Bracara Augusta in the context of "Porto Metropolitan Area"

Gallaecia, also known as Hispania Gallaecia, was the name of a Roman province in the northwest of Hispania, approximately present-day Galicia, northern Portugal, Asturias and León, and the later Kingdom of Gallaecia. The Roman cities included Auria (Ourense), the port of Cale (Porto), and the governing centers Lucus Augusti (Lugo), Bracara Augusta (Braga), and Asturica Augusta (Astorga), together with their administrative areas: Conventus Lucensis, Conventus Bracarensis, and Conventus Asturicensis, respectively.

Paulus Orosius (/ˈpɔːləs əˈroʊʒəs/; born c. 375/385 – c. 420 AD), 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 (now Braga, Portugal), 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. The date of his death is also unclear, although it appears to have not been earlier than 418, when he finished one of his books, or later than 423.

The Conventus Bracarensis (conventus iuridicus of Bracara Augusta), was a Roman administrative unit located in the northwest of the Iberian Peninsula, in Gallaecia. Its name derives from its capital Bracara Augusta (ancient Braga), a citadel established by the Romans, which became the convent's administrative center. Its southern limit was the river Douro, it marked the streak with the Roman province of Lusitania. In the north, its limits were the river Verdugo (located in the southern part of Galicia), and the river Sil, both marked the border with the Conventus lucensis (also in Gallaecia). Its eastern borders were marked by the river Navea, a tributary of the Sil, that limited with the Conventus asturicensis.

The convent was home to some native citadels and small villages inhabited by Gallaeci tribes, of Celtic origin, occupying all the territory and the Grovii, of possible Greek origin, living in the coast near river mouths.
