Deosil/Widdershins

Deosil is generally taken to mean clockwise, and Widdershins to mean anticlockwise. These two meanings are taken from the Northern Hemisphere, where the words originated. However we need to go back to the 'real' meanings of both words, not just what they have come to mean.

Deosil means 'with the sun'. In the Northern Hemisphere the sun travels in a 'clockwise' arc across the sky, that is it goes East-South-West. However in the Southern Hemisphere, the sun travels in an 'anticlockwise' arc across the sky, that is East-North-West. Therefore Deosil for the Southern Hemisphere is in fact anticlockwise.

Similarly, Widdershins means 'against the sun', and for the reasons just described, in the Southern Hemisphere that's actually clockwise.
