From this they rowed away; and after a long time they came at midnight to an island wherein was a community of Ailbe of Emly.[CLXVIII.] On the beach they found two spring wells; one foul, the other bright and clear. The gilla wished to drink of the clear well; but the elder (the bishop) told him it was better to ask leave, if there was anyone living on the island. Then they saw a great light; and coming closer, they found the twelve men of the community at their prayers; and now they perceived that the bright light they saw came from the radiant faces of the twelve; so that these holy men needed no other light. One of them, an old man, comes towards the voyagers; and he bids them welcome and asks news of them. They tell him all their adventures, and ask his leave to drink from the well; whereupon he said to them:--"Ye may fill your pitchers from the clear well, if your elder (_i.e._ the bishop) gives you leave." "Who are ye?" asks the gilla. "A community of Ailbe of Emly," says he: "and we are the crew of one of Ailbe's curraghs. God has permitted that we live here till the Day of Judgment, praying for everyone who is drowned at sea. And now leave this land before morning," he added, "for your resurrection is not to be here. And if ye have not left by the dawn, so much the worse for yourselves; for if once ye get a view of this island in the light of day, bitter will be your anguish of mind for leaving it (on account of its surpassing loveliness). So it is better for you to go away during the night." And they did exactly all he told them to do. "Shall we take away some of the pebbles of the strand?" said they (talking among themselves). "It is better to ask leave," answered the cleric. So the gilla asked leave of the same old man. "Yes, if you have the permission (of your bishop)," answered he. "Nevertheless," he added, "those who take them will be sorry; and those who do not take them will be sorry also." They pick up pebbles, some bringing away one, some two, some three. (After which they row away in the dark night from the island.) In the morning they drank some of the spring water of the island from their pitchers; which threw them into a deep sleep from that time till next day. On wakening up, they examined their pebbles in the light; and some were found to be crystal, some silver, and some gold. Then those who brought some away were in sorrow that they had not brought more; and much greater was the sorrow of those who had brought away none. So the words of the old man came true. XVIII.
