The sons of Hugh III., Dermid and Blathmac, zealous and pious Christian princes, survived the field of Moira and other days of danger, and finally attained the supreme power—A.D. 656. Like the two kings of Sparta they reigned jointly, dividing between them the labours and cares of State. In their reign, that terrible scourge, called in Irish, "the yellow plague," after ravaging great part of Britain, broke out with undiminished virulence in Erin (A.D. 664). To heighten the awful sense of inevitable doom, an eclipse of the sun occurred concurrently with the appearance of the pestilence on the first Sunday in May. It was the season when the ancient sun-god had been accustomed to receive his annual oblations, and we can well believe that those whose hearts still trembled at the name of Bel, must have connected the eclipse and the plague with the revolution in the national worship, and the overthrow of the ancient gods on that "plain of prostration," where they had so long received the homage of an entire people. Among the victims of this fearful visitation—which, like the modern cholera, swept through all ranks and classes of society, and returned in the same track for several successive seasons—were very many of those venerated men, the third and fourth generation of the Abbots and Bishops. The Munster King, and many of the chieftain class shared the common lot. Lastly, the royal brothers fell themselves victims to the epidemic, which so sadly signalizes their reign. The only conflicts that occurred on Irish soil with a Pictish or an Anglo-Saxon force—if we except those who formed a contingent of Congal's army at Moira—occurred in the time of the hospitable Finnacta. The Pictish force, with their leaders, were totally defeated at Rathmore, in Antrim (A.D. 680), but the Anglo-Saxon expedition (A.D. 684) seems not to have been either expected or guarded against. As leading to the mention of other interesting events, we must set this inroad clearly before the reader.
