the wrestling cats of the Drazhada worked into the brocade suggested he must be in one of his father's households, but...
Brocade is a very interesting fabric.
Brocade is woven, and the way woven fabric works, generally, is that the vertical threads are fed through the mechanism of the loom, then raised and lowered in groups. As you raise a group of threads, you pass one line (called a pick) of horizontal thread through it. Then you lower the first group of warp threads and raise the second. When you''re making very basic plain weave, there's just 2 groups, the odd and the even threads. This determines the picture, because raised threads are visible on the surface of the fabric, while lowered threads are on the underside. I work with a 4 shaft loom, so I have 4 different groups that can be raised or lowered (either shaft by shaft or in pairs and trios. That gives me enough flexibility to make diamonds, squares, and some undulating and zig-zag lines. More complicated looms sold for hobby weavers will give you 8 or 16 groups and those patterns can be more complex.
But to make images as complicated as wrestling cats, you would need dozens or even hundreds of different orders of threads raised and lowered. So, historically, what was instead used was a draw loom which rather than having a huge number of shafts you just raised and lowered each thread independently, for each line of thread in the fabric. This required two weavers. One to raise and lower the threads, one to weave. A really good draw loom team could weave brocade at a rate of about an inch a day (Essinger, James (2004) Jacquard's Web. Oxford University Press, Oxford UK pg 16 - 17).
This all changed with the invention of the Jacquard Loom. The Jacquard loom stores the pattern in punch cards, one card per row, and once the cards are loaded onto the loom the pattern of raised and lowered threads is determined by the cards (the mechanism for raising the threads literally rises through the holes in the binary punch cards). This totally changes the cost and availability of luxury fabrics, because on a Jacquard Loom, that same complicated brocade can be made by one weaver, at about 24 inches per day (Essigner, James (2004) Jacquard's Web. Oxford University Press, Oxford, UK pg 38).
The punch card mechanism from the Jacquard Loom, is the directly ancestor of punch card computing, which is where we get all modern binary computing from.
So what do we think guys?
How are they making brocade in the Ethuveraz?
1 inch/day, we're still in the land of strictly handmade textiles.
They have punch card looms and the technological implications are looming.
So we've got steam engines and we've got large textile mills/factories. The preconditions for someone to invent the jaquard loom are there.
I was going to say 'also at 1 inch/day I would expect such a brocade to be used for formal clothing, possibly a robe or something. i.e. seen publicly, whereas bed hangings are a LOT more fabric even than full floor-length robes or a cloak with a train, AND they would only be seen by the emperor, his servants and nohecherei, and perhaps his wife and/or mistress. Despite the reference to 'gentlemen of the bedchamber' the eudocharei are straight up servants, they're not an aristocratic buffer between the emperor and the lower servants.
But then I remembered... the Tethimada sharadansho silk bed hangings. Maybe if you're only replacing the bed-hangings (a low wear situation) once every several decades you DO use the 'each yard is a month's work for two laborers' fabric for a purely private luxury?
Essinger specifically references curtains as something produced over many months the old-fashioned way, but those are more public than bed-hangings. So I have no idea. I'm not a historian, this is my only source for this.
