“Oh, yes,” the shopkeeper said immediately. Short and wiry, with white hair and a quick smile, he opened a drawer behind him and pulled out several scrolls of paper. He unrolled one of them and showed Anna the drawing.

“See? Fourteen districts.” He pointed to the loosely triangular shape drawn in black ink.

“This is Mese Street, going this way.” He showed them on the map. “There’s the Wall of Constantine, and west of that again the Wall of Theodosius. All except district thirteen, across the Golden Horn to the north. That’s called Galata. But you don’t want to live there. That’s for foreigners.” He rolled it up and passed it to her. “That will be two solidi.”

She was taken aback and more than a little suspicious that he knew she was a stranger and was taking advantage. Still, she passed over the money.

They walked the length of Mese Street, trying not to stare around them like the provincials they were. Row after row of merchants’ stalls lined the street. They were shaded by canopies of every color imaginable, tied tightly to wooden posts to anchor them against the wind. Even so they snapped loudly in every gust, as if they were alive and struggling to get free.

In district one there were spice merchants and perfumers. The air was redolent with their wares, and Anna found herself drawing in her breath deeply to savor them. She had neither time nor money to waste, but she could not help gazing at them, lingering a moment to admire their beauty. No other yellow had the depth of saffron, no brown the multitoned richness of nutmeg. She knew the medical values of all of them, even the rarest, but at home in Nicea she had had to order them specially and pay extra for their freight. Here they were laid out as if they were commonplace.
