On another occasion also, Colga, son of Cellach, asked and obtained from the saint a lump of salt which he had blessed, for the cure of his sister, who had nursed him, and was now suffering from a very severe attack of ophthalmia. This same sister and nurse having received such a blessed gift from the hand of her brother, hung it up on the wall over her bed; and after some days it happened by accident that a destructive fire entirely consumed the village where this took place, and with others the house of the aforesaid woman. Yet, strange to say, in order that the gift of the blessed man might not be destroyed, the portion of the wall from which it was suspended still stood uninjured after the rest of the house had been burned down; nor did the fire venture to touch even the two uprights from which the lump of salt was suspended.
