Vikings in Iberia
The first incursion of the Vikings in Iberia has been characterised as 'probably the most significant episode of the whole period of Viking activity in the South'. It is mentioned in "Annales Bertiniani", and dated August 844, when a group from a plundering expedition entered the Garonne and reached Galicia. Despite storm damage, some proceeded to South-West Spain. This account is consistent with several later, but independent sources in Latin and Arabic. In particular, the late ninth- or early tenth-century "Chronicle of Alfonso III" adds that after plundering a number of coastal villages they were ultimately repulsed in the vicinity of "Farum Brecantium" (i.e. the Tower of Hercules). Ramiro I of Asturias gathered troops in Galicia and Asturia for the counter-attack. After the Asturian victory, the Vikings continued their voyage in direction of Lisbon. While some authors consider that the reliability of this chronicle is open to doubt, others consider that other local chronicles confirm the arrival of the Norsemen.
Vikings (2013 TV series)
The series is inspired by the tales of the Norsemen of early medieval Scandinavia. It broadly follows the exploits of the legendary Viking chieftain Ragnar Lothbrok and his crew, family and descendants, as notably laid down in the 13th-century sagas "Ragnars saga Loðbrókar" and "Ragnarssona þáttr", as well as in Saxo Grammaticus's 12th-century work "Gesta Danorum". Norse legendary sagas were partially fictional tales based in the Norse oral tradition, written down about 200 to 400 years after the events they describe. Further inspiration is taken from historical sources of the period, such as records of the Viking raid on Lindisfarne depicted in the second episode, or Ahmad ibn Fadlan's 10th-century account of the Varangians. The series begins at the start of the Viking Age, marked by the Lindisfarne raid in 793.
