Chapter XXXI: How Ciaran Floated a Firebrand on the Lake (lb)

_The Harbour of the Island._--It must be remembered, in reading this and other island stories, that as a rule "the harbour of the island" is not, as might be expected, the landing-stage on the island itself, but the port on the mainland from which ships depart to visit the island. Thus Portraine, a place on the coast north of Dublin, is properly _Port Rachrann_, the Port of Rachra--the port from which voyagers sailed to Rachra, the island now called by its Norse name Lambay.

_Parallels._--I have not found an exact parallel, but the story belongs to the same family as that related of Coemgen, who kindled a fire with the drops of water that fell from his fingers after washing his hands (CS, 839).
