Ireland’s three dragon sisters Dabran, Farbagh, and Cathach were the offspring of the gatekeeper of Hell and the all-devouring sow; they were nursed by the red demon of West Ireland. Cathach, the youngest of the three, made her home on Inis Cathaig (now Scattery Island).
A horrible sight she was to see, a great dragon bigger a small isle, with a back like a round island covered with scales and shells. A rough bristly mane like a boar’s covered her foreparts. When she opened her cavernous mouth filled with a double row of sharp teeth, her entrails could be seen. A cruel eye gleamed in her head. Her body stood on two short, thick, hairy legs armed with iron nails that struck sparks on the rocks as she moved. Her belly was like a furnace. The tail of a whale she had, a tail with iron claws on it that ploughed furrows in the ground behind her. Cathach could move on land and swim with equal ease, and the sea boiled around her.
Dabran and Farbagh were both slain by Crohan, Sal, and Daltheen, the three sons of Toraliv M’Stairn. When Cathach sensed the loss of her siblings, she went on a rampage, laying waste to the lands around the Shannon Estuary from Limerick to the sea, sinking ships and paralyzing commerce for a year. When the three brothers returned and saw the destruction wreaked by Cathach, they were so distraught that they flung themselves into the sea to their deaths.
Cathach herself was defeated by a far more humble and unassuming hero. When Saint Senan made landfall on Inis Cathaig, Cathach prepared to devour him whole. But the holy man made the sign of the cross in front of her face, and she was quieted. “In the name of the Father, the Son, and the Holy Ghost, leave this island, and hurt no one here or wherever you leave to”. And Cathach did as she was told. She disappeared into the estuary and went to Sliab Collain without harming anyone; and if she is still alive, she has remained obedient to Senan’s command.
The ruins of the church of Saint Senan can still be seen to this day on Scattery Island.
