NOTE
The story of Zorzi Ballarin and Marietta Beroviero is not mere fiction, and is told in several ways. The most common account of the circumstances assumes that Zorzi actually stole the secrets which Angelo Beroviero had received from Paolo Godi, and thereby forced Angelo to give him his daughter in marriage; but the learned Comm. C.A. Levi, director of the museum in Murano, where many works of Beroviero and Ballarin are preserved, has established the latter's reputation for honourable dealing with regard to the precious secrets, in a pamphlet entitled "L'Arte del Vetro in Murano," published in Venice, in 1895, to which I beg to refer the curious reader. I have used a novelist's privilege in writing a story which does not pretend to be historical. I have taken eleven years from the date on which Giovanni Beroviero wrote his letter to the Podestà of Murano, and the letter itself, though similar in spirit to the original, is differently worded and covers somewhat different ground; I have also represented Zorzi as standing alone in his attempt to become an independent glass-blower, whereas Comm. Levi has discovered that he had two companions, who were Dalmatians, like himself. There is no foundation in tradition for the existence of Arisa the Georgian slave, but it is well known that beautiful Eastern slaves were bought and sold in Venice and in many other parts of Italy even at a much later date.
