three new additions (Movements 10 and 15), the first violin part is missing and has been reconstructed. Of the new additions (Movements 10, 15, and 30), Alfred Dürr noted that the bass line of Movement 10 mirrored exactly the bass line of the sacred song from Georg Christian Schemelli's Musicalisches Gesang-Buch, So gehst du nun, mein Jesus, hin BWV 500 (it is included in the BWV catalog as BWV 500a). Movement 15 was used as a replacement of Movement 14 of BC D 5a, and is cataloged as BWV 1084 (no BC number yet) and is also marked alla breve as is its predecessor, but instead of half notes as the main beat, the quarter note gets the main beat. Movement 30 was used to replace Movement 29 of BC D 5a, and is cataloged as BWV deest serie II: 04 (similar case as far as notation to Movement 15). Leipzig 1747–1748 (BNB I/K/2) Bach again revived this pastiche on either 31 April 1747 (at the St. Nicholas Church, Leipzig) or 12 April 1748 (at the St. Thomas Church, Leipzig). Of all the pastiches, this one was the most complex and involved. In many ways, it was more a true pastiche than the previous two were. In addition to his own music (two movements), Bach incorporated seven arias from George Frideric Handel's Brockes Passion HWV 48 into the original. This work (BWV deest – Serie II: 005; BC D 5; BNB I/K/2) has come down only in two partial manuscripts. One is a complete harpsichord part of 10 pages dating from between 1743 and 1748 housed at the Staatsbibliothek zu Berlin under Catalogue number D B N. Mus. ms. 468. This part is written in the hands of Johann Christoph Friedrich Bach (notes), Johann Sebastian Bach (figures), and Wilhelm Rust (title page). Its title page reads "Marcus-Passion / angeblich von R: Keiser" and underneath this "NB enthält 6 Arien aus der Brockes'schen / Passion von Händel". After Bach's death, it came into possession of an unknown individual, from whom it entered into possession of Wilhelm Rust, whose heir Maria Rust next took possession of it. It then entered into the possession of an A. Martin in Weimar, from whence it entered into (in succession) the possessions of an A. Thiele and then B. Thiele (also in Weimar), from whence it entered into the possession of the Antiquarian Bookshop of Joseph
