[OIr., humming, purring, crooning; a performer of crónán, crooning, droning, humming, buzzing].
In the Fenian Cycle, an enormous, black, misshapen churl who comes unbidden to Fionn's hunting mound and reveals his destiny to him. He brought out two pipes ‘so that wounded men and women in travail would have fallen asleep at the exquisite music which he made’. When light fell upon Crónánach in the morning he was transformed so that he had the beauty, charm, and demeanour of a high king. (In early Irish law the singers of crónán were bond or slave musicians.)
