The people who carved these spirals and knots lived roughly between 500 BC and 400 AD and left behind no manual explaining themselves, which is why the meanings attached to Celtic symbols today rest on a mixture of later tradition, educated guesswork, and a good deal of invention. What recurs across the designs is a cluster of ideas around love, loyalty, energy, wisdom and war, and a fondness for the number three that runs through the triskelion’s conjoined spirals and the single unbroken line of the triquetra.

The symbols held incredibly meaningful powers in the lives of those living from approximately 500 B.C. to 400 A.D. 

Historically, we have very little to go on when attempting to grasp the true sense behind them. Many recurring themes in the meanings of Celtic symbols are love, loyalty, energy, wisdom, and war. 

We have created a list of some of the most well-known Celtic symbols to learn a little more about the language and their meaning.
