The Wooing of Emer by Cú Chulainn (Author: [unknown])

paragraph 53

‘When she said: ‘No one comes to this plain, who does not kill as many as argat,’ viz. argat in the language of the poets means 'a hundred'; that is the interpretation, and this is what it means, that it is not easy to carry off the maiden, unless I slay a hundred men at each ford from Ailbine to the Boyne, together with Scennmenn the Wily, the sister of her father, who will change herself into every shape there, to destroy my chariot and to bring about my death,’ said Cuchulaind.
