Just like in the previous three bars, in the main text we present long accents as the same can be found in EE and FE, while the GC notation is ambiguous (GE has short accents). Moreover, bars 634-642 have the same shape in every source. In GC the marks are notated above the LH octaves. It seems little probable this is not consistent with the autograph. However, in GE the accents are notated below the octaves, which makes us cautious when it comes to evaluate the remaining sources, where the accents are placed between the staves. No accents in bars 639, 641-642 in EE might have resulted from negligence.
