Nonmetallic Breastplates in Native North America

        A less common but significant criticism of the Book of Mormon concerns the apparent lack of metallurgy during its historical period. This lack would make metallic arms and armor, especially breastplates anachronistic. (See #23 here.)

        Setting aside broader explanations for anachronistic metallurgy and weaponry, the criticism of breastplates is particularly odd given the numerous historical examples of nonmetallic armor. In some regions, such breastplates continued to protect individuals against gunpowder weapons well into the 1800s. Thus, when critics insist that a breastplate must mean metal armor, they are imposing their preconceived image of medieval knights in shining armor onto the text. Outside of the artifacts discovered by Limhi’s scouts (Mosiah 8:8), which appear exceptional enough in their own right to warrant special attention, the term breastplate could easily refer to a variety of nonmetallic armor.

        Everything listed below has an upstream source but to prevent incredibly long footnotes I’m only citing Native North American Armor, Shields, and Fortifications by David Jones. (Though I  made several exceptions to name a primary source.) I also do not include various types of armor such as rod or slate armor that also have rigid torso protection and I limited myself to descriptions that included the term breast plate.[1]  

Examples of Nonmetallic Breastplates and Armor

California

- “The corselet had two layers. Within the inner layer the rods were sewn in tight horizontal layers, looking exactly like the hairbone breastplates of the Plains Indians.” (20)

Plains and Southwest

- “The Apaches…began making protective armor of tough, overlapping leather for both themselves and their horses, imitative of Spanish mail.” (40)

- At a 1731 battle, Apache warriors were wearing “leather breastplates,” also described as “leather jackets.” (85)

Northeast

- “Their breastplates were also a fabric of wood or little reed wands, cut in proportional lengths, clasped against each other, twined and woven very neatly with little cords made of antelope or deerskin…their breastplates were made to resist arrows with bone or stone heads but would have been no protection against iron arrowheads.” (58-59)

- “Some [Iroquois had] a sort of cuirass or breastplate of small pliable rings, very neatly worked.” (Pierre Charlevoix, 649, quoted in Jones, 60; repeated in Jones, 92–93)

- The same observer reported that the Mohawks “wear sea horse skins and barks of trees made by their art as impenetrable as steel, wearing a headpiece of the same.”  (60)

Pueblo

- Breastplates made of ribbons have been found at some Pueblo archaeological sites. (85)

Subarctic

- “In the latter 1770s, an account of the Cree stated that they wore ‘coats of mail, made of many folds of dressed leather, which are impenetrable to the force of arrows.’” (93)

- “The Chandalar Kutchin warriors’ breastplate, called eakin, was fashioned from the shovel antler of a caribou, and the Micmac hung an oblong piece of hard wood, suspended by a thong around the neck, under their rawhide war jackets as a breastplate.” (93)

- Inuit armor was “made of three rows of walrus [overlapping] ivory plates [lashed with rawhide].” (153–154)

- “The Kagamil caves…produced a thick whalebone breastplate.” (154–155)

Pacific Northwest

- Captain Cook described Tlingit armor: “They make a breast plate of wood, and an arrow proof coat of thin flexible strips bound with strings like a woman’s stays.” (Cook, quoted in Hough, 1895, 637; cited in Jones, 108)

- Tomas de Suria described Tlingit warriors as wearing “all their arms, a breast plate [of wood]…the breast and back armor are of a kind of coat of mail of board two fingers thick.” (108)

- Tlingit armor was so effective that, after the introduction of firearms, they simply added another layer of leather over the armor so that musket balls would not penetrate. (108, 111)

- “We bought some of [their armor] which look like the breast doublets in Spain but are very thick.” (114)

Southeast

- Swanton documented wooden breastplates and wicker armor among the Algonquins of Carolina, while the Cherokee used buffalo-hide breastplates. (137)

- “The circular breastplate (a plate 8–10 inches across) can also be viewed as armor…the gorgets, [throat armor], were made of wood, shell, and slate…the gorget as breastplate relative to a full cuirass is typical when a piece of armor has over time become stylized and symbolic.” (137–138)

- “When the French soldiers prepared to attack the Chickasaw fort at Ackia they donned wooden breastplates as protection against the Chickasaw arrows they expected to face.” 139)

So what?

        After surveying North American tribes nonmetallic breastplates included rods, leather, bark, wood, antlers, shells, ivory, and various animal bones. This is similar to William Hamblin's note that Mesoamerican people also used wood, bone, shell, jade, and other stones for breastplates. As with gorgets, some of these objects may have been ceremonial, though ceremonial and functional uses were not necessarily mutually exclusive.

        These European observations post-date the Book of Mormon era. However, the standard critique that metal armor was unlikely in this time frame would only make nonmetallic armor more likely and the functional standard long before European contact.[2]

        Given the use of nonmetallic protective armor in Indigenous American warfare, the absence of archaeological evidence for metal breastplates does not present a strong objection to the text. Further investigation of nonmetallic armor may yield additional insights, just as the thick Aztec cotton armor offers a potential parallel to the thick cloth armor of Captain Moroni’s army (Alma 43:19). More importantly, these examples demonstrate that assessments of Book of Mormon material culture must account for the full range of historically documented technologies rather than assume that references to armor necessarily imply European-style metal equipment.

[1] Although rod or slat armor is functionally similar, treating these forms of armor as reasonably interchangeable with breastplates would invite accusations of mental gymnastics, despite the soundness of the reasoning.

[2] One exception is the southeastern tribes, which abandoned their breastplates shortly before European contact, apparently in response to the increasing use of armor-piercing bone arrowheads, as Jones argues. This pattern of abandoning armor in response to strong, penetrating weapons has a later parallel in Indigenous responses to European gunpowder weapons, which rendered traditional armor less effective. The notable exception was the Pacific Northwest, where Indigenous peoples continued to use impressive wooden armor, even adapting it to withstand firearms.
