CALLING THE QUARTERS

We all know how to do this, Lords of the Watchtowers, East is Air, South is Fire, West is Water, North is Earth. Well No !
That is the recognised Wiccan way of doing it. There are plenty of other methods or you can create your own (remember, all that matters is that it works for you). I'll give you some samples as a guide.
Wiccans start facing East and move clockwise (Deosil), many others start in the North and move clockwise, whilst others move counter-clockwise (Widdershins).
West is nearly always Water but it's common for East to be Fire (where the Sun comes up), North to be Air (the cold north winds) leaving South to be Earth.

Perhaps you don't wish to call the Lords of the Watch Towers, that's OK, there are plenty of other options.
ANGELS........East - Raphael, South - Michael, West - Gabriel, North - Uriel.
WIND GODS.....East - Eurus, South - Notus, West - Zephyrus, North - Boreas.

Or you can call in relation to the Elements rather than Directions.
ELEMENTALS....Air - Sylphs, Fire - Salamanders, Water - Undines, Earth - Gnomes.
DRAGONS.......Air - Sairys, Fire - Fafnir, Water - Naelyon, Earth - Grael.
ALCHEMY.......Air - Winged Human, Fire - Lion, Water - Eagle, Earth - Winged Bull.

There are probably plenty of other options that you can explore from different mythologies.

It is also a good idea to be aware of your local area and adapt accordingly. I live in Essex and have the North Sea to the east, so I use the following ritual

East - Water
"In the name of the Lady, and in my own name,
I claim this circle as a place of Men.
Let all who enter be bound to speak, and hear the Truth.
So shall it be."

South - Fire
"In the name of the Lord of the Greenwood, and in my own name,
I claim this circle as a place of Nature
Let all who enter be bound to the sacred web of life.
So shall it be."

West - Earth
"In the name of the Lord, and in my own name,
I claim this circle as a place of Women.
Let all who enter be bound to Perfect Love and Perfect Trust.
So shall it be."

North - Air
"In the name of the Queen of Heaven, and in my own name,
I claim this circle as Sacred Space.
Let all who enter be opened to the presence of God and Goddess.
So shall it be."
