This may at first sight seem very improbable. We must not, however, forget the celebrated lines of Claudian:[218] "Maduerunt Saxone fuso Orcades: incaluit Pictorum sanguine Thule: Scotorum cumulos flevit glacialis Ierne." This, it may be said, was written three or even four centuries after the events of which we are now speaking; but it was also written five centuries before the Northmen are generally supposed to have occupied the Orkneys or to have interfered in the affairs of Ireland, and does point to an earlier state of affairs, though how much anterior to the poet's time there is nothing to show. It has been frequently proposed to identify the Dananns with the Danes, from the similarity of their names. Till I visited Sligo, I confess I always looked on this as one of those random guesses from identity of mere sound which are generally very deceptive in investigations of this sort. The monuments, however, on the battle-field correspond so nearly to those figured by Madsen in his 'Antiquités préhistoriques du Danemark,'[219] and their disposition is so similar to that of the Braavalla feld[220] and other battle-fields in Scandinavia, that it will now require very strong evidence to the contrary to disprove an obvious and intimate connection between them. In concluding his account of the battle, Mr. O'Curry adds: "Cormac Mac Cullinan, in his celebrated Glossary, quotes this tract in illustration of the word _Nes_; so that so early as the ninth century it was looked upon by him as a very ancient historic composition of authority."[221] If this is so, there seems no good reason for doubting his having spoken of events and things perfectly within his competence, and so we may consider the account above given as historical till at least some good cause is shown to the contrary. * * * * *
