91. PARISH CHURCH OF TILLIERES, NEAR DREUX : CHOIR-VAULTS. 



RIB-AND-SLAB CEILINGS. -The multiplication of 

 ribs tended to leave intervals so small that a single 

 stone would fill them, whence there arose in Nor- 

 mandy a type of rib-and-slab ceilings, which reached 

 its richest development in the chevet chapels of St 

 Pierre, Caen, and at La Ferte Bernard. The rib 

 system of a more or less complicated vault was used 

 in skeleton (with the spandrils filled either with slabs 

 or with tracery), upon which another and nearly 

 horizontal framework of ribs reposes, whose spaces 

 are each filled in with a slab. Every part is enriched 

 with scrollwork and carving, and pendents hang like 

 stalactites from each intersection. Figs. 91 and 92 

 show a comparatively simple example from the chancel at Tillieres.
