In the 19th century aprox. 100 texts with a reference to the Danish Medieval Ballads are published in Denmark. The intermediality and intertextuality between the old ballads and the 19th century re-makes are seldom submitted to further investigation. My research shows that especially the ballads of the Supernatural and the Historical Ballads give themes to the more or less romantic re-makes. In this paper I look upon a play written by Henrik Hertz: Svend Dyrings Huus [The House of Svend Dyring] from 1837. His inspiration comes from two ballads of the supernatural, DgF 89, Moderen under Mulde [The Mother in the Ground (???)/ The Buried Mother] and DgF 76, Ridder Stigs Bryllup [The Marriage of Sir Stig]. The writer, poet and critic, Johan Ludvig Heiberg, wrote a dissertation about the play. In here he looks upon the nationalistic and aestetic aspects of the play and discusses the genre. His work is discussed as well.
