>Several individuals have suggested that the dodecahedra are knitting aids, specifically for knitting gloves, with different sized holes intended for the different sizes of fingers, and the pegs serving as a lattice to hold the yarn.
This is mentioned in the article but treated as a joke:
> Other internet researchers, perhaps less seriously, have used 3D-printed models of the Roman dodecahedrons for knitting experiments, and suggested that the true purpose of the objects was to create differently sized fingers for Roman woolen gloves.
Although IIRC when it was first proposed the people who proposed it seemed very earnest and to see it as obvious.
And it nicely explains a lot of the peculiarities e.g. the nubs make sense for attaching yarn, and different people have different finger sizes (up to layers) but the precise sizing is not super important as long as you have a gradation with steps which aren't too big.
It also looks quite close to spool (or "french") knitting.
Though there's the objection that the dodecahedra are serious overkill for those needs when a plank with a few nails would do the trick. There's also the "OOPArt" factor: knitting spools were invented in the 17th century or so, and known records for circular knitting are not that much older.
It does also explain why they are not found all over the Roman empire but mostly in the north (the article mentions England, Germany, and the Netherlands) where it is probably COLD for the average Roman legionnaire
If this was the explanation, there would be wear patterns on the waist of the nubs, and inside the rings just near the nubs.
Many of the potential suggestions can be discarded because they would cause very specific wear patterns that would be repeated across many dodecahedrons.
This seems plausible. I wonder if they could identity any particulate from the fibers around the knobs that might corroborate this.
On the wikipedia page there is an icosahedron pictured next to these that does not have finger size holes but I suppose that could be unrelated to this artifact's purpose.
Similar, but made with wood and nails, which makes way more sense for a knitting aid. Much cheaper and easier to produce.
Also, the dodecahedrons are found in sizes ranging from "4 to 11 cm" in size (according to Wikipedia). That _might_ make sense if there were specialized ones for everything from kids to very large adults, but then...why aren't they found in clusters? You'd expect some towns in the Roman Empire, where gloves were made, to be full of them (in sets, not individual pieces). Instead, they turn up individually and fairly randomly throughout much of the Empire. They often turn up in coin hoards, too, which is an odd place to store a glove-making doodad.
Compare to needle cases, which were similar womens' tools. Most of them were wooden or bone, but rich women would get fancy ones made of bronze, and pretty commonly be buried with them.
Clothing production in historical contexts (including Roman) is usually a household activity. This mostly means it's done by women of all classes, if only perhaps as a show of virtue. A glove-making device, as a personal item, might show up randomly any place they were used.
Conspicuously expensive household items would also not be unknown. It makes some sense that the bronze survivors may be those owned by wealthy women, where the bulk of those used may be (unlikely to survive) wood.
The knitting thing just doesn't add up at all even if it's kind of clever. Why would you make it from bronze? Why don't you find orders of magnitude more of these made from wood? Why would someone want to be buried with a knitting jig?
Sewing, spinning, weaving, and knitting tools are fairly common grave goods to find in women's graves: spindle whorls, needle cases, bone beaters, etc. As far as wood vs. bronze, almost certainly survivorship bias. The only wooden objects that survive that long are those that have fallen in bogs, where the anoxic environment prevents rot. Normal wooden grave goods will have rotted away by now.
"They have been found across a northwestern swath of the former Roman Empire from Hungary to northern England, but not in other Roman territories such as Italy, Spain, North Africa, or the Middle East."
as these are lifestock producing cold regions (and back then were more colder and swampy than today) where probably knitted wool was used instead of the textile that was used in the warmer regions where agriculture produced source fiber for the textile.
I wonder how many cheap plastic Happy Meal toys will someday thousands of years from now be dug up and deemed to have special religious significance to our culture.
if history is any guide then the future archeologists looking at the content of our internet will conclude that we're living in matriarchate these days (with Pamela Anderson interpreted along the lines of "religious figures,[5] an expression of health and fertility, grandmother goddesses") like the today's scientists conclude that about past societies upon finding this Venus figurines
Or like for example another interpretation there produced by scientists who seem to have never seen that Kim Kardashian Instagram post :)
"It has been suggested that they may be a sign of an earlier prevalence of steatopygia, now associated principally to women of certain African or Andamanese ancestry. However the Venuses do not qualify as steatopygian, since they exhibit an angle of approximately 120 degrees between the back and the buttocks, while steatopygia is diagnosed by modern medical standards at an angle of about 90 degrees only.[21]"

The use of “No” here suggests a dearth of experience with Happy Meal toys, because these aren't opposed ideas.
People disagree with the rangefinder theory because "no two Roman dodecahedrons are the same size". But the only thing that matters for a rangefinder is the ratio between the sizes of opposing holes (edit: and face-to-face distance). Anything we know about that?
Given the intricacy of the smithing that seems less than sensible, it's not like the size of the items changes significantly, so having markings you can just wipe away and needing to re-measure and re-mark the item regularly sounds far from optimal.
> having markings you can just wipe away and needing to re-measure and re-mark the item regularly sounds far from optimal.
Unless the delibility of ink was a feature they desired. Hypothesizing that they were trying to prevent a working ranger from falling into the wrong hands wouldn't strike me as absurd. Dropping them in a firepit or stream to remove the ink would be pretty handy if you know your military encampment is about to be over-run and you can't save everything.
I'm just wondering if this tool is for taking the measure of finger size to make rings? but then it seem kinda odd to be inside of wealthy woman grave.
What if it was the finger measurements of all 10 fingers of a specific person? As in they have so much jewelry made they can’t be bothered to constantly go to the jeweler, so they send their dodecahedron instead?
Of course that leaves the question of the two extra holes. But it would certainly be a status symbol.
For most of the uses posited in the article, it seems like icosohedra (coincidentally, the dual of the dodecahedron) would have made more sense. After all, if 12 pairs of opposite faces are good, wouldn't 20 be better?
I think they could just be pretty, ornate keepsakes, or maybe a sort of teaching tool in the direction of geometry. My qualifications: none at all, but I enjoy pretty, ornate things, and I would keep one of these on my desk. They're also clearly interesting geometrically.
I’m sure this is not an original theory, but when I saw the device i immediately thought that it may be a tool to sort / check the size of coins. Each size lines up to a known gold or silver piece. The largest hole allows all to be removed easily.
Not sure if it adds or detracts from your theory, but coins were sometimes clipped to change their value. I’ve got a silver one that had the edge clipped off to alter its value.
One of my engineering friends devoted a large portion of his life studying the dodecahedron. He believed it was used as a "fluid scanner" to measure the displacement of 3d objects using water.
Oh man, that brings back memories. Roman System Engineering a.k.a. "TimeCube with Tits"! They still have the original promo 'marketing' on Vimeo: https://vimeo.com/29490154
I believe these dodecahedrons come in a whole variety of sizes, and aren't particularly consistent (i.e. there's not 3 standard sizes, just a whole range). That undermines a lot of potential explanations.
I was going to say, a flat object (out of wood or metal for 'genuine-ness') would be a lot more practical, and they'd be using them everywhere.
In western Europe, they would use scales to determine the weight of coin, since size itself doesn't mean much - that's logic used by modern day vending machines.
Of all the theories, this seems plausible. Has anyone done that to your knowledge? The easy way to test this is to take an assortment of Roman-era coins and see how well they match up to the holes and ring sizes. The pegs that protrude could easily help not only to stabilize the system but prevent coins from sliding off if placed in a stack.
they did mention they appear to be of widely varying sizes... I imagine if the holes were meant for specific coins they'd all have matching sizes...
I like the idea that the ratio between the incoming and outgoing holes allow you to get correct angles while looking through regardless of how the object is held (look through one of the smaller holes hold it far enough that the larger hole matches, and you have an exact angle viewer)
If it was a tool for commerce you would expect them to appear all over the old Roman empire and especially in Italy but according to the article they are only ever found in the northwestern parts of Europe. Also, if the purpose was validating currency the holes would need some markings indicating which hole matches what coin, wouldn't they?
Most of my tools around the house have minimal markings, if any. There are a zillion sizes of Allen key, and very few have the decency to mark themselves.
My measuring cups have markings are marked in paint, most of which has already worn away. Wouldn't stand a chance over millenia.
That said, you'd expect at least one or two to have informative notches for sizing. The universal dearth of text for such a common device is surprising.
And also, wouldn't they be a standard size for the region if they were for measuring coin? It sounds like each dodecahedron was different sizes.
I don't usually bother to complain about ads, but this site is really atrocious. It auto-played me 6 ads (including the same one several times) before playing the video (that I'm not interested in anyway). Then it keeps following me around as I scroll through the ad infested article. Someone somewhere should be shot.
It also managed to add dozens of entries to my history (probably as I was scrolling), making it impossible to go back to the HN thread. That website should be on the Chrome malware list.
Gavin Smith (Robots and Dinosaurs) has a theory that they are calendars. He has an interesting series of articles in which he tries to recreate their use.
I really like this theory, especially because it accounts for the varying hole sizes, adjoined balls, and the 12 sides and 30 edges that only a dodecahedron could provide. None of the other theories account for all of these unique attributes.
The mental floss article mentions one was found on a decayed staff. The knitting theory seems like it could be fulfilled with a far simpler instrument IMHO.
If you look at modern shortcut knitting equipment like knittingboard.com it looks pretty similar. It sounds more and more like shark tank gadget of the roman empire.
A supporting tidbit that I didn't see mentioned is that these seem to appear not long after the switch to a 12 month calendar. Julius Caesar made the 12 month calendar official in 46 BC, and the earliest of these cubes appears around the 2nd century AD (though I saw a couple sources mentioning the first century).
The abundance in military sites still seems consistent. Up until then, the calendar was held in alignment with the seasons by adding months, nearly at random (for example, they were sometimes used to extend/shorten the tenure of politicians). They basically ignored 50 or 60 days a year, and made months up to cover that. If you're away at war, you don't get those messages, and your calendar no longer reflects the seasons or anything.
If I were taking a wild guess, I agree it's a calendar, and I would specifically guess it was used for pay schedules for the soldiers. Rome started paying its soldiers around the end of the 2nd century BC, and they paid monthly from what I can tell.
The evolution seems natural. Rome starts paying soldiers. Soldiers get upset that while at war, their months don't line up with Rome's months due to not getting the memo about randomly added months. Rome institutes a standard calendar for many reasons, one of which is to stop having hoards of armed people angry about not getting paid correctly. Now that the calendar is standard enough to follow while away from Rome, a device is invented to track the months so that soldiers get paid on time and it feels more transparent than the "just trust me" of old.
I think it also provides an adequate explanation for why they were made of expensive materials. The calendar was not just for tracking time, it was directly associated with the wealth of the Roman empire, their ability to pay their soldiers. It's more reassuring when they guy with the brass calendar says you'll get paid on time than when the guy with a wooden one does it.
But if they were used for pay we should have some sort of documentation. There would be mention of them in diaries, ledgers or artwork just like most every other aspect of Roman military life. There would be a story about one being lost on campaign, resulting in pay errors. There would a few on a mural depicting an accountant's or officer's daily life.
I think they are something more mundane. Pocket candle holder seems plausible. But the flip side is that with mundane items we should see greater diversity across the empire. The fact that we don't suggest a tie to something universal like religion or politics. Maybe they were a calling card, proof that the bearer was a member of a particular group or cult.
AFAIK, we don’t have a lot of “daily life” text from early Roman times. We have architecture and stone/tile art, from which we learn a lot about culture. And we have major milestones where those justified documentation. “Soldiers: how you get paid” is not likely in any of what we have. And it may not have been written; literacy was not high.
Just terrific. Not the just content. But the whole process of speculation, digging, testing theories, sharing ideas on a blog. Scholarship outside of academia. Feels old school somehow.
I immediately thought of Plato and western esotericism. These look magical. Plato's atomic theory in Timaeus was that atoms should be the simplest geometric forms possible. These are what we now call the Platonic forms: the tetrahedron, the cube, the isocahedron, the octohedron and the dodecahedron. Plato associated each with an element, based on the intrinsic material properties of the geometric shape. For instance, earth was cubic because cubes stack well and fire was tetrahedric because the sharpness of the pyramid-shape was destructive like fire.
Dodecahedra were the 5th element, the quintessence, which was the aether beyond air. Totally magical. These things would have impressed people and communicated philosophical prowess.
Anyone interested in this kind of stuff (i.e., the Western Esoteric Tradition) would enjoy The Secret History of Western Esotericism podcast. Lots of great scholars and scholarship on this understudied aspect of Western civ. https://shwep.net/
Not so weird, you want your dice to be maximally symmetric for fairness. When you add easy manufacture to the qualifications, only the platonic solids will do.
That is correct, I'm an idiot. Almost only the platonic solids will do? Honestly it seems like the platonic solids are the easiest to work with, except percentile dice are nice for people using base-10 so you have to throw in a 10-sided die too. There are non-platonic versions of the other dice too, but you don't see them I assume because they're harder to manufacture. Less cut and dry than I though though!
The original D&D dice were the 5 platonic solids, the 10s were added later.
But there are lots of shapes that can be "fair". You can stick 2 pyramids with any number of sides together, you can make a long prism with any number of sides since it will never land on the long ends, a coin can be considered to be a 2 sided die. I seem to recall somebody made a 30 sided die where the sides were parallelograms, although I never had one.
yup the original d20's were labeled 1-10 twice, and you used a crayon to colour the on set differently. If it landed on your "blue" 10 it was a 20, if it landed on the uncoloured 10 it was 10 for example.
Any regular bi-pyramid would be technically fair. I think it's just that you tend to get rounder dice by using platonic solids or tesselating / modifying platonic solids.
I know the “Zocchihedron”, one of the first and best known commercial ones, is not fair (after this was proven, they were renumbered so that the over-/under-weighted results were better distributed over the range, but it's still not fair.)
> Most players use d10 pairs with a tens die, though, because they roll better.
There's also a nifty trick used in many RPGs based on d100 to roll once and have 2 d100 numbers (by inverting the result).
So for example in Warhammer you roll d100 for attack, you hit if your result is lower than your Melee Combat attribute, and the inverted result shows which part of the enemy body you hit (that influences critical hits and armor).
All that is required for fairness is equal faces and equivalent reach behavior.
Every total symmetry fits. You don't need a platonic solid. By example, every even number six or up can be fairly represented as two pyramids joined at the base.
Many fair non-platonic dice exist besides the d10, such as the d30. Go ask at the game store
I actually own a d30, as well as a super weird looking d3. But you don't generally see non-platonic solids for anything but a d10. Why? My guess was ease of manufacture, but honestly IDK.
The pentagon and dodecahedron are also very interesting mathematically. Squares and triangles tile the plane, and have nice "round" number angles 90° and 60°. Pentagons don't tile and feature 108° angles. The diagonals of a convex regular pentagon are in the golden ratio to its sides. The inscribed pentagram has a very recursive feel for this reason, "tiling" (nesting) off to infinity.
Yes, like Max Tegmark, they believed the world was made of math. Where harmony means wholeness, they believed in harmonies in numbers (1+2+3+4=10), harmonies in numbers in space (geometry), harmonies in numbers in time (musical ratios) and harmonies in numbers in space and time (astronomy; harmonies of the spheres).
They also conducted the first hypothesis driven experiment in western science when they cast bronze chimes with corresponding ratios of thickness (1:2, 2:3) to see if the pythagorean tuning of strings was a generalizable property.
Plato extended pythagoreanism to make the world of math into the world of pure forms—a universal, immortal realm. He also continued the esoteric tradition of the pythagoreans, who had to keep their practices secret because they kept getting slaughtered.
It's just the best history. Pythagoras was also gender inclusive—not only were there many female pythagorean philosophers, he also (according to aristoxenus) openly credited his moral doctrines to Themistoclea. For integrating science and spirituality at the start of western civ, pythagoreanism is pretty much the coolest.
> Although dozens, and perhaps hundreds, of explanations have been offered to account for the dodecahedrons, no one is certain just what they were used for.
There's no shortage of ideas, and it's ok to share your ideas, but the interesting point is we just don't know which of the many ideas is correct.
If any of them. In archeology you can go pretty far assuming that any elongated object was used as a sex toy. However, this object is a dodecahedron, so we are all baffled.
I've long wondered if several millennia in the future people might find frequent fossilized remains of certain mundane objects from today and try to ascribe some deep social significance or complex technical function to them. For example, these decorative balls that seem to be in bowls on so many American dinner or side tables.
These undersea creatures were so highly prized that the ancients kept them in small caches, or “tide pods”, in their living quarters. The surviving sources recommend strongly against swallowing anything in a tide pod, so it is assumed they were poisonous unless properly prepared.
Almost any internal part of a large machine would be inscrutable. Most are inscrutable even now. If you handed an automobile carburetor to a person under 35 they would struggle to identify it, and even if you handed it to a car mechanic, 25 or younger, they would struggle to identify it, as fuel injection became standard by the 1990s and old cars with carburetors largely vanished by 2010 or 2015. And yet anyone 50 or older will remember seeing them in their cars any time they popped the hood.
A central fuse box has been standard in all new homes since at least 1945 if not 1930, so if you hand someone a disposable fuse from 1930, would they be able to guess the purpose?
My dad was a photographer from 1950 to 2007 and he kept the "dark room" in the basement of our house, a large room full of thousands of objects. He was an expert and dodging and burning, decades before Photoshop. He created his own tools for the dodging and burning, typically by taking a coat hanger and bending to the right shape, then attaching some cardboard and wrapping it with tape. It was a specialist tool and even in 1970 or so, 99.99% of the people on the planet would not have been able to guess the purpose.
With respect, I’m over 50, and the only reason I know anything at all about carburetors is that my cousin has built them for decades for use in race cars. Still does, as a side job.
But Destin on “Smarter Every Day” taught me way more about them than I ever learned from my cousin.
carburetors exist on more than just cars. Lawnmowers, ATVs, motorcycles, etc.
Given that someone is already skilled in engine maintenance, seems unlikely they wouldn’t recognize a common engine component in all classic cars and most small engines.
Furthermore, what’s with the argument that someone would be completely unfamiliar with an object/event/concept that existed before their time? I see this argument used from time to time, and it’s baffling. Are you completely unfamiliar with everything that was not longer manufactured after you were born? Does it surprise you that a ton of young people are interested in restoring classic vehicles (and electric retrofits) and there is a large online community of such?
The human species hasn't changed, the stuff they're familiar with has changed.
And I think you underestimate the younger generations, I'm under 35 and could trivially identify a carb or fuse.
Furthermore, I would be unsurprised if my 5 year old could also identify those inscrutable things, he 'helped' me get the snowblower ready for the season and winterize the power washer a month ago, and watched/helped while asking endless questions as I replaced the water heater last weekend. It sits adjacent to the furnace, which has a discrete Edison fuse; I don't recall if that was part of the litany but it probably was.
“Smaller dodecahedra with the same features (holes and knobs) and made from gold have been found in South-East Asia along the Maritime Silk Road. They have been used for decorative purposes and the earliest items appear to be from the Roman epoch.”
Rome had ports in the Red Sea, and during Trajan briefly also in the Gulf of Persia. I would think it was stranger if they didn't have exchange along that route.
Perhaps not as prolific as the trade along the landed silk road, but there's a smattering of roman coins and artifacts all over SEA.
which suggests a corslet being stiffened with "pale mountain bronze". Perhaps the "pale mountain bronze" is in the form of a dodecahedron? Then did a search for ancient images of women wearing toga's and found this:
Look at her shoulders. Maybe these dodecahedra were ornamental fasteners for clothing, with the different hole sizes allowing them to be used with different weights of fabric. So perhaps they were a fad fashion adornment for rich women (due to the cost of the precision manufacture). I could see the smaller ones being used as a weight attached to clothing to control the drape and accentuate the figure as well. Pull some cloth through it, tie a knot and it pulls on the cloth in a certain way. A hair ornament would make sense also, with the different sized holes allowing for pulling differing amounts of hair through the holes and knotting the hair to hold the ornament in place.
I can't help but think of the fidget spinner craze from a few years ago... humans (and perhaps other hominids before them...) have always made little trinkets for decoration and entertainment, with usage being individualized. Maybe some people wore them as jewelry while the kids made little dice-like games with them? Think of like a hackey-sack - one person squeezes it as a "stress toy" while another kicks it around with their friends as a game. Same basic thing, multiple uses, none of which really require documentation in history.
Two thousand years from now an article might read:
No one is certain why tribes all across planet in the midst of a pandemic and the a looming extinction became so obsessed with computer hardware that seemed to have achieved no practical function other than to perform intensive compute operations.
Some researchers suggest that these instruments had a special cultural significance, and perhaps even a religious function.
It hasn't gotten anywhere; I assume that's mostly because making assumptions tends to let you publish papers, while not making assumptions tends to stop you from publishing papers. There's no incentive in the system for accuracy.
It is thought that these tribes worshipped Satoshi Nakamoto, who they believed to be the creator of Bitcoin, and that when the final bitcoin was "mined", a new era would begin.
It is unknown if Satoshi Nakamoto was in fact a real person, as there is there are no surviving primary sources or direct evidence of his existence.
I would bet these are dice. The Romans are known to have played a variety of dice games, including in the backgammon family, a family of games known to sometimes use 12d dice (Source: Oxford History of Board Games by David Parlett)
The other day I stumbled upon an episode of 'Tougher than nails', some kind of 'Survivor'-type show for craftsmen. One of tasks to complete involved using metal templates to properly shape the diameter of a round wooden rod. Well, this required a lot of hammering...
So just as a guess, could that be used to smoothen some rods, like arrows or spires? It would be rather a manual tool, like a sanding block.
Another guess, is some kind of junction holder. Like a wheel/spokes hub or some sliding rope knot in harnesses, or tent-pitching aid.
Made of bronze there must be some reason for durability, hardness, water contact?

The evolution seems natural. Rome starts paying soldiers. Soldiers get upset that while at war, their months don't line up with Rome's months due to not getting the memo about randomly added months. Rome institutes a standard calendar for many reasons, one of which is to stop having hoards of armed people angry about not getting paid correctly. Now that the calendar is standard enough to follow while away from Rome, a device is invented to track the months so that soldiers get paid on time and it feels more transparent than the "just trust me" of old.
I think it also provides an adequate explanation for why they were made of expensive materials. The calendar was not just for tracking time, it was directly associated with the wealth of the Roman empire, their ability to pay their soldiers. It's more reassuring when they guy with the brass calendar says you'll get paid on time than when the guy with a wooden one does it.
I think they are something more mundane. Pocket candle holder seems plausible. But the flip side is that with mundane items we should see greater diversity across the empire. The fact that we don't suggest a tie to something universal like religion or politics. Maybe they were a calling card, proof that the bearer was a member of a particular group or cult.
I hope he's proven correct.
Dodecahedra were the 5th element, the quintessence, which was the aether beyond air. Totally magical. These things would have impressed people and communicated philosophical prowess.
True; IIRC, the rules used d10 but it was a way of reading the d20 before d10s were manufactured.
By the way, you can get d100 dice.
Can you get fair d100s, though?
I know the “Zocchihedron”, one of the first and best known commercial ones, is not fair (after this was proven, they were renumbered so that the over-/under-weighted results were better distributed over the range, but it's still not fair.)
Most players use d10 pairs with a tens die, though, because they roll better.
Do you have a link for the pyramid one?
There's also a nifty trick used in many RPGs based on d100 to roll once and have 2 d100 numbers (by inverting the result).
So for example in Warhammer you roll d100 for attack, you hit if your result is lower than your Melee Combat attribute, and the inverted result shows which part of the enemy body you hit (that influences critical hits and armor).
Every total symmetry fits. You don't need a platonic solid. By example, every even number six or up can be fairly represented as two pyramids joined at the base.
Many fair non-platonic dice exist besides the d10, such as the d30. Go ask at the game store
They also conducted the first hypothesis driven experiment in western science when they cast bronze chimes with corresponding ratios of thickness (1:2, 2:3) to see if the pythagorean tuning of strings was a generalizable property.
Plato extended pythagoreanism to make the world of math into the world of pure forms—a universal, immortal realm. He also continued the esoteric tradition of the pythagoreans, who had to keep their practices secret because they kept getting slaughtered.
It's just the best history. Pythagoras was also gender inclusive—not only were there many female pythagorean philosophers, he also (according to aristoxenus) openly credited his moral doctrines to Themistoclea. For integrating science and spirituality at the start of western civ, pythagoreanism is pretty much the coolest.
However very interesting group! Wish they were still around :)
This was either a sex toy where you can insert your penis or a portable sausage maker.
My comment intent was absolutely serious and a humbling attempt to study the problem without bias.
(but as others have said in the comments here, I also do not think that a casual discussion on HN is as good as the studies done so far)
There's no shortage of ideas, and it's ok to share your ideas, but the interesting point is we just don't know which of the many ideas is correct.

Or perhaps they will think they are so bizarre extinct ocean animal.
A central fuse box has been standard in all new homes since at least 1945 if not 1930, so if you hand someone a disposable fuse from 1930, would they be able to guess the purpose?
My dad was a photographer from 1950 to 2007 and he kept the "dark room" in the basement of our house, a large room full of thousands of objects. He was an expert and dodging and burning, decades before Photoshop. He created his own tools for the dodging and burning, typically by taking a coat hanger and bending to the right shape, then attaching some cardboard and wrapping it with tape. It was a specialist tool and even in 1970 or so, 99.99% of the people on the planet would not have been able to guess the purpose.
But Destin on “Smarter Every Day” taught me way more about them than I ever learned from my cousin.
Given that someone is already skilled in engine maintenance, seems unlikely they wouldn’t recognize a common engine component in all classic cars and most small engines.
Furthermore, what’s with the argument that someone would be completely unfamiliar with an object/event/concept that existed before their time? I see this argument used from time to time, and it’s baffling. Are you completely unfamiliar with everything that was not longer manufactured after you were born? Does it surprise you that a ton of young people are interested in restoring classic vehicles (and electric retrofits) and there is a large online community of such?
And I think you underestimate the younger generations, I'm under 35 and could trivially identify a carb or fuse.
Furthermore, I would be unsurprised if my 5 year old could also identify those inscrutable things, he 'helped' me get the snowblower ready for the season and winterize the power washer a month ago, and watched/helped while asking endless questions as I replaced the water heater last weekend. It sits adjacent to the furnace, which has a discrete Edison fuse; I don't recall if that was part of the litany but it probably was.
I think the quote probably comes from "The Demon-haunted World" but I read it a very long time ago so I may be wrong.
“Smaller dodecahedra with the same features (holes and knobs) and made from gold have been found in South-East Asia along the Maritime Silk Road. They have been used for decorative purposes and the earliest items appear to be from the Roman epoch.”
Perhaps not as prolific as the trade along the landed silk road, but there's a smattering of roman coins and artifacts all over SEA.
They made contact with China during Marcus Aurelius but then plague came back and the trade collapsed. I don't think roman trade went so far

which suggests a corslet being stiffened with "pale mountain bronze". Perhaps the "pale mountain bronze" is in the form of a dodecahedron? Then did a search for ancient images of women wearing toga's and found this:

Look at her shoulders. Maybe these dodecahedra were ornamental fasteners for clothing, with the different hole sizes allowing them to be used with different weights of fabric. So perhaps they were a fad fashion adornment for rich women (due to the cost of the precision manufacture). I could see the smaller ones being used as a weight attached to clothing to control the drape and accentuate the figure as well. Pull some cloth through it, tie a knot and it pulls on the cloth in a certain way. A hair ornament would make sense also, with the different sized holes allowing for pulling differing amounts of hair through the holes and knotting the hair to hold the ornament in place.
No one is certain why tribes all across planet in the midst of a pandemic and the a looming extinction became so obsessed with computer hardware that seemed to have achieved no practical function other than to perform intensive compute operations.
Some researchers suggest that these instruments had a special cultural significance, and perhaps even a religious function.
It hasn't gotten anywhere; I assume that's mostly because making assumptions tends to let you publish papers, while not making assumptions tends to stop you from publishing papers. There's no incentive in the system for accuracy.
It is unknown if Satoshi Nakamoto was in fact a real person, as there is there are no surviving primary sources or direct evidence of his existence.
So just as a guess, could that be used to smoothen some rods, like arrows or spires? It would be rather a manual tool, like a sanding block.
Another guess, is some kind of junction holder. Like a wheel/spokes hub or some sliding rope knot in harnesses, or tent-pitching aid.
Made of bronze there must be some reason for durability, hardness, water contact?
