The story goes, that on one occasion a nun by the name of Brigid, a prioress of a convent in the area of the mouth of the river Fergus, wished to send a vestment to St. Senan. She had made the vestment for him herself. Brigid had no means of transporting the clothing to St. Senan, so she decided to pack it into a wicker basket, along with some hay, and to place the basket on the waters of the river Shannon. She hoped that the turning tide would convey the basket to St. Senan, in God’s name.
Brigid’s faith was not misplaced, the basket was carried down river by the tide and duly arrived on the shores of Inis Cathaigh/Scattery Island, where, the story goes, St. Senan received it as intended.
