Gleanings from Woronińce, S. 249

Liszt had first met the Princess when he played in Kiev on 14 February of that year. She was recently separated from her husband, and she invited Liszt to spend some time on her estate in Podolia. He stayed for 10 days, then left for a concert tour, promising to return in the autumn. He came back around 18 September, and stayed till early January 1848. It was during these three months that Liszt's and Sayn-Wittgenstein's relationship developed to the stage that she planned to petition the Tsar for divorce, and marry Liszt. During this time, Liszt also completed much of his Harmonies poétiques et religieuses.
