In Irish mythology the father of Lugh (who was the father
of the Ulster warrior-hero Cuchulain). Kian had a magic cow
with a wonderful supply of milk. After the cow was stolen by
Balor (king of the Fomorians), Kian took revenge by making
Balors daughter, Ethlinn, the mother of three sons. Two were
drowned by Balor, and the third, Lugh, escaped by falling into
a bay and being wafted back to his father, Kian.
Some years later while fighting in Ulster, Kian encountered
the three sons of Turenn, whose house was at enmity with his.
To escape their notice, he turned himself into a pig, but they
recognized him and one of them wounded him. He begged to
be allowed to restore himself to his human form before dying.
This request was granted, and Kian rejoiced in having outwitted
his enemies; they would have to pay the blood fine for a
man instead of a pig. The brothers, determined that there
should be no bloodstained weapon as evidence of the deed,
stoned Kian and buried his body.
