The Great Silkie of Sule Skerry

"The Great Silkie of Sule Skerry" or "The Grey Selkie of Sule Skerry" is a traditional folk song from Orkney and Shetland. A woman has her child taken away by its father, the great selkie of Sule Skerry which can transform from a seal into a human. The woman is fated to marry a gunner who will harpoon the selkie and their son.

"The Great Silkie of Sule Skerry" is a short version from Shetland published in the 1850s and later listed as Child ballad number 113. "The Grey Selkie of Sule Skerry" is the title of the Orcadian texts, about twice in length. There is also a greatly embellished and expanded version of the ballad called "The Lady Odivere".
