Slieve Gullion appears in
Irish mythology.
Fionn and the Cailleach In the tale known as
The Hunt of Slieve Gullion,
Áine and her sister Milucra both seek after the legendary hero
Fionn mac Cumhaill (Finn McCool). Knowing that Áine vowed never to marry a man with grey hair, Milucra secretly puts a spell on the lake atop Slieve Gullion, so that anyone who swam in it would become elderly. She tricks Fionn by asking him to fetch her golden ring from the lake, and he emerges as an old man with grey-white hair. His men, the
Fianna, force her to give him a restorative potion from her
cornucopia. Fionn's youth returns, but his hair does not return to its true colour. This is said to be the origin of his name, Fionn, meaning 'white'. In some versions of the tale, Milucra is revealed to be the
Cailleach Bhéara (Calliagh Birra), an ancient goddess. The names of several features on the mountain refer to the Cailleach Bhéara. The passage grave is known locally as Calliagh Birra's House and the small lake is called Calliagh Birra's Lough. Lower down, on a hillock called Spellick, is a rock feature called the Calliagh Birra's Chair. Locals would visit it at
Lughnasadh and take turns sitting on the chair.
Cú Chulainn Slieve Gullion is said to be where the legendary hero
Cú Chulainn (Cuhullin) received his name and where he spent his childhood as Sétanta. According to myth, the mountain is named after
Culann the
metalsmith. Culann invites
Conchobhar mac Neasa, king of Ulster, to a feast at his house on the slopes of Slieve Gullion. On his way, Conchobhar stops at the playing field to watch the boys play
hurling. He is so impressed by Sétanta's performance that he asks him to join him at the feast. Sétanta promises to join him after he finishes his game. Conchobhar goes ahead, but he forgets about Sétanta, and Culann lets loose his ferocious hound to guard his house. When Sétanta arrives, the hound attacks him, but he kills it; in one version by smashing it against a standing stone, in another by driving a
sliotar (hurling ball) down its throat with his
hurley. Culann is devastated by the loss of his hound, so Sétanta promises to rear him a replacement, and until it was old enough to do the job, he himself would guard Culann's house. The druid
Cathbhadh announces that his name henceforth would be Cú Chulainn, "Culann's Hound". In the
Táin Bó Cuailnge, the nearby
Gap of the North is where Cú Chulainn single-handedly fends-off the army of queen
Méabh. ==See also==
