In the casting of a magic circle, the four cardinal elements are visualised as contributing their influence from the four cardinal directions: Air in the east, Fire in the south, Water in the west and Earth in the north. There may be variations between groups though, particularly in the Southern Hemisphere, since these attributions are symbolic of (amongst other things) the path of the sun through the daytime sky. For example, in southern latitudes the sun reaches its hottest point in the northern part of the sky, and north is the direction of the Tropics, so this is commonly the direction given to Fire.
