In Search of Ancient Heroes
Early War-Gods and Warriors

Descriptions of Celtic feasts contain accounts of contests of strength and 'mock battles', some of which appear to have been frightening in their intensity. An air of competition existing within the fragmented society of the Celtic world came to the fore during such gatherings. It was a mark of honour for a tribe to boast the best warrior in the region and he was usually accorded special status.

[Celtic war gods gave power to certain weapons, but also to several of the ancient heroes, whose devotion found expression in the devastating 'riastradh' or war-spasm]

A frightening description of the warrior in a state of riastradh is described in the great Irish epic, the Táin Bó Cuailnge - The Cattle Raid of Cooley. He shakes from head to toe and revolves within his skin that becomes red and hot to touch. His features become bestial - one eye becoming large and bloodshot while the other becomes extremely small and menacing. His mouth becomes impossibly large and emits both fire and sparks, while his hair becomes spiked and emits further flame. The 'warrior light' shines on his brow, temporarily blinding all that come near him. In this state, he is uncontrollable but also invincible. He seems to be little more than a magical killing machine that cannot be harmed. When the riastradh has abated, Cú Chulainn is left drained and weakened.
