Anachronisms in the Book of Mormon
The claim:
"Anachronisms: Horses, cattle, oxen, sheep, swine, goats, elephants, wheels, chariots, wheat, silk, steel, and iron did not exist in pre-Columbian America during Book of Mormon times. Why are these things mentioned in the Book of Mormon as being made available in the Americas between 2200 BC - 421 AD?"[1]
"Unofficial apologists claim victories in some of these items but closer inspection reveals significant problems. It has been documented that apologists have manipulated wording so that steel is not steel, sheep become never-domesticated bighorn sheep, horses become tapirs, etc."[2]
An anachronism is something showing up where it does not belong in time, like a wristwatch in a movie about ancient Rome. The CES Letter lists a dozen of them, things it says did not exist in the Americas when the Book of Mormon was written, and asks why the book mentions them. If the book describes horses and steel and wheat in a place and time that had none of those things, the argument goes, then it was made up by someone who did not know better.
It is a fair question. Some of these items really are hard, and we will not pretend otherwise. Mainstream archaeology does not accept the Book of Mormon as history, and a few of the things on this list have no clean answer yet. But the list as a whole tells a story the CES Letter never mentions, which is that item after item has moved off it, confirmed by ordinary, non-Latter-day-Saint science, over the years since 1830. The list is not growing. It is shrinking.
Start with the sword the list forgets to mention
Take steel first, because the CES Letter leads with it and because it is the clearest case.
For a long time, the standard objection was simple. The Book of Mormon says Nephi took a sword from a man named Laban, near Jerusalem around 600 BC, and that the blade was made "of the most precious steel" (1 Nephi 4:9). Critics said this was impossible. Steel, real hardened steel, did not exist that early.
Then they dug one up. At a site called Vered Jericho, about twelve miles east of Jerusalem, archaeologists pulled a complete iron sword, roughly a meter long, out of a building dated to right around Laban's time. A metals expert analyzed it and found that the iron had been deliberately hardened into steel, on purpose, by ancient smiths who knew what they were doing. The Israel Museum, where it sits today, calls it the only complete sword of its size and kind from that period yet found in Israel.[3] [4]

That is a steel sword, at Laban's time, in Laban's region, the exact thing the Book of Mormon describes and the exact thing critics said was a giveaway that the book was fake. It is not even a lucky one-off. Hardened-steel blades and tools turn up across the ancient Near East for centuries before Laban, from Armenia to Galilee to a Philistine tomb.[5] A generation ago, "there was no steel back then" was a respectable objection. The dirt answered it.
When old people meet a new animal
The animals on the list, horses most of all, work differently, and they turn on a habit of language that is easy to miss.
When a people runs into an animal they have never seen, they almost never invent a brand-new word for it. They reach for a word they already have. When the Spanish brought horses to the Americas, the Aztecs did not coin a new term. They called the horse mazatl, their word for "deer," because that was the closest large animal they knew. The Maya called the same horses tzimin, then used a version of that word for the tapir too. Going the other way, Spanish explorers met the American bison and called it vaca, "cow." One Native American group looked at imported European sheep and called them "looks-like-a-cow."[6] [7]
Scholars call this loan-shifting: when people attach a familiar name to an unfamiliar thing. Nobody invented it to rescue the Book of Mormon. It is a documented, ordinary pattern that happens every time cultures collide. So when the Book of Mormon says "horses," it does not automatically mean the modern animal. It may mean whatever creature the Nephites decided to file under the word they already had, the same way the Aztecs filed horses under "deer."
The text itself drops hints that fit this. Across the whole 531-page book, horses come up only fourteen times. Nobody ever rides one. There is no cavalry, no mounted warfare anywhere, which is a strange thing to leave out if you are a frontier American in 1830 imagining an ancient war epic, since horses and battle went together in every story he knew. At one point horses are simply grouped with cattle as food to store up during a siege (3 Nephi 3:22). That restraint is not what forgery looks like. A made-up ancient civilization tends to gallop.
None of this makes horses an easy item, and the in-depth version lays out both the promising evidence for late-surviving American horses and the real problems with it. But the question is not as simple as "horses did not exist, so the book is false." It runs straight into how human language actually behaves.
The item they left off the list on purpose
Here is the one that turns the whole approach around. Barley.
The Book of Mormon mentions barley as a Nephite crop and even as a unit of value, something you could trade with (Mosiah 9:9; Alma 11:7). For decades critics counted barley among the impossibilities: no barley in the ancient Americas. Then in 1983, archaeologists working a pre-Columbian site near Phoenix found cultivated little barley, a real native American grain, grown long before Columbus. Once they knew to look, they found it again and again, in Illinois, Iowa, Kentucky, Oklahoma, Colorado.[8] [9] One of the scholars who confirmed it, not a Latter-day Saint defending anything, called it "a North American domesticated grain crop whose existence has not [previously] been suspected."[10]

Now notice what the CES Letter does. Its list names wheat and silk and iron, but it leaves barley out entirely. Barley used to be a star witness for the critics, and once the science went the other way, it simply disappeared from the indictment. That is worth sitting with. The list you are being shown is not a fixed set of facts. It is curated, and the item that got confirmed got dropped.
To be fair, this native barley is a different species from the Old World barley Lehi's family knew in Jerusalem, so it is not a perfect bullseye. But it does sink the claim that barley could not have grown in ancient America at all, which is the claim that was actually being made.
The whole list keeps moving one direction
Step back from any single item, because the pattern across all of them is the real point.
A scholar named Matthew Roper went through every item anyone has ever called a Book of Mormon anachronism, from 1830 down to today, and tracked what happened to each one over time. The trend is steep and it runs one way. In the mid-1800s, around 90 percent of the flagged items were unconfirmed, open question marks. By 2024, after almost two centuries of archaeology and linguistics, only about 9 percent were still unconfirmed.[11] A separate study by John Clark, looking at lists from nineteenth-century critics, found the same thing and put it plainly: "The overall trend in the data over the past 175 years fits the expectations for the Book of Mormon as history rather than hoax."[12]
Both of those counts deserve a grain of salt, since both come from Latter-day Saint scholars who decided what counts as confirmed, and the in-depth version is candid about that. But the basic direction does not depend on the exact percentages. Item after item, the movement has been from "that could not have existed" to "actually, here it is": barley, hardened steel at 600 BC, cement in ancient Mexico at the date the book gives, curved swords, fortifications, pre-exilic Hebrew worship halls, Hebrew names later found on ancient documents. Things keep coming off the list. Almost nothing goes back on. If the Book of Mormon were a clumsy nineteenth-century invention, you would expect the opposite, more problems surfacing as we learned more. The reverse has happened.
There are many more items than the four I have walked through here: silk, chariots, "coins" (a word that, it turns out, never actually appears in the Book of Mormon), elephants, synagogues, and others. Each has its own story, and the full list is in the in-depth version, sorted by how strong the evidence is.
The ones still without answers
Here are the items that do not have clean answers.
Wheat. No one has found wheat in pre-Columbian America. You can argue, reasonably, that "wheat" in translation might stand for some native grain, the way "barley" did. But that argument cannot be checked, and right now there is no physical evidence. Wheat is the weakest item on the plant list.
Iron and steel made in the New World. The Old World steel is solid, as we saw. But the Book of Mormon also describes Nephites and Jaredites working iron and making steel swords in the Americas, and there the evidence is simply missing. No ancient iron furnaces, no slag heaps, no forged iron tools or weapons have turned up anywhere in the pre-Columbian Americas. Some defenders have pointed to Olmec craftsmen who ground and polished iron ore into beads, but polishing ore is not the same as smelting metal out of it, and treating it as an answer blurs a line that matters. On New World ironworking, the critics are right: the evidence is not there.
The things the book leaves out. This is the sharpest one, and it cuts the opposite direction from everything above. If the Nephites really lived in ancient Mesoamerica, you would expect their record to mention the things that defined that world: cacao, the dominant trade good and ritual drink; the jaguar, the central animal of Maya religion; the ritual ball game played across the region for thousands of years; and above all obsidian, the volcanic glass that was the cutting edge of nearly every Mesoamerican weapon. The Book of Mormon spends roughly sixty chapters on warfare, cataloging swords and spears and shields in detail, and never once names obsidian. We know these things were central to Mesoamerican life, so their absence is not a gap waiting for some future shovel to fill. It is just absent. Of every form the objection takes, this is the one with no finished answer.[13]
And underneath the specific items sits the broadest challenge, the one made not by the CES Letter but by the Yale archaeologist Michael Coe: that even if every single item were resolved, the overall cultural picture the Book of Mormon paints, a literate, iron-using, horse-and-cattle civilization, still does not match what archaeologists have actually dug up in ancient Mesoamerica.[14] [15] That mismatch is real, and the in-depth version takes it on directly rather than waving it off.
Why anachronisms can't decide it
So where does that leave a worried reader? With a ledger that has real entries in both columns, and that is the truth of it.
The anachronism debate cannot prove the Book of Mormon false. Too many of its supposed knockout items have quietly become evidence for the book instead, and the list has only shrunk with time. But it cannot prove the book true either, because the cultural picture does not fully line up and a handful of items still have no clean answer. By itself, this debate settles nothing. It only narrows the field.
Which is why it helps to remember what does not hang on any single artifact. A young man with almost no schooling dictated the Book of Mormon out loud, start to finish, in roughly sixty working days, with no notes and no rewriting of earlier parts as he went, in front of scribes who watched it happen and never took back what they saw. The book holds its own internal geography across hundreds of pages, carries Hebrew patterns of writing, and names real places on the Arabian Peninsula that archaeology only confirmed long after Joseph Smith was dead. No one has given a workable account of how it exists if it is not what it claims to be.
That is the firmer ground. And on the narrower question of anachronisms, notice the direction of travel. The very item the CES Letter leads with, steel, is sitting in a museum case in Jerusalem, a complete blade from Laban's time and place, answering a verse critics once said could not be true. Not everything on the list resolves that cleanly, and some of it may never resolve at all. But across nearly two hundred years, item after item, the evidence has moved toward the book, not away from it.

Three partial responses are commonly offered. (1) The abridgment defense. Mormon was selecting religious and military material rather than producing a cultural ethnography, which could explain why peripheral items (cacao as a commodity, jaguar imagery in everyday life) might be omitted. The limit: this fails for obsidian, whose military significance an abridger working through sixty chapters of warfare narrative could not avoid, and for cacao, whose economic and ritual significance was pervasive enough that any chronicler would encounter it. (2) The translation framework. Unfamiliar terms might have been rendered generically -- obsidian as "stone" or "flint," for example. The limit: this is unfalsifiable as a general move, and the Book of Mormon's weapons are not described in stone-tool terms either; they are described in metallic terms (swords, cimeters, breastplates). (3) Cultural distinctiveness. Nephite culture may have been substantially different from surrounding Mesoamerican cultures. The limit: this creates tension with the Mesoamerican model itself, which relies on overlap with Mesoamerican archaeology to argue for a Mesoamerican setting in the first place. Each response carries partial weight; none individually resolves the obsidian and cacao absences. ↩︎
