According to local traditions the first inhabitant on Sliab an Iarainn was a woman who came to Ireland many years before the Deluge.
This mysterious individual is supposed to have been accompanied by forty men on the journey to the mountain.
Fatigued by the long journey she fell asleep. During her sleep the Deluge came and destroyed every living thing. When she awoke she found herself hungry and alone and in her sorrow and desperation she lifted her wings and flew away from Ireland.
