Dun Conor, an oval fort on the middle island, is much larger than Dun Ængus, of which we have just been speaking, the axis major of Dun Conor measuring 227 feet. It also stands on a high cliff, and its dry and mortarless walls are built also on the coat of the onion principle. Inisheer, the eastern island, contains a circular Dun called Creggan-keel. Furmena Castle, also on this island, was, in later times, the stronghold of the O'Briens--lords of the islands of Aran--and upon these islands are many more fortresses. There is, on the north side of Inishmore, Dun Onaght, a circular Firbolgic fort, measuring 92 feet across; and on the south-west side, _Dubh Cahn_, "the black fort," a Dun or fortress of very rude masonry, of enormous thickness, and overlooking the cliffs. [Sidenote: ST. ENDA.] The Christian remains of the islands are many, and many are the names of the saints still remembered who congregated here in the early days of Irish Christianity. Amongst those remarkable heroes of the Cross, none appears to have been greater than St. Enda, who has left his name everywhere in the islands. To him, indeed, is due much of the success that followed the footsteps of those missionaries who won, in the course of centuries, for Aran the appellation of "Aran of the Saints." Enda was the only son of Conel, King of Oriel, whose territories included the modern counties of Louth, Armagh, and Fermanagh. This Enda had, however, several sisters, the elder being the wife of the King of Cashel, whose death is chronicled in the annals of the Four Masters as of the year 489; the younger was Fancha, the abbess of an abbey, or nunnery, wherein were educated ladies of the court, amongst whom was one remarkable for her great mental and personal attractions. Enda loved her, and hoped that she would one day share with him the glories, such as they were, of the throne of his fathers. His love for his affianced bride amounted to an idolatry, but his idolatry must end, and his idol must die an early death. The abbess brought him weeping into the chamber where the corpse of his loved one was laid. Fancha then reminded him of how favour is deceitful and how beauty is vain, and how the day, dim and remote, would still come when he would be as his affianced bride now was. "Love not the world, nor the things that are in the world!" exclaimed the abbess with a vehemence that her earnestness inspired. That world was then abjured, and straightway he entered a religious order, that of the Regular Canons of St. Augustine, and after years of study and probation, was ordained priest in Rome. He thence returned to the kingdom of Oriel in Ireland, where he built several churches. Having visited his sister and her husband the King of Cashel, the latter was, after much hesitation, persuaded to confer upon God and upon Enda the islands of Aran. Possession of a place so retired and so suited to study and contemplation being thus obtained, Enda introduced there a multitude of
