as Keating goes on to relate, for he was killed by turf-cutters. Sometimes the saints are found on opposite sides, as at the Battle of Cooldrevna where Columcille prayed against the High-king's arms, and Finian prayed for them; or as in the well-known case of the expulsion of poor old St. Mochuda[12] and his monks in 631 from the monastery at Rathain, where his piety and success had aroused the jealousy of the clerics of the Ui Neill, who ejected him by force, despite his malediction. It was then he returned to his own province and founded Lismore, which soon became famous.[13] Led away by our admiration of the magnificent outburst of learning and the innumerable examples of undoubted devotion displayed by Irishmen from the sixth to the ninth century, we are very liable to overlook the actual state of society, and to read into a still primitive social constitution the thoughts and ideas of later ages, forgetting the real spirit of those early times. We must remember that St. Patrick had made no change in the social constitution of the people, and that the new religion in no way affected their external institutions, and as a natural consequence even saints and clerics took the side of their own kings and people, and fought in battle with as much gusto as any of the clansmen. Women fought side by side with men, and were only exempted from military service in 590, through the influence of Columcille at the synod of Druimceat--of which synod more hereafter, and Adamnan had to get the law renewed over a hundred years later, for it had become inoperative. The monks were of course as liable as any other of the tribesmen to perform military duty to their lords, and were only exempted[14] from it in the year 804. The clergy fought with Cormac mac Culenain as late as 908 at the battle where he fell, and a great number of them were killed.[15] The clergy often quarrelled among themselves also. In 673 the monks of Clonmacnois and Durrow fought one another, and the men of Clonmacnois slew two hundred of their opponents. In 816 four hundred men were slain in a fight between rival monasteries. The clan system, in fact, applied down to the eighth or ninth century almost as much to the clergy as to the laity, and with the abandonment of Tara and the weakening of the High-kingship, the only power which bid fair to override feud and faction was got rid of, and every man drank for himself the intoxicating draught of irresponsibility, and each princeling became a Cæsar in his own community. The saints with their long-accredited exercises of semi-miraculous powers, formed an admirable ingredient wherewith to spice a historic romance, such as the soul of the Irish story-tellers loved, and they were not slow to avail themselves of it.
