Note 347 — Chapter VII · NORMANDY.

This arrangement is known by the name of hexapartite, or sexapartite, because the compartment of the vault having been divided into four by the great diagonal arches crossing one another in the centre (which was the quadripartite arrangement), two of the four quarters were again divided by the arch thrown across from one intermediate pillar to the other, thus making six divisions in all, though no longer all of equal dimensions, as in the quadripartite method. Both these arrangements are shown in plan on Woodcut No. 612.
