Licinius used to swoon about vellum—parchment made from the skin of a calf cut out of the womb of its mother before it was born. He said that to write on vellum was like hearing the finest music, but the membrane from which these books are made feels coarse and bristly and smells like rancid broth. Himerius is right: these will be worth nothing at all.

A maidservant comes past carrying a basin of milk, taking small steps so as not to spill it, and the hunger in Anna’s gut is enough to make the courtyard swim. She has failed again. Widow Theodora will beat her with the bastinado, Himerius will denounce her for stealing chickens from the convent, Maria will never have enough silver for a blessing from the shrine of the Virgin of the Source, and when Anna’s body swings from the gibbet the throngs will say alleluia.

How does a life get to be like this? Where she wears her sister’s castoff underlinen and a thrice-patched dress while men like Kalaphates go about in silk and velvet with servants trotting behind? While foreigners like these have basins of milk and courtyards of geese and a different coat for every feast day? She feels a scream building inside her, a shriek to shatter glass, when Himerius hands her a small battered codex with clasps on the binding.

“What’s this?”

She opens to a leaf in the middle. The old Greek Licinius taught her proceeds across the page line after systematic line. India, it reads,

produces horses with one horn, they say, and the same country fosters asses with a single horn. And from these horns they make drinking-vessels, and if anyone puts deadly poison in them, and a man drinks, the plot will do him no harm.

On the next page:

The Seal, I am told, vomits up the curdled milk from its stomach so that epileptics may not be cured thereby. Upon my word the Seal is indeed a malignant creature.

“This,” she whispers, her pulse accelerating. “Show them this.”

Himerius takes it back.

“Hold it the other way. Like so.”

The boy kneads the great orbs of his eyeballs. The lettering is beautiful and practiced. Anna glimpses, I have heard the people say that the Pigeon is of all birds the most temperate and restrained in its sexual relations—is it a treatise about animals?—but now the clubfooted servant calls to Himerius and he takes the book and sack and follows the servant into the house.

The geese watch her.

Himerius is not gone fifty heartbeats before he comes back out.

“What?”

“They want to speak to you.”
