So far as can be gathered from the most authentic sources, the palace of Emain Macha, or Emania, was erected by the over-king Cimboath, about five hundred years before the Incarnation. It continued to be the seat of the Ulster kings down to A.D. 331, when it was destroyed by the three Collas, chieftains of the race of the over-kings of Ireland from a hostile province, that made war on Ulster. The destruction of Emania is recorded by the Four Masters under the year 331, when Fergus, King of Ulster, was defeated and slain by the three Collas. Emania was burned, and the ancient dynasty that had so long ruled the province of Ulster was destroyed. Emania may be said to have been a desolation since then; for though we are told that one of the O'Neill's built a house within the ruins of the fort in 1387, no vestige of it now remains, and it is not probable that it was long in existence. None of the ancient palaces or great _duns_ of ancient Ireland shows such utter desolation, or bears evidence of having been so uprooted as does Emania. The great fosse by which it was once surrounded is entirely obliterated save on the west side, where it is nearly twenty feet in depth. Much as Tara has been obliterated, its monuments are more easily traced than are those of Emania. The county Meath seems to have been a grazing country almost from time immemorial. This saved Tara from being entirely uprooted; but the country round this ancient seat of the Ulster kings is essentially agricultural; it is mostly in the possession of small farmers owning from ten to twenty acres; consequently they have levelled most of the great circular embankments that formerly enclosed an area of nearly a dozen acres, and have filled up most of the deep fosse which, if we can judge by the small part of it that still remains, must have been, when Emania was in its glory, between twenty and thirty feet deep. So potatoes are growing and corn is waving over a large extent of the inside of the fortress, where vast wooden buildings once stood, and where mirth and revelry and clash of arms once resounded. Mons. Darbois de Jubainville, the eminent French archæologist and Celtic scholar, made an exhaustive examination of Emania some years ago. He found that the area within the original enclosure was four and a half hectares, or between eleven and twelve English acres in extent, and that the space enclosed was nearly circular. Like Tara, the buildings in Emania must have been almost entirely of wood. Some of them may, like many of the wooden houses in America, have been built on stone foundations, and there are some traces of stone-work still to be seen. There is a magnificent passage in the Féilere of Oengus the Culdee, written about A.D. 800, in which the greatness and glory of the Christian cities of Ireland are contrasted with the state of utter desolation into which the strongholds of the Pagan kings had fallen. Speaking of Emania he says--
