Paulus Orosius, less often Paul Orosius in English, was a Roman priest, historian and theologian, and a student of Augustine of Hippo. It is possible that he was born in Bracara Augusta, then capital of the Roman province of Gallaecia, which would have been the capital of the Kingdom of the Suebi by his death. Although there are some questions regarding his biography, such as his exact date of birth, it is known that he was a person of some prestige from a cultural point of view, as he had contact with the greatest figures of his time such as Augustine of Hippo and Jerome of Stridon. In order to meet with them Orosius travelled to cities on the southern coast of the Mediterranean Sea, such as Hippo Regius, Alexandria, and Jerusalem.
These journeys defined his life and intellectual output. Orosius did not just discuss theological matters with Augustine; he also collaborated with him on the book City of God. In addition, in 415 he was chosen to travel to Palestine in order to exchange information with other intellectuals. He was also able to participate in a Church Council meeting in Jerusalem on the same trip and he was entrusted with transporting the relics of Saint Stephen.
