an ancient method of writing in which the lines run alternately from right to left and from left to right.
Or, as said in the book, top to bottom then bottom to top. This is important, because my constructed language Dven'bahnis (for the Traipahni language) uses this second kind of boustrophedon. In fact, it starts at what we would normally consider the *back* of the book, on the right side, goes up the right side, then down the line left of that line. So it's a top-bottom oriented boustrophedon that moves to the left. Turn the page, and you start at the lower right corner again.
I think only one of my novels has any Traipahni writing in it, and that one is unfinished. It's a sign, and does the English left-to-right. But Traipahni culture is often slow to change and cherishes ancient knowledge, so until a certain point in their history when they invented books, they used scrolls. In fact, a lot of their old knowledge is still copied onto scrolls AS WELL AS into books. And I've decided that their scroll writings are somewhat similar to how Dven'bahnis is written on book pages. But it wouldn't be a top-bottom oriented boustrophedon! It would start in the lower right corner, move to the left, then go from left to right, then right-left, so on and so on. So still a boustrophedon, just oriented differently. And it would start at what we would consider the end of the scroll and work its way upward.
The Ah'Koi Bahnis also do unusual forms of writing for ritual purposes sometimes, writing in spirals or star shapes or other unusual shapes. Oooh, and I just got this image in my mind of a form of poetry that... well... I'm not sure how to describe. I'll have to see if I can do one, so I can show y'all.
All for now.
EDIT = Okay, upon checking, Dven'bahnis as written in books is NOT a boustrophedon. It's bottom-top, bottom-top, bottom-top in a leftward direction.
