Between the years 1870 and 1884 the late Mr J. F. Campbell of Islay was repeatedly attracted by a series of legends current in the Highlands and Isles, which made special appeal to him as a storyologist. After reading a dozen versions of the stories, he found that no single title fitted so well as that of the Dragon Myth. "It treats of water, egg, mermaid, sea-dragon, tree, beasts, birds, fish, metals, weapons, and men mysteriously produced from sea-gifts. All versions agree in these respects; they are all water myths, and 
relate to the slaying of water monsters."
