the smallest possible space, in the fashion of that time.  There was often a little colour in her face, though never much, and it was faint, yet very fresh, like the tint within certain delicate shells; her lips were of the same hue, but stronger and brighter, and they were very well shaped and generally closed, like her father’s.  But her eyes were not like his, and the lids and lashes shaded them in such a way that it was hard to guess their colour, and they had an inscrutable, reserved look that was hard to meet for many seconds.  Zorzi believed that they were grey, but when he saw them in his dreams they were violet; and one day she opened them wide for an instant, at something old Beroviero said to her, and then Zorzi fancied that they were like sapphires, but before he could be sure, the lids and lashes shaded them again, and he only knew that they were there, and longed to see them, for her father had spoken of her marriage, and she had not answered a single word.

When they were alone together for a moment, while the old man was searching for more materials in the next room, she spoke to Zorzi.

“My father did not mean you to hear that,” she said.

It happened now and then that Marietta did not come to the glass-house.  Those days were long, and when night came Zorzi felt as if his heart were turning into a hot stone in his breast, and his sight was dull, and he ached from his work and felt scorched by the heat of the furnace.  For he was not very strong of limb, though he was quick with his hands and of a very tenacious nature, able to endure pain as well as weariness when he was determined to finish what he had begun.  But while Marietta was in the laboratory, nothing could tire him nor hurt him, nor make him wish that the hours were less long.  He thought therefore of what must happen to him if Jacopo Contarini took Marietta away from Murano to live in a palace in Venice, and he determined at least to find out what sort of man this might be who was to receive for his own the only woman in the world for whose sake it
