Their horses be heroes of darkness, horses of the shadow of death, horses of thick darkness, horses of fire, horses of blood, horses of hail, horses of iron, horses of fog. The horses upon which they ride stand beside mangers of fire full of coals of juniper and eat fiery coals from their mangers, [taking] a measure of forty bushel of coals in one mouthful. And the measure of the [content of the] mouth of such horse is [the content of] three mangers such as the mangers of Caesaraea, and the measure of each manger is the measure of the gate of Caesaraea.
