¶1] Mag Etrige, whence the name? Not hard to say. When this plain was being cleared and ploughed by Partholan, one of the four oxen that were ploughing it for him died there through the greatness of its exertions. Its name was Etrige, and from it the plain is called Mag Etrige, as the poet has said:
¶2] Liag and Lecmag with his sheen, Imaire and Etrige, were the team of four oxen, with the right of companies, who ploughed Partholan's land.
