Celtic knots (aka mystic knot, endless knot) work really well as a tattoo design or part of a tattoo. The symbolic meaning of Celtic knots is not really clear, although some people attribute magical powers to the knots.
For me, Celtic knot tattoos symbolize eternity because the lines of the knotwork form an endless loop, without a beginning or an end.
The Celtic trinity knot is a very simple, but powerful symbol and very suitable for a tattoo. It is a triangle knot, the 3 corners have various meanings:
