Book of Mormon Plates
When the angel Moroni first appeared to Joseph Smith on the night of 21 September 1823, “He said there was a book deposited, written upon gold plates” (Joseph Smith History 1:34). Others were later privileged to see the plates and some even hefted them and leafed through the plates themselves. The three witnesses declared that they had “seen the plates which contain this record” and “the engravings which are upon the plates,” but their official statement, published at the beginning of the Book of Mormon since 1830 gives no further details about the plates. On the other hand, in their published statement, the eight witnesses declared that Joseph had shown them the plates, “which have the appearance of gold; and as many of the leaves as the said Smith has translated we did handle with our hands; and we also saw the engravings thereon, all of which has the appearance of ancient work, and of curious workmanship.”
In subsequent interviews, some of the witnesses (including others who saw the plates) described the ancient book in more detail, estimating its size and weight. A number of articles discussing such descriptions have been published, including the following, which are available on the web:
