"The similitude is a good one," said Daniel Waterhouse. "Yes, now you are in another court full of Dervishes, as queer in their own way, yet as easy around their own kind, as those you spied in Constantinople." He and Eliza had paused in a relatively stagnant corner of the court. Above them, a beam had been thrown across a gap to make a lifting-point. Suspended from its middle was an elephant’s tusk, an ivory crescent eight feet in diameter if it was an inch. Diverse clever baffles and charms had been fixed to its rope to prevent rodents from abseiling down for midnight picnics; the only creature allowed to gnaw at this treasure was a journeyman ivory-carver who was having at it with a fine-toothed saw. Nor was this the only oddity or wonder in the Court of Technologickal Arts. The yard was an irregular pentagon a hundred feet in breadth. It was closed in by an arcade of work-stalls, each little more than a lean-to sheltering some odd collection of tools. At a glance Eliza saw a glass-blower, a goldsmith, a watch-maker, and a lens-grinder, but there were many others who had their own collections of specialized lathes, mills, hand-tools, and paraphernalia that were every bit as particular, especial, and jealously looked-after. Perhaps that old Jew with the stubby telescopes strapped to his face had once called himself a jeweler, and the obese German overflowing yon tiny stool had been a toy-maker, turning out music-boxes. Now whatever they did had been subsumed in a larger and more obscure purpose. Others simply could not be classified at all. There was a bloke who had a stall to himself, off in the corner—an exile even among Dervishes—where he had mounted a glass sphere on an axle. Spinning this around with the aid of a wan, jittery apprentice, he produced unearthly crackling noises and summoned forth small lightning-bolts.
