Out of the three forms in which the slur beginning in bar 156 appears in the sources, only the version of A and GE2 is authentic. The whole-bar slur of GE1 (→FE) is a result of the manner of adjusting slurs to metric structures, in this case bars (the slurs in adjacent bars were distorted in a similar way). In EE the moment of the slur's beginning was moved most probably on the basis of comparison with analogous bars.
