Not yet content with blood and flame, he crossed to Wales and ravaged there, then sailed to France to do there what mischief he could. After a while he turned back, and sighted the Scilly Isles, and then ran his fleet into the harbour of S. Mary's, the largest of the isles. Here Olaf heard tell of a hermit who lived in a cell among the granite crags, and who was believed to have the gift of prophecy. "I will test his powers," said Olaf. Then he dressed up one of his men in his armour, gave him his spear and red-cross shield, and sent him to consult the old man. But no sooner did the hermit see the fellow than he said, "Thou art not King Olaf, thou art a servant. Beware that thou be not false to him, that is my rede to thee." No more would he say. Then the party returned to the ship and told Olaf. He was highly pleased, and went ashore in a boat with a small following, that he might consult the anchorite as to the prospect of his being able to recover the kingdom of his ancestors. The hermit was undoubtedly a Cornish Briton, and Olaf was obliged to hold communication with him through an interpreter from Ireland or Wales. The old man said to him, "There is a great future in store for thee, Olaf. Thou wilt have to pass through much conflict, but in the end wilt reign in thine own land; and when that comes to pass remember to advance the faith, and to use every opportunity to turn men from their idols." Now the interpreter knew that there was discontent simmering among the followers of the prince. They wanted to return to their homes with the plunder they had acquired, but Olaf set his face against this. The interpreter, knowing that the men were mutinous, said a few words in Welsh or Irish to the hermit. He was afraid of himself giving warning to Olaf, lest the mutineers should wreak their resentment on him. So the anchorite told the king that there were those amongst his followers who plotted, and purposed seizing the opportunity of his being on land to execute their design of revolt. Olaf precipitately returned to his ships, and found that the mutineers were making off with some of the ships. He hurried on board, gave chase, and a fight ensued. Finally the mutiny was quelled, but not without Olaf being wounded. His vessel then put into Tresco harbour, where were monks to whom Athelstan had granted land in 936. He was carried into the monastery, carefully tended, and was induced to receive baptism. Hitherto, though convinced that Christianity was the true religion, Olaf had never formally been enrolled in the Church. Unhappily, Olaf could not speak Cornish, and the abbot was ignorant of the Norse tongue, so that all communication had to go on through the interpreter, and Olaf did not receive much religious instruction. Nevertheless, as far as his lights went, he was sincere. Then he returned to Norway to proclaim his right to the throne.
