And to find and bring one other man.

Rustem of Kerakek, son of Zorah, sat cross-legged on the woven Ispahani mat he used for teaching. He was reading, occasionally glancing up to observe his four students as they carefully copied from one of his precious texts. Merovius on cataracts was the current matter; each student had a different page to transcribe. They would exchange them day by day until all of them had a copy of the treatise. Rustem was of the view that the ancient Trakesian's western approach was to be preferred in treatment of most-though not all-issues relating to the eye.

Through the window that overlooked the dusty roadway a breeze entered the room. It was mild as yet, not unpleasant, but Rustem could feel a storm in it. The sands would be blowing. In the village of Kerakek, below the fortress, the sand got into everything when the wind came from the desert. They were used to it, the taste in their food, the gritty feel in their clothing and bed sheets, in their own intimate places.

From behind the students, in the arched interior doorway that led to the family quarters, Rustem heard a slight rustling sound; he glimpsed a shadow on the floor. Shaski had arrived at his usual post beyond the beaded curtain, and would be waiting for the more interesting part of the afternoon lessons to begin. His son, at seven years of age, showed both patience and a fierce determination. A little less than a year ago he'd begun dragging a small mat of his own from his bedroom to a position just outside the teaching room. He would sit cross-legged upon it, spending as much of the afternoon as he was allowed listening through the curtain as his father gave instruction. If taken away by his mothers or the household servants he would find his way back to the corridor as soon as he could escape.

Rustem's two wives were both of the view that it was inappropriate for a small child to listen to explicit details of bloody wounds and bodily fluxes, but the physician found the boy's interest amusing and had negotiated with his wives to allow Shaski to linger outside the door if his own lessons and duties had been fulfilled. The students seemed to enjoy the boy's unseen presence in the hallway as well, and once or twice they'd invited him to voice an answer to his father's questions.
