Cath Maige Tuired: The Second Battle of Mag Tuired (Author: [unknown])

section 80

Then Figol mac Mámois, their druid, said, ‘Three showers of fire will be rained upon the faces of the Fomorian host, and I will take out of them two-thirds of their courage and their skill at arms and their strength, and I will bind their urine in their own bodies and in the bodies of their horses. Every breath that the men of Ireland will exhale will increase their courage and skill at arms and strength. Even if they remain in battle for seven years, they will not be weary at all.’
