When our personage decided to live in Italy, he changed his name and continued his profession as writer and bookseller. On the other hand he also worked himself up to an expert in another profession and so became a very famous man in Rome. Due to his great ability to move in the influential cultural spheres of social life in Rome and other Italian places he was informed about all new books and so we see that he was involved in the translation of various Italian books which then found their market in Spain. Everything comes to an end and so he had to escape to other places after the sack of Rome. He survived the sack. However, he was not sure about his life and therefore our mysterious author adopted another pseudonym and continued working in his field in his new residence. There he had old friends and was soon back in the highest cultural sphere. In the meantime he became older and decided to return to Spain. There we see him again involved in several books, because books were his life.
