Amiens - BM - ms. 0483, detail of f. 189v. William of Tyre, Le Livre d’Eracles. Northern France, 1440-1445.
“Regardless of treaties and the many services which our people had rendered to the empire, the Greeks seized all those who appeared capable of resistance, set fire to their houses, and speedily reduced the entire quarter to ashes. Women and children, the aged and the sick, all alike perished in the flames. To vent their rage upon secular buildings alone, however, was far from satisfying their unholy wickedness; they also set fire to churches and venerated places of every description and burned, together with the sacred edifices, those who had fled thither for refuge. No distinction between clergy and laymen, except that greater fury was displayed toward those who wore the honorable habits of high office or religion. Monks and priests were the especial victims of their madness and were put to death under excruciating torture. Among these latter was a venerable man named John, a subdeacon of the holy Roman church, whom the pope had sent to Constantinople on business relating to the church. They seized him and, cutting off his head, fastened it to the tail of a filthy dog as an insult to the church. In the midst of such frightful sacrilege, worse than parricide, not even the dead, whom impiety itself generally spares, were suffered to rest undisturbed. Corpses were torn from the tombs and dragged through the streets and squares as if the insensate bodies were capable of feeling the indignities offered them.” - William of Tyre, A History of Deeds Done Beyond the Sea, describing events of 1182. From the E.A. Babcock translation (Columbia, 1943)
