Bach’s lost St Mark Passion was first performed in Leipzig on Good Friday 1731 and a second time in 1744 in a revised version. Though Bach's music is lost, the libretto by Picander is still extant, and from this, the work can to some degree be reconstructed. Unlike Bach's earlier existing passions (St John Passion and St Matthew Passion), the Markus-Passion is probably a parody – it recycles previous works. Which of his own works Bach may have taken for his St Mark Passion led to numerous speculations. Differently from further reconstructions the Frankfurt musicologist Prof. Karl Böhmer used the revised Picander text from 1744 which schedules one Aria and a chorale more than the 1731 version. Other parts have been revised and complemented.
The recitative parts and the choruses for the crowd are not anymore reconstructable and Felix Koch with his Gutenberg Chamber Choir and the Neumeyer Consort foregoes wild speculations or new compositions. These parts are spoken by Wolfgang Vater after the revised Picander version from 1744.
