A fly whisk is a common item found in Asia and the Middle East. Similar to a fan, a fly whisk is made of anything that is relatively light in weight to hold that can be moved by the hand to create a disturbance in the air and prevent flies from landing or flying to close to the face, food or a holy object such as a sculpture. Indian and Middle Eastern fly whisks of some quality were traditionally made from bleached yak tails exported from Tibet and the high Himalayas.
Early Gandharan sculpture can be found where retinue figures accompanying the Buddha are holding a fly whisk. In early metal works from the Swat Valley, Gupta and Pala India bodhisattvas can be found standing to the right and left of the Buddha holding a fly whisk.
In later Tibetan paintings there are three arhat/sthavira, Angaja, Vanavasin and Vajriputra along with one attendant, Dharmatala, that are depicted, based on an early text of praise, holding a fly whisk.
