Finally, after manyfruitless attempts, the solution of the problem was dis-covered at the Clunisian monastery of Vezelay, inBurgundy, the result being a groined roof or vault(Fig. 116), in which two diagonal ribs or cross spring-ers were framed in between semicircular arch ribs,thereby transferring the whole weight to the fourpoints at the angles where stood the piers. Thestrain on these piers being very great, it was deemedadvisable to strengthen them by external buttresses,which were connected with the nave piers by meansof arches called flying buttresses, while a weight inthe form of a pinnacle was placed over each buttressto counteract the pressure (Plates XXXIII and XXXIV).
