In Gottfried’s Tristan, the Queen of Ireland, wife of King Gurmun of Ireland, and mother to Tristan’s lover Isolde.
She cleverly convinced her husband to make peace with Cornwall and to give their daughter to King Mark. She concocted the fateful potion, intended for Mark and Isolde, which bound Tristan and Isolde in love.
In most other versions, her character is unnamed.
