At the end of his second year in Leipzig, J.S. Bach composed nine sacred cantatas to texts by Leipzig poet Mariana von Ziegler (1695-1760). Despite the fact that these cantatas are Bach’s only compositions to texts by a female poet, the works have been largely ignored in the Bach literature. Dr Mark Peters presents the first comprehensive account of this repertory, providing a significant new perspective on both Ziegler as poet and cantata librettist and Bach as cantata composer.
