The Bad Popes

The Bad Popes is a 1969 book by E. R. Chamberlin that documents the lives of eight of the most controversial popes (papal years in parentheses):
 * Pope Stephen VI (896–897), who had his predecessor Pope Formosus exhumed, tried, de-fingered, briefly reburied, and thrown in the Tiber.
 * Pope John XII (955–964), who gave land to a mistress, murdered several people, and was killed by a man who caught him in bed with his wife.
 * Pope Benedict IX (1032–1044, 1045, 1047–1048), who "sold" the Papacy.
 * Pope Boniface VIII (1294–1303), who is lampooned in Dante's Divine Comedy.
 * Pope Urban VI (1378–1389), who complained that he did not hear enough screaming when Cardinals who had conspired against him were tortured.
 * Pope Alexander VI (1492–1503), a Borgia, who was guilty of nepotism and whose unattended corpse swelled until it could barely fit in a coffin.
 * Pope Leo X (1513–1521), a spendthrift member of the Medici family who once spent 1/7 of his predecessors' reserves on a single ceremony.
 * Pope Clement VII (1523–1534), also a Medici, whose power-politicking with France, Spain, and Germany got Rome sacked.
