- The stream of Time, irresistible, ever moving, carries off and bears away all things that come to birth and plunges them into utter darkness, both deeds of no account and deeds which are mighty and worthy of commemoration; as the playwright [Sophocles] says, it 'brings to light that which was unseen and shrouds from us that which was manifest.' Nevertheless, the science of History is a great bulwark against this stream of Time; in a way it checks this irresistible flood, it holds in a tight grasp whatever it can seize floating on the surface and will not allow it to slip away into the depths of Oblivion.

- Even now I cannot believe that I am still alive and writing this account of the emperor's death. I put my hands to my eyes, wondering if what I am relating here is not all a dream - or maybe it is not a dream: perhaps it is a delusion and I am mad, the victim of some extraordinary and monstrous hallucination. How comes it that when he is dead I am still numbered among the living?
- One such was that braggart Robert, notorious for his power-lust, born in Normandy, but nursed and nourished by manifold Evil.

- Constantine was Nature's masterpiece, a triumph, as it were, of God's handiwork. One look at him would convince anyone that here was a descendant of the mythical Golden Age of the Greeks, so infinite was his charm.
- While the abominable pope with his spiritual peace and evangelic peace, this despot, marched to make war on his own kindred with might and main - the man of peace, too, and disciple of the Man of Peace!
- Of Pope Gregory VII
