Contemporary with Callistus, the saint and martyr, was Hippolytus, the scholar and saint and martyr. They were the two shining jewels of the Roman Church. The many works of Hippolytus had strangely disappeared, and tradition was not even sure of which town he had been Bishop; but there was evidence enough to connect him with the Roman Church and to justify the claim that he was the Origen of the West. When, in 1551, a broken marble statue of Hippolytus was discovered at Rome, it was devoutly restored and set up in the Lateran Museum. And just three hundred years afterwards, in 1851, there was given to the world a lost work of the saintly scholar, from which it is plain that he was the first Anti-Pope, and that the Pope whom he opposed and reviled was Callistus. The first book of this work, the _Refutation of all Heresies_ (sometimes called the _Philosophoumena_), had long been known; the manuscript copy of Books IV. to X. was found in a monastery on Mount Athos in 1842. Now that the true character of Hippolytus is known, some doubt has been cast upon his scholarship, but it was considerable for his age and environment. He was one of the very few scholars of the Roman Church during several centuries, and one chapter of his work throws an interesting light on the person of Callistus and on a remarkable phase of the development of the Papacy. The controversy about the authorship of the book and about the charges against Callistus has brought to bear upon that period all the available light; and the modern student will probably find the truth somewhere between the extremes held by the contending historians of the nineteenth century.[16] De Rossi himself, indeed, while pretending to support, entirely discredits the arguments with which Döllinger, in his years of orthodoxy, sought to defend the impeccability of the Popes and to prove the moral obliquity of all who opposed them. The Italian archæologist, it is true, imputes to Hippolytus a malice which goes ill with _his_ reputation for sanctity, but perhaps we shall be able to extricate ourselves from this painful dilemma without grave detriment to the character of either saint.
