Abstract

Joseph Smith claimed that when he discovered the plates of the Book of Mormon, he found with them a breastplate, which he used as part of the translation process. Various historical accounts help support these claims.

Joseph Smith claimed that when he discovered the plates of the Book of Mormon, he found with them a “breastplate” (JSH 1:52). This item is never directly mentioned in the text itself, but it could very well be included in the term “interpreters”—two sacred stones which facilitated visionary sight.1 Whatever the breastplate’s precise origins, the fact that Joseph Smith claimed to discover it along with these seer stones suggests that they anciently belonged together as a set of associated Nephite artifacts.2 Importantly, other witnesses also claimed to have viewed the breastplate, and various reports can be found which help shed light on its function and physical appearance.3

Early Critical Sources

Some of the earliest references to the breastplate actually come from anti-Mormon publications. In 1830, the Palmyra Reflector mockingly referenced how “Jo. Smith … obtained the ‘Gold Bible,’ spectacles, and breastplate”4 and how the angel declared to him “I will give thee a breastplate.”5 Several years later, in his infamous book Mormonism Unvailed, Eber D. Howe gave a similar hearsay account: “They [Joseph Smith and Martin Harris] informed him [Joshua M’Kune] that ‘Smith had found a sword, breastplate, and a pair of spectacles, at the time he found the gold plates’.”6

These statements were clearly aimed at ridiculing a narrative that must have been promoted at that time by Joseph Smith or his closest followers. Thus, although antagonistic, they help establish that the story of the breastplate wasn’t simply made up after the fact.     

The Three Witnesses

The first known reference to the breastplate from positive sources (and perhaps the first known reference altogether) comes from a revelation given to Joseph Smith before the Book of Mormon was even published. In June of 1829, the Lord gave the following promise to Oliver Cowdery, Martin Harris, and David Whitmer: “Behold, I say unto you, that you must rely upon my word, which if you do with full purpose of heart, you shall have a view of the plates, and also of the breastplate, the sword of Laban, the Urim and Thummim, which were given to the brother of Jared upon the mount” (D&C 17:1).

On several occasions, David Whitmer and Martin Harris reportedly verified that the breastplate was indeed among the Nephite artifacts that they beheld when they saw the plates. William Pilkington had multiple interviews with Harris during their time together in the final years of Harris’s life, and in Pilkington’s various reports of these intimate discussions the breastplate is consistently mentioned.7 On one occasion he recorded:

I testify to the World, that I held up [Martin Harris’s] right arm while he bore his dying Testimony that he with the Prophet Joseph Smith did stand in the presence of an angel of God, while he held the Gold Plates in his hands, and turned the leaves over one by one and that he saw the Engravings on the Plates, he also saw the Urim and Thummin, the breastplate and the Sword of Laban.8

Likewise, when interviewed by Wilhelm Poulson in 1878, David Whitmer stated, “The Book of Mormon is true, as true as any record can be. I saw the angel, and I saw the sword of Laban, and the breastplate, and the Urim and Thummin, and the plates, and the director, and the angel stood before us, and he turned the leaves one by one.”9

Although we have no record of Oliver Cowdery giving a similarly direct statement about his own witness of the breastplate, he clearly believed that Joseph Smith possessed this ancient object. In 1835, Cowdery affirmingly reported specific details about the breastplate’s discovery and function (which he most likely learned directly from Joseph Smith himself).10

Lucy Mack Smith and Hyrum Smith

In addition to the Three Witnesses, there is reason to believe that others also directly witnessed or encountered the breastplate. In Joseph Smith’s own history, he stated that the angel Moroni told him to “not show [the plates of the Book of Mormon] to any person; neither the breastplate with the Urim and Thummim; only to those to whom I should be commanded to show them” (JSH 1:42; emphasis added). This leaves open the possibility that Joseph may have selectively showed some of these items to others if the Lord permitted him to do so.11

One interesting account comes from a letter written by Sally Parker, dated to August 1838. Sally was at a meeting in which she reported Hyrum Smith as making the following claims: 

He said he had seen the plates with his eyes and handled them with his hands and he saw a breastplate and he told how it was made. It was fixed for the breast of a man with a holer [hollow or concave] stomach and two pieces upon each side with a hole through them to put in a string to tie it on but that was not so good gold as the plates for that was pure.12

It is unknown precisely when Hyrum may have obtained such intimate knowledge, but it could have been soon after Joseph’s procurement of the plates. Similar reports come from Lucy Mack Smith (Joseph Smith’s mother), who gave her own accounts of how Joseph obtained the breastplate and his physical efforts to keep it safe from his enemies.13

In 1842, Henry Caswall reported Lucy as saying, “I have likewise carried in my hands the sacred breastplate. It is composed of pure gold, and is made to fit the breast very exactly.”14 Another description is given in Lucy’s famous Biographical Sketches. She reported that soon after Joseph obtained the plates, he urgently pestered Lucy to come down from her work (in the upper room of the house) and see something. She said that when she finally gave in, “he handed me the breastplate spoken of in his history.” Her description that follows gets quite specific:

It was wrapped in a thin muslin handkerchief, so thin that I could see the glistening metal, and ascertain its proportions without any difficulty.

It was concave on one side, and convex on the other, and extended from the neck downwards, as far as the center of the stomach of a man of extraordinary size. It had four straps of the same material, for the purpose of fastening it to the breast, two of which ran back to go over the shoulders, and the other two were designed to fasten to the hips. They were just the width of two of my fingers, (for I measured them,) and they had holes in the end of them, to be convenient in fastening.

The whole plate was worth at least five hundred dollars: after I had examined it, Joseph placed it in the chest with the Urim and Thummim.15

Comparing the reported statements from Hyrum and Lucy reveals a notable degree of consistency, which may be seen, at least to some extent, as mutual validation:16

Lucy Mack Smith

Hyrum Smith

“… and he shewed him the golden breastplate of the high priesthood. … I have likewise carried in my hands the sacred breastplate. It is composed of pure gold, and is made to fit the breast very exactly.”17

“It was wrapped in a thin muslin handkerchief, so thin that I could see the glistening metal, and ascertain its proportions without any difficulty.

It was concave on one side, and convex on the other, and extended from the neck downwards, as far as the center of the stomach of a man of extraordinary size. It had four straps of the same material, for the purpose of fastening it to the breast, two of which ran back to go over the shoulders, and the other two were designed to fasten to the hips. They were just the width of two of my fingers, (for I measured them,) and they had holes in the end of them, to be convenient in fastening.”18

“He said he had seen the plates with his eyes and handled them with his hands and he saw a breastplate and he told how it was made. It was fixed for the breast of a man with a holer [hollow or concave] stomach and two pieces upon each side with a hole through them to put in a string to tie it on but that was not so good gold as the plates for that was pure.”19

“Joseph, Hyrum, Cowdery & Whitmer went to the Hill Cumorah. As they were walking up the hill, a door opened and they walked into a room about 16ft square. In that room was an angel and a trunk. On that trunk lay a book of Mormon & gold plates, Laban’s sword, Aaron’s breastplate.”20

 Additional Reports

Joseph Smith’s sister, Katharine Smith Salisbury, remembered that Joseph told his family about the breastplate before he even retrieved it: “I well remember the trials my brother had, before he obtained the records. After he had the vision, he went frequently to the hill, and upon returning would tell us, ‘I have seen the records, also the brass plates and the sword of Laban with the breastplate and interpreters’.”21 Aside from the accounts of the breastplate’s discovery given by Joseph Smith and Oliver Cowdery, additional (second- or third-hand) reports relaying similar details come from Orson Pratt22 and Truman Coe.23

Joseph’s brother, William Smith, gave another detailed account of the breastplate’s physical appearance:

He also said the Urim and Thummim was attached to the breastplate by a rod which was fastened at the outer shoulder edge of the breastplate and to the end of the silver bow. This rod was just the right length so that when the Urim and Thummim was removed from before the eyes it would reach to a [pocket?] on the left side of the breastplate where the instrument was kept when not in use by the seer. I was not informed whether it was detachable from the breastplate or not. From the fact that Joseph often had it with him and sometimes when at work, I am of the opinion that it could be detached.24

This statement agrees with Joseph’s much earlier claim in 1838 that “there were two stones in silver bows—and these stones, fastened to a breastplate, constituted what is called the Urim and Thummim” (JSH 1:35; emphasis added).25

Conclusion

When viewed collectively, several lines of evidence help support Joseph Smith’s claim that, in addition to the plates of the Book of Mormon, an angel delivered into his possession an ancient breastplate:

  • Anti-Mormon publications from the early 1830s ridiculed the story of the breastplate, strongly implying that it was accepted as real and authentic by Joseph Smith and his early followers.
  • In 1829, Joseph Smith received a revelation in which the Three Witnesses were promised a view of several ancient Nephite artifacts, including a breastplate (D&C 17:1).
  • Both Martin Harris and David Whitmer reportedly stated that they had seen the breastplate, in connection with their witness of the plates of the Book of Mormon.
  • In a first-hand document dated to 1835, Oliver Cowdery related the story of how Joseph Smith obtained the breastplate, thus affirming Cowdery’s belief in the relic.
  • None of the Three Witnesses ever denied seeing the breastplate that they were promised to behold in D&C 17:1
  • Reports exist from two of Joseph Smith’s family members—Lucy Mack Smith and Hyrum Smith—claiming that they personally witnessed the breastplate. Their reports are fairly detailed and agree in several particulars.
  • Two other members of the Smith family—William Smith and Katharine Smith Salisbury—provided additional information on the breastplate. They also add to the number of witnesses who (1) knew Joseph Smith well, (2) were there when Joseph first brought the breastplate home, and (3) apparently believed in its existence.
  • Several other second-hand or third-hand reports of the breastplate were given by individuals like Truman Coe and Orson Pratt.

There are still questions that remain about this ancient Nephite artifact, its origins, its precise physical appearance, and its role during the early stages of the translation. Yet it is clear that those close to Joseph Smith during the translation of the Book of Mormon believed he possessed this item, either because they believed in his word, saw his efforts to protect it from mobs, or witnessed it for themselves.26

Although Lucy Mack Smith’s accounts of the breastplate come from late reminiscences, it seems safe to say that she was impressed by this item (as she apparently valued its worth at no less than 500 dollars). Whether it was made of pure gold as Lucy stated, or from a gold alloy as Hyrum’s statements seem to imply, or from some other metal, it would not likely have been an easy artifact for Joseph Smith to forge himself. The cost of the metal alone would have been significant, not to mention the skill needed to shape its contours to fit a human body.

At the very least, it adds one more seemingly ancient metallic relic that Joseph Smith would have been required to manufacture if he were indeed the conman that many of his critics assume. How he was able to produce a large stack of engraved gold-alloy plates, a gold-hilted sword, a brass (or bronze) ball with pointers, and a metallic (possibly gold or gold-alloy) breastplate has never been fully explained by those skeptical of his prophetic calling.27 Accounts of the breastplate’s existence therefore lend support to Joseph Smith’s claims about his miraculous discovery and translation of the Book of Mormon.
