In response to the question, “How and where did you obtain the Book of Mormon?” Joseph Smith responded: “Moroni, who deposited the plates in a hill in Manchester, Ontario county, New York, being dead and raised again therefrom, appeared unto me, and told me where they were, and gave me directions how to obtain them. I obtained them, and the Urim and Thummim with them, by the means of which I translated the plates; and thus came the Book of Mormon.”3

“I was [told by Moroni] where were deposited some plates on which were engraven an abridgment of the records of the ancient Prophets that had existed on this continent. … These records were engraven on plates which had the appearance of gold; each plate was six inches wide and eight inches long, and not quite so thick as common tin. They were filled with engravings, in Egyptian characters, and bound together in a volume as the leaves of a book, with three rings running through the whole. The volume was something near six inches in thickness, a part of which was sealed. The characters on the unsealed part were small, and beautifully engraved. The whole book exhibited many marks of antiquity in its construction, and much skill in the art of engraving. With the records was found a curious instrument, which the ancients called ‘Urim and Thummim,’ which consisted of two transparent stones set in the rim of a bow fastened to a breast plate. Through the medium of the Urim and Thummim I translated the record by the gift and power of God.”
