Triquetra

A triquetra is a symbol made up of three connected circles. It looks like three overlapping circles that are all treated like one shape. The symbolic meaning of a triquetra can vary, but it is often associated with the idea of a trinity - for example, the Christian Trinity of the Father, Son and Holy Spirit. This symbol is also seen as a protective symbol, an emblem to ward off bad luck or evil. In many cultures, it is a sign of the power of three - something that is made stronger when combined.
