Sergius IV, POPE, date of birth unknown; consecrated about July 31, 1009; d. May 12, 1012. Peter Pig’s Snout (Bucca Porci) was the son of Peter the shoemaker, of the ninth region of Rome (Pina), and before he became Sergius IV had been bishop of Albano (1004-9). He checked the power of the Patricius, John Crescentius, who dominated Rome by strengthening the party in favor of the Germans. Little is known of the doings of Sergius except that by grants of privilege, the papyrus originals of some of which still exist, he exempted several monasteries from episcopal jurisdiction. Though his own temporal power was small, various nobles placed their lands under his protection. He showed himself a great friend of the poor in a time of famine, and was buried in the Lateran Bascilica.
