Cuchulainn
The heroic tales of Cuchulainn are so old that they were almost forgotten when they were revived by 7th century bard named Sechan Torpeist.
Cuchulainn was born Setanta, but changed his name when he placed a geis upon himself after accidentily killing the watchdog of the smith Culann. He vowed to take the place of the dog, guarding the pass into Ulster, and thus became known as the Hound of Culann. Several women in Celtic myth are said to be his mother, some human and other divine. The god Lugh is sometimes also mentioned as his father, but this relationship appears to be more of a spiritual link than a biological one. Cuchulainn's human father is Sualtam.

He studied under the warrior goddess Scathach on the Isle of Shadow and returned to Ulster to be a great warrior and leader of the Red Branch, a semi-chivalrous order of warriors of Ulster whose exploits make up an entire cycle in Irish mythology. He became semi-divine himself through his adventures and is now honored as a pagan god.

Many of his stories are recorded at length in The Book of the Dun Cow. A statue in Dublin portrays his dramatic demise in battle when, while his men were asleep, he held off Maeve's armies single-handedly by being tied to a tree to remain standing. Cuchlainn's image may have once been that of a minor sun or sacrificial god. His great enemy, the sovereign Queen Maeve of Connacht, seemed ready to replace her husband with Cuchulainn who resisted the sacrificial role and battled her instead. Predictably, she won the war and his blood was spilled on the earth in the manner of the sacrificial gods. During his death battle he failed to recognize the Morrigan flying over him, and many believe that was what really killed him -- failure to realize the role he was born to play as symbolized by the death-bird in ages of the triple crone.

He had many lovers including Aife, Emer, and 'the faery woman' Fand.
