Sunwise, sunward or deasil (sometimes spelled deosil), are terms meaning to go clockwise or in the direction of the sun, as seen from the northern hemisphere. The opposite term is widdershins (Lowland Scots), or tuathal (Scottish Gaelic).[1] In Scottish culture, this turning direction is also considered auspicious, while the converse is true for counter-clockwise motion.
During the days of Gaelic Ireland and of the Irish clans, the Psalter known as Irish: An Cathach was used as both a rallying cry and protector in battle by the Chiefs of Clan O'Donnell. Before a battle it was customary for a chosen monk or holy man (usually attached to the Clan McGroarty and who was in a state of grace) to wear the Cathach and the cumdach, or book shrine, around his neck and then walk three times sunwise around the warriors of Clan O'Donnell.[2]
According to folklorist Kevin Danaher, on St. John's Eve in Ulster and Connaught, it was customary to light a bonfire at sunset and to walk sunwise around the fire while praying the rosary. Those who could not afford a rosary would keep tally by holding a small pebble during each prayer and throwing it into the bonfire as each prayer was completed.[3]
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 (diasil or deiseal) 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:
Wicca uses the spelling deosil, which violates the Gaelic orthography principle that a consonant must be surrounded by either broad vowels (a, o, u) or slender vowels (e, i). The Oxford English Dictionary gives precedence to the spelling "deasil", but also acknowledges "deiseal", "deisal", and "deisul".
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 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.
