The prince lived with his fighting men in his great war galley, except during the winter, when they encamped on one or other of the islands of Loch Ewe. Often would Olaf repair to the hermitage of Isle Maree, and receive from the saint kindly advice and priestly absolution.
It was natural that one so impulsive should early fall under the influence of the tender passion. We need not try to imagine the story of Olaf's love; it was no common attachment; the flame burned in his breast with an intensity becoming his fiery spirit.
But a difficulty arose. He was unwilling, at least at first, to ask his bride to exchange the comparative quietude of her father's home for the restless life of a ship of war. In dire perplexity he sought the advice of his friend the saint of Isle Maree. The wise old man proposed that another and a larger dwelling should be erected in the form of a tower to the west of the enclosure in the centre of which stood his own humble cell. To this tower Olaf might bring his bride and there they might take up their abode, within easy reach of the prince's galley on Loch Ewe.
To hasten on. The prince eagerly adopted this plan, and in a short time the tower was built, and Olaf brought his bonny bride to the island. Here they were married by the aged hermit, amid the rejoicings of their followers. The princess and her maidens were delighted with the romantic and secure retreat. Olaf's attendants pitched their tents around, and the leafy grove grew gay with joyful laughter and with genial song.
For a while all went smoothly. The life of the young lovers was a continual delight; their passion for one another only increased as months rolled on. In vain his comrades sent message after message entreating the presence of the prince on board his ship. He could not tear himself away from his darling, and she in turn was more than unwilling that he should leave her. At length there came word that a long-planned expedition, in which other leaders were to take part, was ready to start, and Olaf was expected to assume the command. He dared no longer remain in retirement. With aching heart he told the princess of his approaching departure. Her tears were unavailing; on the morrow he must leave. Meanwhile strange forebodings of evil filled the minds of both. What if he should be slain in battle! What if some unknown danger should cause her death in his absence! A scheme was concocted for shortening the final moments of suspense. It was agreed that when the prince should return, a white flag would be displayed from his barge on Loch Maree if all were well; if otherwise, a black flag would be shewn. The maidens prepared these flags, and the prince took them with him. The princess was to leave the island in her barge whenever her lord's boat should come in sight, and she in like manner was to display a white or black flag to denote her safety or the reverse.
The morning came, and they parted. The prince arrived at Poolewe, was received by his men with wild enthusiasm, and set sail at once. It is not necessary that we should follow him through the perilous campaign. Enough that all ended well, and the victorious prince returned safely to Poolewe. In hot haste, and half crazy with excitement, he sought his boat on Loch Maree, raised with his own hand the snow-white banner of success, and mustered the faithful attendants who were to row him to Isle Maree.
During his absence the princess had passed through several phases of anxiety. At first despair took possession of her heart, and it was long ere the good old saint and her own maidens were able to soothe her with words of hope. As she became calmer, a new misgiving occurred to her. Did Olaf prefer the excitement of warfare to the peaceful society of his bride? Had she lost the devotion of his heart? Did he really love her? Then horrible jealousy became her absorbing feeling. Was the faithless prince to treat her as an insignificant plaything, to be caressed one day and deserted the next? It was all in vain that her companions strove to check this new folly; she declared continually that her husband had never truly loved her. Under the influence of this crushing doubt, she devised a scheme whereby she resolved to test the reality of his vaunted affection, if indeed he should ever return.
