Although there is evidence that there were Norias around the city during the Byzantine era which ended in 1453, the Norias of Hama date from the a little later. It is thought that they were started in the Ayyubid dynasty in around the twelfth century and enlarged in the Mamluk era of the fourteenth.
It was at this point that the Mamluk reconditioned, increased and enlarged the amount of Noria in the city as their influence grew. At one point in what we call the medieval era there were over thirty waterwheels in the city which took water from the Orontes river. The city must have seemed like a metropolitan oasis.
Using gravity, the water then flows through aqueduct channels to either households or farms in the vicinity. Just as math was used in the construction of the waterwheels so it was in working out the times at which people had access to the water. As a precious commodity it was important that it was shared fairly.
There are no other mechanical processes involved in the purpose of a noria – the power it produces is not used to run a mill for example. The undershot of the wheel has a rim consisting of a number of containers and they lift the water upwards. Conceptually it is similar to the hydraulic ram.
The largest noria in Hama is the al-Mohamadiyya, the purpose of which was to supply the city’s Great Mosque with water and its aqueduct is still there – or at least part of it - it does end rather abruptly about one hundred meters away from the noria. Work started on this greatest of the wheels in the fourteenth century, at about the same time as Dante wrote The Inferno. It is the largest noria in the world.
The noria of Hama were almost industrial in their capacity. The largest has 120 water collectors and was capable of delivering almost one hundred liters of water each minute to the aqueduct. Although none of the larger noria are now in use they are being maintained by the Syrian government so that future generations can witness the ingenuity of centuries gone by for themselves.
