After supper, Irene and Sophia washed the dishes in a basin of water. By the time they were done, full darkness had fallen. Against its almost palpable presence, the flames from the lamps and the flickering light they cast seemed tiny and weak, the next thing to lost. George thought of the Slavs and Avars moving down toward the Aegean, and of Thessalonica, a Christian light in a sea of pagan darkness.

He went to the window and looked out. Most of Thessalonica was dark now, with a glow of candles and of holiness coming from the churches, more lights up on the walls, and here and there one moving through the streets as prominent people undertook to travel through the night. Footpads traveled through the night, too, but did not advertise their presence.

“Close the shutters, George,” his wife said, yawning. “Let’s go to bed.” Few people--mostly the rich, who could afford the lamps and candles they needed to turn night into day--stayed up long past sunset. Nor was darkness the only reason for that. When you rose with the sun and worked hard all day, you were ready to go to bed by the time night came.

The room to the left of the hall as you walked up it had been shared by Sophia and Theodore. These days, since they’d come to puberty, it had a wooden partition down the middle that turned it into two cubicles. George kept telling himself--and anyone who would listen--he would enlarge the doorway one day soon. He’d been saying it for so long, he didn’t believe it himself anymore.

He used a lamp from the kitchen to light one that rested on a stool by the bed in his own bedchamber, then, in orderly fashion, carried the first one back to where it belonged, blew it out, and used what glow came through the doorway from the second to guide him up the hall.
