By the sacred earth on which I kneel, by the shades that wander near me, by the deep and eternal grief that I feel, I swear; and by thee, O Night, and by the spirits that preside over thee, I swear to pursue the daemon, who caused this misery, until he or I shall perish in mortal conflict. For this purpose I will preserve my life; to execute this dear revenge, will I again behold the sun, and tread the green herbage of earth, which otherwise should vanish from my eyes for ever. And I call on you, spirits of the dead:; on on you, wandering ministers of vengeance, to aid and conduct me in my work. Let the cursed and hellish monster drink deep of agony; let him feel the despair that now torments me
