Signy or Signe (Old Norse: Signý, sometimes known as German: Sieglinde) is the name of two heroines in two connected legends from Norse mythology which were very popular in medieval Scandinavia. Both appear in the Völsunga saga, which was adapted into other works such as Wagner's 'Ring' cycle, including its famous opera Die Walküre. Signy is also the name of two characters in several other sagas.
The first Signy is the daughter of King Völsung. She was married to the villainous Geatish king Siggeir who has her whole family treacherously murdered, except for her brother Sigmund. She saves her brother, has an incestuous affair with him and bears the son Sinfjötli. She burnt herself to death with her hated husband.
The second Signy is the daughter of King Siggeir's nephew Sigar. She fell in love with the Sea-King Hagbard, and promised him that she would not live if he died. They were discovered and Hagbard was sentenced to be hanged. Hagbard managed to signal this to Signy who set her house on fire and died in the flames whereupon Hagbard hanged himself in the gallows. See Hagbard and Signy.
A third Signy is the daughter of a witch named Grid in Illuga saga Gríðarfóstra. They are both delivered from a curse by a young man named Illugi.
A fourth Signy was Hroðgar's sister in Skjöldunga saga and Hrólfs saga kraka. She is unnamed in Beowulf.
