I think it's about a girl who has many suitors who are trying to win her favor. The song is using some strong imagery to show the lust of the suitors. For example this situation is compared with the contest that was held in ancient Sparta in front of the altar of Diania. Apparently the hero of this song believed that he was the one that she loved. The swans is probably a symbolism of purity and their releasing is the decision of our hero to search for a purer heart.
