By the time he’d reached the forward part of the oar-deck, Jack had lost track of the light’s source—but then one more flash nicked him again, then faded and shrank to a little polygon of grey glass, held in a man’s fingers. Jack had already guessed it would be a hand-mirror, because these were commonly found among the few miserable effects that galley-slaves were allowed to have with them. By thrusting it out of an oar-lock, or raising it high overhead, the owner could see much that would otherwise be out of his view. But it was cheeky for a galérien to flash sunlight into the eyes of a free man standing in the aisle, because this was most annoying, and might be punished by breakage or confiscation of the mirror.
