Soon after FRIDLEIF was admonished by his people to think about marrying, that he might prolong his line; but he maintained that the unmarried life was best, quoting his father Frode, on whom his wife's wantonness had brought great dishonour. At last, yielding to the persistent entreaties of all, he proceeded to send ambassadors to ask for the daughter of Amund, King of Norway. One of these, named Frok, was swallowed by the waves in mid-voyage, and showed a strange portent at his death. For when the closing flood of billows encompassed him, blood arose in the midst of the eddy, and the whole face of the sea was steeped with an alien redness, so that the ocean, which a moment before was foaming and white with tempest, was presently swollen with crimson waves, and was seen to wear a colour foreign to its nature.

The firth into which both fleets had mustered is called Frokasund. Here Fridleif left the camp at night to reconnoitre; and, hearing an unusual kind of sound close to him as of brass being beaten, he stood still and looked up, and heard the following song of three swans, who were crying above him:
