Araghatta, also known as the 'Persian wheel' or 'Norias', was a device used in medieval India for lifting water from wells or rivers for irrigation purposes. It typically consisted of a large wheel fitted with pots or buckets along its circumference. As the wheel rotated, the pots would fill with water from a water source and then empty into a trough, channel, or aqueduct for distribution to fields or other areas requiring irrigation.
