The Mass No. 13 in B flat major, Hob. 22/13, was composed by Joseph Haydn in 1801. It is known as the Schöpfungsmesse or Creation Mass because for the words "Qui tollis peccata mundi" in the Gloria, Haydn recycled music from the Adam and Eve's final duet in The Creation, a fact which scandalized Empress Maria Theresa so much that she ordered Haydn to recompose that passage for her own copy of the work.
