From the age of 17 to his early 20s, he intermittently studied medicine and theology in Oporto and Coimbra and eventually chose to become a writer. After a spell of journalistic work in Oporto and Lisbon he proceeded to the episcopal seminary in Oporto in order to study for the priesthood. During this period Camilo wrote a number of religious works and translated the work of François-René de Chateaubriand. Camilo actually took minor holy orders, but his restless nature drew him away from the priesthood and he devoted himself to literature for the rest of his life. He was arrested twice; the first time for having unearthed the remains of his first wife (whom he had married at the age of 16, and who had died at 24) and the second due to his adulterous affair with Ana Plácido, who was married at the time.
