the oldest fidget toy we know about

in 2017 the world spent about a year losing its mind over the fidget spinner. plastic, bearings, three lobes. adults bought them. schools banned them. eighteen months later they were in a drawer.

a lot of columns got written about what this said about the modern attention span.

the modern attention span had nothing to do with it. we have been carrying these for three thousand years. we used to make them out of stone and call it equipment.

it started as armour

if you shoot a bow the european way, you draw the string with three fingers. if you shoot it the chinese way — and later the manchu way, from a horse — you hook the string over your thumb.

which works, and hurts. a loaded bowstring against bare skin will open it.

so you put a thick ring on the thumb, with a groove running underneath. the string sits in the groove, and when you release, it leaves clean instead of dragging across you.

the old name for it is 韘 (shè). around the year 100, the scholar xu shen defined it in china's first character dictionary as a device for hooking the bowstring, made of ivory, bone or leather, tied onto the right thumb.

that is a tool entry. it reads like a line from a catalogue of workshop equipment, which is what it was.

and it was ordinary. there's a line in the book of songs, the oldest poetry collection in chinese, that goes “the leaves of the wan-lan vine — the boy wears a shè.” not a general. not a duke. a boy, one who had learned to shoot and to drive a chariot. everybody who used a bow had one.

the oldest one we have belonged to a general

here is a thing worth knowing about archaeology: most people's thumb rings were leather, and leather does not last three thousand years. so the ones we dig up are almost exclusively the jade ones — the ones belonging to the small number of military commanders whose rank came with jade.

what survives is not what was normal. what survives is what was expensive.

the earliest known jade one came out of the tomb of fu hao at yinxu, in henan province. she was a consort of king wu ding of the shang dynasty, and she died around 1200 BCE.

fu hao was not decorative. oracle bone records have her commanding armies; the largest campaign recorded under her name ran to thirteen thousand troops. her tomb was found intact in 1976 with hundreds of bronzes and around 590 jades in it.

her ring is dark green with brown flecks. hollow, cylindrical, sized for an adult thumb. the top is cut on a slant, high at the front and low at the back. there's an animal mask carved on the face, with two small holes beneath it for a cord. a groove runs down the lower back to take the bowstring.

and the bowstring left marks on it. you can still see where it wore.

that's the part i can't get past. thirty-two centuries, and the object still carries the evidence that somebody used it. it wasn't buried with her as a symbol of anything. it was her kit.

at least six more, near-identical in form, came out of a western zhou cemetery at sanmenxia. the design worked, so it stopped changing.

then everybody stopped shooting

the qing dynasty was founded by manchus who took the country on horseback with bows, and they were extremely conscious of it.

every banner boy trained at his banner's archery hall before he turned twenty. you started at “one strength” — roughly ten kilos of draw — and worked up. twenty strengths. some of them thirty. you wore a thumb ring every time you drew, so essentially every man in that class owned one, and owning one became a tradition rather than a decision.

somewhere along the way the formal word 韘 got replaced in daily speech by the plainer 扳指 (banzhi) — near enough to “the thing you pull with.”

and then the empire settled down. the campaigns thinned out. within a few generations the banner families' actual archery had gone soft.

the ring stayed.

it turned into one of the most fashionable things a man could wear — emperors, princes, ministers, banner sons, and eventually any merchant with the money. the material inflated accordingly: from leather and rhino horn and camel bone up to ivory, rock crystal, jade, porcelain, jadeite. prices went with it. in a novel published at the end of the dynasty, a character's jadeite thumb ring is worth nine hundred taels of silver.

nine hundred taels, for a piece of archery equipment, worn by a man who could not draw a bow.

the emperor who wrote fifty poems about one

the qianlong emperor could actually ride and shoot, and for that he wore working rings — horn and ivory, practical materials. you can see them on him in two paintings still in the palace museum.

in the qianlong emperor's grand review, painted by giuseppe castiglione in 1739, he's in full ceremonial armour on a horse, and if you go in close on the hand resting by the bow case there's a plain cream band around the thumb. no carving. no decoration. it's equipment.

the other one is taking a deer with a mighty bow, by an anonymous court painter. he's caught at the instant of release — the fingers of the drawing hand still open, the arrow already gone. there's a ring on that thumb too, and this one is green.

the jade ones were a separate matter.

in the spring of 1752 someone brought him a jade thumb ring. the workmanship was fine and the stone was exceptionally smooth, and he liked it enough that he wrote a poem about it — comparing bone and ivory rings, which merely “pass down antiquity,” to jade, which he called warm, virtuous, and fit to be a teacher.

a few months later he wrote a second poem about the same ring.

over the next forty-five years he wrote no fewer than fifty poems about jade thumb rings.

fifty. about a hoop of stone that goes on a thumb. by a man running an empire.

and he didn't leave them on paper. he had them carved onto the rings, around the outside, so the object was wearing the poem about itself. one of his phrases for the thing was the bow and arrow as a lesson in governing — which is a lot to ask of an object you have stopped using for its job.

the surviving ones are small. about 3cm across, 2.5cm tall. that's the size of the whole argument.

i find that reassuring rather than absurd. somebody at the very top of the largest state on earth, with unlimited access to everything, sat there turning a rock and then wrote about it fifty times over four decades. he was not solving a problem. he had the same hands you do.

what didn't change

between fu hao around 1200 BCE and an emperor at a desk in 1752, the object is essentially unchanged: a heavy ring, wider than a normal one, loose enough on the thumb to turn.

the reason changed completely. the behaviour did not.

hers had wear marks from a bowstring. his had a poem. same shape, same hand, same fidget.

that is a very long and very consistent data set on what human hands want. they want something in them. preferably heavy, preferably cold, preferably something that turns.

the spinner wasn't new. we'd just forgotten the older one.

the physical part, without the mysticism

i'm not going to tell you a stone fixes your nervous system. i'll tell you what a rock actually does, because it's measurable.

thermal mass. natural stone takes body heat slowly and dumps it fast the moment you set it down. plastic reaches your hand's temperature in seconds and stays there. neither is better; they're just different things to hold. what stone gives you is that it's cold again every time you pick it up.

weight. three of the four run about 45g — roughly an egg. more than you expect from something that size, and the surprise is most of the appeal. the fourth, the xiuyu, is 18g, which is a different tool entirely.

the loose fit is the design, not a defect. inner diameter 22–23mm (about 0.9 in). this is archery geometry, not a wedding band. loose is what lets you spin it on your index finger with your thumb, which is the actual motion.

heads up, and it's a real one: loose also means it comes off. when you're not playing with it, put it on a cord. people lose these.

what's in the shop

four of them, all stone, all hand-finished, none of them a rare mineral. i'll say that plainly because somebody is going to ask: 'jade' here is the chinese sense of the word, and these are not hetian nephrite. they're stone from a named place, cut for a thumb.

• the bianstone ring — $14.99. black, matte, dense. one of the older stones in chinese medicine. cool against skin and stays that way.
• the lantian jade ring — $19.99. lantian is a town outside xi'an, which is where i'm from. growing up the stone was just around the house — buddhas, teacups, a cooling pillow somebody's relative gave us. i didn't pick it for any property it supposedly has. i picked it because it's the rock from home.
• the magnetic ring — $24.99. tibetan serpentine, naturally magnetic. it moves a compass needle. that's the entire claim, and i think it's enough.
• the xiuyu jade ring — $29.99, and the only one where the money buys you something you can see. the markings don't sit in bands or veins the way they do in most stone — they spread and pool, closer to splashed-ink painting than to a pattern, and no two come out the same. it's also the light one, and not by a little: 18g against 45g, narrower with it. it spins faster, and it's the one you stop noticing you're wearing. grey on some, dark green on others.

each is hand-finished, so no two are identical.

none of them will ever meet a bowstring. neither did the emperor's.

go play.
