Celtic love knotsThis stands for the love between two people, depicted by interlaced knots. Lovers exchange these knots just as couples exchange rings these days. The Celtic Oval knot is the simplest of all Celtic love knots. It stands for eternal life and goes back to 2500 BCE when the early Scottish, Welsh and Irish Celts first devised these knots.
There are many other Celtic knots too, each for a different purpose—after all, these knots speak for an entire civilization.
