Worldbuilding: How the Jokka Count
As I’m not a numbers person I rarely think about counting systems for worlds I’m building. In practice, when you're writing you don't often get into math. But if I was going to, the world of the Jokka would be a good target. So many of the Jokka I’ve written are either superlative organizers or impressive account-keepers... at least one was so good at business, it shaped the world, and another, in the recent novella, was actually making some of the first Jokku abacuses!
Despite this obvious opportunity, I didn’t think about number systems for them until I was drawing a clay tablet for the game and realized it needed scribbling on it. So I started scribbling. And once I started scribbling, I started thinking it through.
So here’s how the Jokka count, and how I walked through that process.
They have claws, which are great for making lines in clay (their first substrate for writing). So I went with the same kind of bars we’d find familiar: vertical swipes.
Then I thought about why a nomadic world might care about numbers, and that’s when I came up with animals. Because your wagons are pulled by them, and you have little goat-equivalents (the midena) for milk, and if you have more than a couple, you have to stop staking them down individually and build a corral.
So – 1-2-3-4 and then “pen them” for five by hooking a wall around them.
Note that I establish in the stories that Jokku writing is boustrophedon, which means it is read in a snake-like fashion: you read to the end of one line then immediately look down at the “end” of the second line and go backwards to the “front”. So numbers can be penned from the right or the left; it doesn’t matter which.
After you pen five animals, you need to build them serious shelter if you have more. So after that, you “roof” them for ten. That gets all ten of your fingers involved.
Then the abacus comes along, and “penning” and “roofing” becomes an indicator of the decimal place. Penning something multiplies its interior by five; roofing by ten. Housing a number (encircling it) moves it a decimal place further: “You need the whole abacus to calculate this number, roof, floor, and walls!”
This means there’s probably sayings based on math (“roof, floor, and walls” is probably one of them, and would mean something like “a ton of stuff” or “an overflowing bounty”). But the one thing I definitely caught is gestures: a thumbs-up for a Jokkad is “give me five of those”, while a palm either facing down or up can be “fill this” (give me ten). These gestures are holdovers from before the abacus, so they don’t indicate multipliers!
I had talked myself into an evolution of how people write and talk based on technology, at this point. (Which is cool, because that does happen.) And since I’m not planning to write any mathematicians, I probably won’t take it any further than this. But it was fun to get this far, and I’ve included, above, the sketchbook page where I doodled my way into this idea…!
And now, if you play the game, you know that the scratches on the tablets have meaning!
