What is the witch's knot symbol?

[lahh Kali]

Is it a variation of the triskele? Can it be used?

 

[Kouros Aionios]

This "Witch's Knot" is a Ancient Celtic Symbol that symbolizes the Four Cardinal Directions, the Four Elements, and the interconnectedness and eternal nature of the Kosmos. This symbol is not really a variation of the Triskele; it is quite different. The Triquetra is more related to the Triskele.
