Breogán (also spelt Breoghan, Bregon or Breachdan) is a character in the Lebor Gabála Érenn, a medieval Christian history of Ireland and the Irish (or Gaels). He is supposedly the son of Brath, and is described as an ancestor of the Gaels. The Lebor Gabála purports to be an account of how the Gaels descend from Adam through the sons of Noah and how they came to Ireland. It tells us that they spent 440 years wandering the Earth and underwent a series of trials and tribulations. Eventually, they sail to Iberia and conquer it. There, one of their leaders, Breogán, founds a city called Brigantia and builds a great tower. From the top of the tower, his son Íth glimpses Ireland. The Gaels, including some of Breogán's sons, sail to Ireland from Brigantia and agree to divide it between them and the Tuatha Dé Danann, the Irish pagan gods, who take the Otherworld. Brigantia likely refers to A Coruña in present-day Galicia and Breogán's tower is likely based on the Tower of Hercules (which was built at A Coruña by the Romans) or the Tower of Babel. The idea that the Irish Gaels came from Hispania may be based on the similarity of the names Iberia and Hibernia and the names Galicia and Gael. Medieval pseudo-historians made similar claims about other nations based on their names. A similar story about a monk who voyaged to a marvelous island he saw from the top of the tower of Brigantia was written in the first years of the eleventh century in Galicia. The story, preserved in two 14th-century manuscripts, is known as Trezenzonii de Solistitionis Insula Magna ("Trezenzonius' Great Island of the Solstice"). His son was Bile, who was in turn the father of Milesius (also called Míl Espáine, soldier of Hispania or Spain), said to be the ancestor of the Irish people. Although this is generally regarded as myth, the conquering of Ireland by people coming from the Iberian peninsula in prehistoric times fits in with a genetic study conducted in 2006 at Oxford University, which concluded that the majority of people in the British Isles are actually descended from neolithic farmers coming from the coastal north regions of Spain. The Lebor Gabála was a hugely popular and influential work. Galicia itself is sometimes described poetically as the "Home" or "Nation" of Breogán (in Galician, the fogar or nazón de
