The destruction of Da Derga's Hostel (Author: [unknown])

section 5

Then Cormac weds again his wife, even Étáin, and this was his desire, that the daughter of the woman who had before been abandoned i.e. his own daughter should be killed. So Cormac would not leave the girl to her mother to be nursed. Then his two thralls take her to a pit, and she smiles a laughing smile at them as they were putting her into it. Then their kindly nature came to them. They carry her into the calfshed of the cowherds of Etriscél, great-grandson of Iar, king of Tara, and they fostered her till she became a good embroideress; and there was not in Ireland a king's daughter dearer than she.
