The ancient Celts had no written word, nor did they need it. Instead they symbolized their world in ways that were easily understood by all. Apart from symbolizing relationships, they represented the things in the world around them in their symbols too. However more personal relationships within tribes were symbolized by means of designs or shapes which is today considered a form of artwork.

The Celts used symbols to communicate to each other particular meanings, but also used them to illustrate their spirituality or as a means of projecting an image to another. Celtic warriors decorated their bodies in battle with symbols they deemed most appropriate individually, yet their body art had a twofold reasoning behind it.

The first reasoning was personal while the second was meant to instil fear in their enemies. For instance, warriors might decorate their bodies with a particular animal that they hoped to gain the powers of in battle. They might also use symbols that indicated brotherhood, a bond that existed between each warrior on the battlefield. Many symbols used called on the Gods and Goddesses to bestow protection, power and courage.
