When she died, he said little, but he would not allow his own children to speak of her before him.

After that, he became almost as jealous of his daughter, and though he did not lock her up like her mother, he used to take her with him to the glass-house when the weather was not too hot, so that she should not be out of his sight all day.
Moreover, because he needed a man to help him, and because he was afraid lest one of his own caste should fall in love with Marietta, he took Zorzi, the Dalmatian waif, into his service; and the three were often together all day in the room where Angelo had set up a little furnace for making experiments.

In the year 1470 it was not lawful in Murano to teach any foreign person the art of glass-making; for the glass-blowers were a sort of nobility, and nearly a hundred years had passed since the Council had declared that patricians of Venice might marry the daughters of glass-workers without affecting their own rank or that of their children.

But old Beroviero declared that he was not teaching Zorzi anything, that the young fellow was his servant and not his apprentice, and did nothing but keep up the fire in the furnace, and fetch and carry, grind materials, and sweep the floor.

It was quite true that Zorzi did all these things, and he did them with a silent regularity that made him indispensable to his master, who scarcely noticed the growing skill with which the young man helped him at every turn, till he could be entrusted to perform the most delicate operations in glass-working without any especial instructions.
