chief to restore the animals which had been stolen from _him_. “Thou mayst have them,” replied Olaf, “if, without impeding our march, thou canst distinguish them from such a multitude.” The man had a dog, which singled out the animals, one by one, to the great amazement of the chief. “Wilt thou part with this dog?” demanded Olaf. “Readily!” was the answer; and Olaf, not satisfied with restoring the man’s cattle, made him some valuable presents.[208] [Sidenote: 967 to 993.] In all his voyages, Olaf never despaired of being one day able to procure the rights of his birth in Norway, and his eyes were frequently turned to that country. Nor was he without anxiety as to the fate of his mother, of whom he had heard nothing since the day on which, while yet an infant, he had been separated from her. Her adventures may, for a moment, occupy the reader’s attention. After remaining a slave for some time, she was seen in Pomerania by a Norwegian pirate of noble birth: at first he did not recognise her; where health and cheerfulness and beauty had once been, he observed paleness and melancholy; but there was, alike in her appearance and manner, something that inspired him with respect. A closer examination convinced him that he saw Astridda, the queen of Trygve, before him; he entered into conversation with her, and learned that she was now on sale. She besought him to ransom her, and return her to her friends; and he promised to do so on one condition,—that she would become his bride. Her situation was not one that admitted of either scruple or hesitation; she became his wife, and the mother of several children. Year after year rolled away, and the mother heard not of the son, or the son of the mother. The fame of his exploits, indeed, had reached Norway; but he had assumed another name,—that of Olo, a native of Gardarik, and by it he was known to all the princes of his time, from the imperial Otho to the humblest piratical chief. But Hako, the usurper of Norway, knew the truth; and as his favour with the people, from his new vices, was now departing[209], he began to look with much anxiety towards Ireland, where Olaf had for some time been. To remove this aspiring rival was necessary to his safety; and he immediately devised the means of carrying his design into execution.[210] [Sidenote: 995 to 996.]
