Sunwise


In Scottish folklore, sunwise, deosil or sunward was considered the “prosperous course”, turning from east to west in the direction of the sun. The opposite course, counterclockwise, was known as widdershins, or tuathal. In the Northern Hemisphere, "sunwise" and "clockwise" run in the same direction, because sundials were used to tell time, and their features were transferred to clock faces. Another influence may have been the right-handed bias in many cultures.

Scottish culture

This is descriptive of the ceremony observed by the druids, of walking round their temples by the south, in the course of their directions, always keeping their temples on their right. This course was deemed propitious, while the contrary course is perceived as fatal, or at least unpropitious. From this ancient superstition are derived several Gaelic customs which were still observed around the turn of the twentieth century, such as drinking over the left thumb, as Toland expresses it, or according to the course of the sun.
Martin Martin says:

"Deosil" and other spellings

uses the spelling deosil, which violates the Gaelic orthography principle that a consonant must be surrounded by either broad vowels or slender vowels. The Oxford English Dictionary gives precedence to the spelling "deasil", but also acknowledges "deiseal", "deisal", and "deisul".

Other cultures

This distinction exists in traditional Tibetan religion. Tibetan Buddhists go round their shrines sunwise, but followers of Bonpo go widdershins. The former consider Bonpo to be merely a perversion of their practice, but as Bonpo adherents claim that their religion as the indigenous one of Tibet was doing this prior to the arrival of Buddhism in the country.
The Hindu pradakshina, the auspicious circumambulation of a temple, is also made clockwise.
A similar preference may inform the left-hand drive found in England, India, and Japan. Any temple or shrine in the middle of a road must be passed to its left.
