Lugh, or Lug, was the sun god of the Irish Celts. One of his
weapons was a rod-sling which worshippers sometimes saw in
the sky as a rainbow. As a tribal god, he was particularly
skilled in the use of his massive, invincible spear, which
fought on its own accord. One of his epithets is _lamfhada_
(of the long arm). He was a young and apparently more
attractive deity than Dagda, the father of the gods. Being
able to shapeshift, his name translates as lynx.
