point of the conduit.
