"The second angle of Spain," he writes, "points to the north-west, where Brigantia, a city of Galicia, is situated and rears its lofty lighthouse, of a structure with which few can be compared, looking towards Britain." The last words might also be taken to mean "for a view of Britain," and it was in this sense that they struck the imagination of the Irish schoolman. He thought of a tower so tall that Britain was actually visible from it. A few chapters further on he read that "Hibernia is an island situated between Britain and Spain," a notion of its position due to the fact that ships sailing by the old Atlantic trade route were accustomed to call at some Irish harbour on their voyages between Spain and Britain. If then Britain was visible from the lofty tower of Brigantia, and Ireland lay between Britain and Spain, Ireland must also be visible from the tower. Bregon or Breogan appears to have been a real name in Irish tradition. It resembled the name Brigantia. So we are told that Brigantia took its name from Bregon, the Gaelic chief, and that the tower there was built by him. This impression of Ireland lying within sight of Spain was confirmed by other passages of Orosius. "The ocean," he says, "has islands which they call Britain and Ireland, which are situated over against one side of Gaul and looking to Spain (_ad prospectum Hispaniae_)." And again speaking of Ireland: "The fore parts of this island, stretching towards the Cantabrian ocean (_i.e._, the Cantabrian part of the ocean, the Bay of Biscay) behold far away over a wide intervening space Brigantia, the city of Galicia, facing them towards the north-west, especially from that promontory where the mouth of the river Scena is, and where the Velabri and Luceni inhabit." The tower of Brigantia "looked towards" Ireland, and the south-western parts of Ireland "beheld" Brigantia. It is quite possible that Orosius himself used these expressions in their literal sense. At all events they were so interpreted by his Irish reader. The Irish legend tells us that the Sons of Mil, who was grandson of Bregon, having learned that a land was seen to the north-west from the tower of Bregon, set sail for that land and, after certain adventures, put into a haven called Inbhear Scéine. Where was Inbhear Scéine? Its locality has been the subject of some discussion. If you turn up the name in Dr. Hogan's Onomasticon, you will find that there are no data to enable you to decide which of the havens of south-western Ireland bore that name, and for a very good reason. The name Inbhear Scéine did not belong to Irish topography. It belonged to this story, and is a translation of the words of Orosius, _ostium Scenae_. There is no river of the name and no known record of the name as that of any river in Ireland: nor is there evidence that those who wrote and re-wrote the story of the Gaelic invasion in ancient times had any more definite notion of the locality of Inbhear Scéine than you or I have.
