A year after your departure I had the good fortune to secure the services
of a fine, generous, young lad, whom I am sorry you do not know. He knows
you well, for he has often seen you, at Venice, in your house, where I am
now living, and also at the home of our friend Donato, and on such
occasions has observed you very carefully, as is natural at his age. I
want you to know him, too, so far as that is possible at such long range,
and to see him with the mind's eye, when you read my letters, and so I
will tell you a little about him.
