Isabel Mac Eachainn said that a widow woman at Tabal, Mull, had a cow ill with the tarbhan (swelling from surfeit), and she was wringing her hands and beating her breast to see her beloved cow in pain. At that moment she saw Calum Cille, Columba, and his twelve disciples in their curachan (little boat or coracle), rowing home to Iona. The widow ran down to the rudha (point) and hailed Calum Cille, and asked him to heal her cow. Calum Cille never turned a dull ear to the poor, to the penitent, to the distressed, and he came ashore and made the ora to the white cow, and the white cow rose upon her feet and shook herself and began to browse upon the green grass before her.
Go thou home, bronag, and have faith in the God who made thee and in Christ the Saviour who loved thee and died for thee, and in thine own self, and all will go well with thee and with thy cow.
Having said this, Calum Cille rejoined his followers in the curachan and resumed his journey to Hi. There was no one like Calum Cille, no one, my dear. He was big and handsome and eloquent, haughty to the over-haughty and humble to the humble, kind to the weak and wounded.
