Encyclopedia entry

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.
