That the idea of the revelation as described by Smith in his autobiography was not original is shown by the fact that a similar divine message, engraved on plates, was announced to have been received from an angel nearly six hundred years before the alleged visit of an angel to Smith. These original plates were described as of copper, and the recipient was a monk named Cyril, from whom their contents passed into the possession of the Abbot Joachim, whose "Everlasting Gospel," founded thereon, was offered to the church as supplanting the New Testament, just as the New Testament had supplanted the Old, and caused so serious a schism that Pope Alexander IV took the severest measures against it.* * Draper's "Intellectual Development of Europe," Vol. II, Chap. III. For an exhaustive essay on the "Everlasting Gospel," by Renan, see Revue des Deux Mondes, June, 1866. For John of Parma's part in the Gospel, see "Histoire Litteraire de la France" (1842), Vol. XX, p. 24. The evidence that the history of the "Everlasting Gospel" of the thirteenth century supplied the idea of the Mormon Bible lies not only in the resemblance between the celestial announcement of both, but in the fact that both were declared to have the same important purport--as a forerunner of the end of the world--and that the name "Everlasting Gospel" was adopted and constantly used in connection with their message by the original leaders in the Mormon church. If it is asked, How could Rigdon become acquainted with the story of the original "Everlasting Gospel," the answer is that it was just such subjects that would most attract his attention, and that his studies had led him into directions where the story of Cyril's plates would probably have been mentioned. He was a student of every subject out of which he could evolve a sect, from the time of his Pittsburg pastorate. Hepworth Dixon said, "He knew the writings of Maham, Gates, and Boyle, writings in which love and marriage are considered in relation to Gospel liberty and the future life."* H. H. Bancroft, noting his appointment as Professor of Church History in Nauvoo University, speaks of him as "versed in history, belles-lettres, and oratory."** Mrs. James A. Garfield told Mrs. Dickenson that Rigdon taught her father Latin and Greek.*** David Whitmer, who was so intimately acquainted with the early history of the church, testified: "Rigdon was a thorough biblical scholar, a man of fine education and a powerful orator."**** A writer, describing Rigdon while the church was at Nauvoo, said, "There is no divine in the West more learned in biblical literature and the history of the world than he."***** All this indicates that a knowledge of the earlier "Everlasting Gospel" was easily within Rigdon's reach. We may even surmise the exact source of this knowledge. Mosheim's "Ecclesiastical History, Ancient and Modern" was at his disposal. Editions of it had appeared in London in 1765, 1768, 1774, 1782, 1790,
