So I realized this morning that I own seven books about a single 13-episode TV show that was cancelled more than 20 years ago. And that made me feel slightly insane and obsessive.
And then I remembered that I can only own seven books about Crusade because people out there published seven books about Crusade, presumably on the grounds that a) they wanted to, and b) they thought more than one person would buy them.
That didn’t make me feel less insane or obsessive, but it did make me feel happy to have company.
There was this woman poet in 4th century China called Su Hui (蘇蕙), a child genius who had reportedly mastered Chinese characters by age 3.
At 21 years old, heartbroken by her husband who left her for another woman, she decided to encode her feelings in a structure so intricate, so beautiful, so intellectually staggering that it still baffles scholars to this day.
Came to be known as the Xuanji Tu (璇璣圖) - the “Star Gauge” or “Map of the Armillary Sphere” - it’s a 29 by 29 grid of 841 characters that can produce over 4,000 different poems.
Read it forward. Read it backward. Read it horizontally, vertically, diagonally. Read it spiraling outward from the center. Read it in circles around the outer edge. Each path through the grid produces a different poem - all of them coherent, all of them beautiful, all of them rhyming, all of them expressing variations on the same themes of longing, betrayal, regret, and undying love.
The outer ring of 112 characters forms a single circular poem - believed to be both the first and longest of its kind ever written. The interior grid produces 2,848 different four-line poems of seven characters each. In addition, there are hundreds of other smaller and longer poems, depending on the reading method.
At the center a single character she left implied but unwritten: 心 (xin) - “heart.” Later copyists would add it explicitly, but in Su Hui’s original the meaning was even more beautiful: 4,000 poems, all orbiting the space where her heart used to be.
Take for instance the outer red grid of the Star Gauge. Starting from the top right corner and reading down, you get this seven-character quatrain:
仁智懷德聖虞唐，
貞志篤終誓穹蒼，
欽所感想妄淫荒，
心憂增慕懷慘傷。
In pinyin, it is:
Rén zhì huái dé shèng yú táng,
zhēnzhì dǔ zhōng shì qióng cāng,
qīn suǒ gǎnxiǎng wàng yín huāng,
xīn yōu zēng mù huái cǎn shāng.
Notice how it rhymes? táng / cāng / huāng / shāng
The rough translation in English is: “The benevolent and wise cherish virtue, like the sage-kings Yao and Shun, With steadfast will I swear to the heavens above, What I revere and feel - how could it be wanton or dissolute? My heart’s sorrow grows, longing brings only grief.”
Now read it from the bottom to the top and you get this entirely different seven-character quatrain:
傷慘懷慕增憂心，
荒淫妄想感所欽，
蒼穹誓終篤志貞，
唐虞聖德懷智仁。
The pinyin:
Shāng cǎn huái mù zēng yōu xīn,
huāngyín wàngxiǎng gǎn suǒ qīn,
cāngqióng shì zhōng dǔzhì zhēn,
táng yúshèngdé huái zhì rén.
It rhymes too: xīn and qīn, zhēn and rén
And the meaning is just as beautiful and coherent: “Grief and sorrow, longing fills my worried heart, Wanton and dissolute fantasies - is that what you revere? I swear to the heavens my constancy is true, May we embody the sage-kings’ virtue, wisdom, and benevolence.”
That’s just 2 poems out of the over 4,000 you can construct from the Xuanji Tu!
At the very center of the grid, the 8 red characters wrapped around the central heart, she “signed” her poem with a hidden message:
詩圖璇玑，始平蘇氏。 “The poem-picture of the Armillary Sphere, by Su of Shiping.”
Or reversed:
蘇氏詩圖，璇玑始平。 “Su’s poem-picture - the Armillary Sphere begins in peace.”
Many scholars, and even emperors, throughout Chinese history have been completely obsessed by Su Hui’s puzzle.
For instance, in the Ming dynasty, a scholar named Kang Wanmin (康萬民) devoted his entire life to the poems (kangshiw.com/contents/461/2…), ending up documenting twelve different reading methods - forward, backward, diagonal, radiating, corner-to-corner, spiraling - and extracting 4,206 poems. His book on the subject (“Reading Methods for the Xuanji Tu Poems”, 璇璣圖詩讀法) runs to hundreds of pages.
Empress Wu Zetian herself, the legendary woman emperor of the Tang dynasty, wrote a preface to the Xuanji Tu around 692 CE (baike.baidu.com/item/%E7%BB%87…).
Incredibly, there’s even far more complexity to the Xuanji Tu than just the poems:
- The name 璇玑 (Xuanji) - Armillary Sphere - is astronomical in meaning and the way the poems can be read mirrors the way celestial bodies orbit around a fixed center. It’s a model of the heavens.
- Her original work, with the characters woven on silk brocade, was in five colors (red, black, blue/green, purple, and yellow) which correspond to the Five Elements (五行) - the foundational Chinese philosophical system that explains how the universe operates. So it’s also a model of the entire cosmic order according to ancient Chinese philosophy.
- It’s also of course deeply mathematical with this 29 x 29 perfect square grid, with sub-squares, lines and rectangles, and a structure which allows for symmetrical reading patterns in all directions
- Last but not least, the content of the poems themselves contain multiple registers. On top of expressing her personal grief and longing for her husband, it’s also filled with accusations against the concubine (Zhao Yangtai) he left her for, reflections on politics (with many references to sage-kings) and philosophical reflections.
So the Star Gauge is simultaneously:
- A love letter (expressing personal longing)
- A legal brief (arguing her case against her rival)
- A cosmological model (structured like the heavens)
- A Five Element diagram (encoding the fundamental structure of the world according to ancient Chinese philosophy)
- A mathematical construction with perfect symmetry and precision
And yet, for all this complexity, we should not forget this was all ultimately in service of the simplest human message imaginable: a 21-year-old woman asking the love of her life “come back to me”.
Her husband did, eventually. According to what empress Wu Zetian herself wrote in her preface to the Xuanji Tu, when he received Su’s brocade he was so “moved by its supreme beauty” that he sent away his concubine and returned to his wife. As the story goes, they lived together until old age.
The heart at the center was filled after all.
I wish I could travel through time and transcend language to hold this woman’s hand and tell her “girl, he ain’t shit”
Me for the last 15 years: Starting a timer when you have to wait for something or stand in line can be helpful, because no matter how impatient you feel you can check the timer and remind yourself it has not been several eternities and has in fact only been five minutes.
Me setting a timer when I got to bag claim just now: I’m so clever! I will now be reminded that it’s only been five minutes and bag claim usually takes about twenty!
Me looking at the timer thoughtfully: …another Very Neurotypical Moment With Sam, it appears.
FTR it was 17 minutes from “arriving at the bag claim” to claiming my bag, so right on time.
Someone tagged this post “#it’s all fun n games until baggage check takes over an hour” which is 100% legit; a common sentiment in notes is that sometimes you don’t want to know how long something has taken. But that is one of the reasons I started doing the stopwatch thing in the first place!
On the one hand, timing something is about reminding myself “No, it’s only been five minutes,” but it is ALSO about knowing when something is taking way longer than it should.
If I’m put into an exam room in a doctor’s office, I start a timer. Because I have been forgotten about in a doctor’s office before, I get nervous that I’ll just be sat in there forever, and the timer tells me “No, they haven’t forgotten you, it’s only been 10 minutes.” But it also tells me if I have been there longer than appropriate (generally more than 40 minutes) so that I know when it’s justifiable to flag down a nurse to find out what’s going on.
At bag claim, because I know it usually takes about 20 minutes to get my bag, I don’t get concerned until the timer passes the 20 minute mark without any bags appearing. At that point I know I need to take off my headphones and start paying attention – looking at signage, maybe asking someone if I’m at the right carousel. Maybe don’t worry yet, but start double-checking. Perhaps the delay is unavoidable and it’ll just be an hour, but at least, having asked, I KNOW it’ll be an hour, and the timer will tell me when the hour is past and I should maybe check in again.
Now, if the bags do start showing up before 20 minutes but my bag hasn’t shown up by the 40 minute mark, I know that again it’s time to put my head on a swivel, and at the 50 minute mark it’s time to go speak to someone in the baggage claim office. This has more than once helped me locate my bag when it’s accidentally been sent to the wrong part of the airport. There is no point at which, without the timer, I would go “man this is taking a long time” and then actually go ask, because I wouldn’t actually know how long it had been.
The timer both prevents me from worrying before I need to and tells me when to start worrying – essentially, because I’m both perpetually impatient and also infinitely patient, I’ve outsourced my patience to a stopwatch. And because I time a lot of things, I now know the average time a lot of things take, which helps me calibrate my concerns appropriately. Ten minutes is a long time to wait for a burger from McDonalds, but it’s actually on the short end of the time it takes to get a burger from Shake Shack. It’s not a long time to be on hold with the HR office of my old employer, but it’s longer than I’d usually be on hold with my pharmacy. Et cetera.
I know I say this all the time but I still find it hilarious that I didn’t know I had ADHD until I was forty years old.
just want to add that I’ve started timing myself doing everyday chores and tasks and having a more realistic, personalized idea of how long things take has helped a lot with my time blindness.
I only just started, and it’s not yet habitual, so there’s only a small bit of info, but it’s already made it easier to avoid rushing or getting stuck in waiting mode because it takes out a lot of the guesswork.
And it lets me have grace for myself when something is really taking it out of me. I’m right, this *is* taking forever and it isn’t usually this hard, so what’s going on? Do I need to rest? Eat? Did I forget my meds? Am I overwhelmed? Etc.
I feel like a scientist gathering and applying data.
Showers on typical days only take “about ten minutes” (me, 2025), therefore, I CAN shower before my appointment that’s two hours away.
Contrary to popular belief, doing a quick tidy takes “less than half an hour” (me, 2026) and will not take the better part of a day. I don’t need to dread or put it off because I can start a 20min episode and I’ll be done before the credits roll.
The proposed estimate of “10-30 miserable minutes in the cold when the warm blankets are right there” (time blindness and depression, 2024), is erroneous, and based on pre-medicated data. As tempting as it is to go straight back to bed after peeing, my research shows that brushing teeth, including “prep and cleanup,” rarely takes more than four minutes and may even improve morale and momentum when getting up for the day.
This is awesome and hey guess what: you ARE a scientist gathering and applying data!
I’m super proud of you and everyone who is working to keep their lives together in the face of disability and the general horrors of the world right now. Keep up the great work! And if things slip a little that’s ok too. None of us are perfect. Just keep taking notes…for SCIENCE!
