 The seventeen-year-old girl first met Goethe in 1821 at Marienbad and again at Carlsbad in 1822 and 1823.The poet, then 72, was so carried away with her wit and beauty that he thought for a time of marrying her and urged Grand Duke Karl August of Saxe-Weimar-Eisenach to ask for her hand in his name.Rejected, he left for Thuringia and addressed to her the poems which he afterward called "Trilogie der Leidenschaft".
