Sadko in the Underwater Kingdom, a painting by Ilya Repin depicting Sadko, a Russian folk hero of a bylina of the same name, though this painting depicts only one specific version of that tale. In this version, the Sea King wants Sadko to marry one of the many underwater beauties (daughters). However, if he chooses one of them he will remain under the sea forever. Instead he is supposed to pick an unremarkable servant girl -- pictured in the upper left hand side -- who will magically help him return to Novgorod and his human wife there. The story inspired both an opera and musical tableau.Artist: Ilya Repin
