The story of Lohengrin as we know it is based on two principal motives common enough in folklore: the metamorphosis of human beings into swans, and the curious wife whose question brings disaster.
Lohengrin's guide (the swan) was originally the little brother who, in one version of "the Seven Swans," was compelled through the destruction of his golden chain to remain in swan form and attached himself to the fortunes of one of his brothers.
But in French story Helyas is not the son of Parzival, but of the king and queen of Lillefort, and the story of his birth, of himself, his five brothers and one sister is, with variations, that of "the seven swans" persecuted by the wicked grandmother, which figures in the pages of Grimm and Hans Andersen.
In 1697 the Dutch captain Vlamingh landed on the west coast of Australia, then called New Holland, in 31° 43' S., and named the Swan river from the black swans he discovered there.
In the eastern portion of the Coastal Plain Region are the cotton rat, rice-field rat, marsh rabbit, big-eared bat, brown pelican, swallow-tailed kite, black vulture and some rattlesnakes and cotton-mouth moccasin snakes, all of which are common farther south; and there are some turtles and terrapins, and many geese, swans, ducks, and other water-fowl.
