The fourteen-fold pilgrimage in Jerusalem was split into two distinct groupings some distance apart: of nine and five stations respectively.
The entombment and condemnation scenes form a pair.
The three falls with the cross and the nailing, death and deposition form natural triads.
The ‘Joseph’ scenes and those featuring female figures form natural quaternaries.
The stripping and entombment do not depict the cross.
A three-figured Resurrection would necessitate the omission of Jesus.
