Triscalia Designs
This Celtic knot sprang from the ancient spiral designs of the early Celts, originally found at places like Newgrange and Halstatt.
Three was a very powerful number to the Celts throughout Europe. This talisman shows the interaction of the threefold path. Whichever way you want to see things, it can be divided into three's. The three of Cups, Father Son and Holy Ghost; Maid Mother Crone; Past present, and future; me, my wife, and our dog, or any way you cut it, they all fold together in the Cosmos to express the whole.
Although many knots could be termed an "Eternity Knot", any knot that has a closed path, with no beginning or end may be symbolic of continuum or eternity. Since knot work is often used as an emblem of heritage, the symbolism of "continuum" reinforces the endurance of the tradition.
The Tri-fold structure of the triscalia /triskalia/trefoil/triquetra knot is universal in Celtic cultures across Europe. The three points suggest the coming together of past, present, and future.
