Caladbolg

FERGUS MAC ROICH

IRISH MYTHS AND LEGENDS

Queen Medb, Fergus’ lover

Fergus mac Roich, King of Ulster, was well-known for his sexual prowess. His 'feats' are described in the Ulster Cycle. Even Caladbolg, his two-handed greatsword, means ‘hard cleft’ in Middle Welsh. The sword is said to produce a rainbow when swung. 

While Fergus was formidable, his lust would get him into all sorts of trouble. During his reign of Ulster, he desired Nessa, a beautiful princess. A shrewd woman, Nessa agreed — provided he briefly his kingship to her son, Conchobar mac Nessa, for a time. Of course, Fergus agreed. Unfortunately, Conchobar ended up doing a better job and took over the position permanently. 

Fergus handled the matter stoically. For the prosperity of Ulster, he had no qualms about serving under a better king. Alas, Conchobar wasn't satisfied with that — and tried to kill him. Fergus escaped, but Fiachu, his son, wasn't so lucky. Fergus was devastated. In his bid for revenge, he took Caladbolg and defected to Connacht, led by Queen Medb and King Ailill mac Mata. 

Caladbolg, a representation

Medb was as oversexed as Fergus. As such, it wasn't surprising that the two of them would become lovers. However, Ailill learnt of the affair while they were on an expedition to claim Ulster's prized stud bull. Furious, he ordered his men to steal Caladbolg while Fergus was 'busy' with Medb. 

Unfortunately, with Fergus facing Conchobar, Ailill had to return Caladbolg. A fierce battle ensued. Fergus was about to kill Conchobar when he was stopped by Cormac Cond Longas, Conchobar’s eldest son — and Fergus’ foster son. Fergus was touched by Cormac’s plea, but the thought of leaving his foe alive filled him with such rage that he unleashed three slashes with Caladbolg, destroying three hills.
