This, together with his expression and general air of composure, gave him a look of precocious maturity. His profile was serene and dignified. Unlike the other player, he was dressed not in sumptuous court clothes, but in a simple leather cuirass, with a gorget of burnished steel that gave him an unmistakably military air. He was leaning further over the chessboard than his opponent, as if concentrating hard on the game, apparently oblivious to his surroundings, his arms folded on the edge of the table. His concentration could be seen in the faint, vertical lines between his eyebrows. He was looking at the pieces as if they were confronting him with a particularly difficult problem whose solution required every ounce of intellectual energy. The inscription above his head read: RUTGIER AR. PREUX.

The lady sitting next to the window was set apart from the two players by the use of a sharp linear perspective that situated her on a higher plane within the picture. The black velvet of her dress, to which the skilled application of white and grey glazes added volume, seemed to come out of the painting towards you. Its realism rivalled even the painstaking detail of the carpet border, the precision in the painting of the tiled floor, every knot, joint and grain of the ceiling beams. Leaning towards the painting to study these effects more closely, Julia felt a shiver of professional admiration run through her. Only a master like Van Huys could have used the black of a gown to such advantage, employing colour created out of the absence of colour to an extent few would have dared. Yet it was so real that Julia felt that at any moment she would hear the soft swish of velvet on the embossed leather of the low stool.

She looked at the woman’s face. It was beautiful and, in the fashion of the time, extremely pale. Her thick blonde hair, carefully smoothed back from her temples, was caught up beneath a toque of white gauze. Her arms, sheathed in light grey damask, emerged from loose sleeves; her hands, long and slender, held a book of hours.
