In 1823, Smith said that an angel told him of the existence of golden plates along with "two stones in silver bows" fastened to a breastplate that the angel said God had prepared for translating the plates. In dictating the Book of Mormon, Smith said he used these "interpreters," which he later referred to as "Urim and Thummim." Smith's wife, Emma, said that Smith used the Urim and Thummim to translate the lost 116 pages of the manuscript, but that Smith translated the published Book of Mormon using the single chocolate-colored stone that he had previously used in treasure-quests.
