This account of Italian prisons must now revert to a much earlier date, when the so-called crime of religious error moved the supreme authority to establish a special tribunal to cope with it, having extensive penal powers. In other words, the Inquisition was created. Toward the end of the twelfth century the popes had consolidated their spiritual dominion in Christendom and aimed at complete temporal sway; the papal authority was recognised by kings, bishops, clergy and the laity of all degrees; the holy father claimed the power to forgive sins and the right to punish sinners. The popes had achieved by perseverance and astute diplomacy a paramount position; they ruled wide territories in Italy and enjoyed princely revenues gathered in from all sources. They aspired now to impose orthodoxy of belief, feeling that dissent from established forms might lead to resistance and rebellion against papal supremacy and the authority of the Church. Heresy was the beginning of treason; it must be sought out unceasingly and sternly repressed. The principles of the Reformation were foreshadowed long before its birth, and already brave men dared to worship in their own way and claimed independence of religious belief. The extirpation of heresy among the Albigenses, the Waldenses, and the Patarines[3] was the avowed object of the cruel measures of the originator of the Inquisition, Pope Innocent III, and of the religious persecutions which for centuries decimated and disgraced Christendom. Innocent III, who was of the family of the Conti, became pope in 1198. Historians of his own way of thinking speak of him in terms of almost fulsome eulogy. He is described as, “a man of clear understanding and retentive memory; he excelled in divine and human learning, spoke well in common Italian and in Latin, sang songs and psalms well, was of middle stature and commanding aspect. He preserved the mean between prodigality and avarice; but gave away alms and food liberally, although sparing in other respects, except in cases of necessity. Severe toward the rebellious and contumacious, but kind to the humble and devout; brave and constant, magnanimous and astute; a defender of the faith and an assailant of heresy; in justice rigid, and in mercy pious; humble in prosperity, and patient in adversity; in temper somewhat irascible, yet easily forgiving.”
