It took Wagner almost a decade to gestate the opera Lohengrin, his third masterpiece after The Flying Dutchman and Tannhäuser. His first encounter with the medieval German myth had been in 1841 but it took him five years to figure out how to bring it to the stage. Then, two years later, in 1848, he finished composing the score.
Lohengrin
The story takes place in the tenth century and tells the vicissitudes of Elsa, unjustly accused of making her brother – then a child but a future duke – disappear. An enigmatic knight will arrive to protect her and eventually take her in marriage, as long as he never asks for her name. The knight, naturally, is Lohengrin, who like all knights of the Holy Grail, must remain anonymous while performing his good deeds. Lohengrin arrives in a boat, towed by a swan. In that same boat he will leave when Elsa, curious, asks for his name, thus ending the enchantment.
Before leaving Dresden, he asked his friend Franz Liszt (whose daughter Cosima would later marry Richard, 24 years older) to ensure that Lohengrin was performed in his absence. So Liszt did, conducting the premiere of the work in Weimar, in August 1850.
