Cailitin

Cailitín Dána (Cailitin or Calatin) was the chief druid of Medb and Ailill. Cailitin was known most for his fight against Ulster's hero Cu Chulainn, in the Táin Bó Cuailnge.

Cailitin had many sons and several daughters, and they were all known as the Clan Cailitin. They were all described as hideously deformed druids.

Twenty-seven sons joined Cailitín when they crossed over to Ulster with the large army of Medb. Just before the single combat between Cu Chulainn and Fer Díad Mac Damann, Calitin and his sons fought an unfair combat against the Ulsterian hero. Actually, 29 of them fought against Cu Chulainn, and one of them was named Glas Mac Delga, who was either Cailitin's grandson or nephew (sister's son).

The Clan Cailitin wielded 29 poison-tipped spears; if the victim was killed outright, they would die from the poison after nine days of agony. Cu Chulainn caught all 29 spears with his shield, but their superior numbers would have killed the hero, had not one of the exiled Ulstermen, Fiachu Mac Fir Fhebe, come to his aid. With one sword stroke, Fiachu sheared off the right arms of Clan Cailitin. Cu Chulainn killed all the Clan Cailitin, though Glas managed to momentarily escape back to Medb's camp. Before Glas could disclose the treachery of Fiachu, Cailitin's nephew was killed by a slingstone of Cu Chulainn.

Despite the death of Cailitin and his 27 sons, Cailitin's other surviving children became involved with Cu Chulainn's death. They used their magic to lure the hero away, alone again, to face Medb's army.
