The heroism of patient endurance was a bravery but little understood at that period.

If the heathen Viking was brave when he plundered and burned monastic shrines--when he massacred the defenceless with wanton cruelty--when he flung little children on the points of spears, and gloated over their dying agonies; perhaps we may also admit those who endured such torments, either in their own persons, or in the persons of those who were dear to them, and yet returned again and again to restore the shrine so rudely destroyed, have also their claim to be termed brave, and may demand some commendation for that virtue from posterity.
As plunder was the sole object of these barbarians, they naturally sought it first where it could be obtained most easily and surely.

The islands on the Irish coast were studded with monasteries.

Their position was chosen as one which seemed peculiarly suitable for a life of retreat from worldly turmoil, and contemplation of heavenly things.

They were richly endowed, for ancient piety deemed it could never give enough to God.
