The art of snaring pigeons is as follows. When the men who devote themselves to this craft have caught one, they tame it, and make it feed with them. Then they smear its wings with sweet oil, and let it go and join the rest outside. Then the scent of that sweet oil makes the free flock the possession of the owner of the tame bird, for all the rest are attracted by the fragrance, and settle in the house. But why do I begin my letter thus? Because I have taken your son Dionysius, once Diomedes, and anointed the wings of his soul with the sweet all of God, and sent him to you that you may take flight with him, and make for the nest which he has built under my roof. If I live to see this, and you, my honoured friend, translated to our lofty life, I shall require many persons worthy of God to pay Him all the honour that is His due.
