between 30BC and 200 AD). The rulers of the Kushan Empire were perhaps the earliest to give themselves haloes on their coins, and the nimbus in art may have originated in Central Asia and spread both east and west. In Chinese and Japanese Buddhist art the halo has also been used since the earliest periods in depicting the image of Amitabha Buddha and others. Tibetan Buddhism uses haloes and aureoles of many types, drawing from both Indian and Chinese traditions, extensively in statues and Thangka paintings of Buddhist saints such as Milarepa and Padmasambhava and deities. Different coloured haloes have specific meanings: orange for monks, green for the Buddha and other more elevated beings, and commonly figures have both a halo for the head, and another circular one for the body, the two often intersecting somewhere around the head or neck. Thin lines of gold often radiate outwards or inwards from the rim of the halo, and sometimes a whole halo is made up of these. In India the head halo is called or , while the full body halo is . Elaborate haloes and especially aureoles also appear in Hindu sculpture, where they tend to develop into architectural frames in which the original idea can be hard to recognise. Theravada Buddhism and Jainism did not use the halo for many centuries, but later adopted it, though less thoroughly than other religious groups. In Asian art, the nimbus is often imagined as consisting not just of light, but of flames. This type seems to first appear in Chinese bronzes of which the earliest surviving examples date from before 450. The depiction of the flames may be very formalized, as in the regular little flames on the ring aureole surrounding many Chola bronzes and other classic Hindu sculptures of divinities, or very prominent, as with the more realistic flames, and sometimes smoke, shown rising to a peak behind many Tibetan Buddhist depictions of the "wrathful aspect" of divinities, and also in Persian miniatures of the classic period. Sometimes a thin line of flames rise up from the edges of a circular halo in Buddhist examples. In Tibetan paintings the flames are often shown as blown by a wind, usually from left to right. This type is also very rarely found, and on a smaller scale, in medieval Christian art. Halos are found in Islamic art from various places and periods, especially
