I was born in Constantinople; my father was a dragoman at the Porte, and besides, carried on a fairly lucrative business in sweet-scented perfumes and silk goods. He gave me a good education; he partly instructed me himself, and also had me instructed by one of our priests. He at first intended me to succeed him in business one day, but as I showed greater aptitude than he had expected, he destined me, on the advice of his friends, to be a doctor; for if a doctor has learned a little more than the ordinary charlatan, he can make his fortune in Constantinople. Many Franks frequented our house, and one of them persuaded my father to allow me to travel to his native land to the city of Paris, where such things could be best acquired and free of charge.
