In the south of France(where the Byzantine influence had been strongly 23 GOTHIC AECHITECTURK felt, through • the Mediterranean commerce), thepointed tunnel-vault (tig. 5) had been long in use,and had superseded the semicircular tunnel-vaultprobably as early as the 9th or 10th century. Thisform of arch was thus probably suggested to thearchitects of the north of France, who at oncesaw how well it would overcome the difficulty ofthe }-ielding of the haunches in the semicirculararch. They were thus led to the adoption of thepointed form for their ti-ansverse arches as a struc-tural expedient, and still retained the semicircidarform in the groins. The next question whichengaged attention, and the solution of which led tothe further use of the pointed arch, was the vaidt-ing of oblong spaces. This had been tried withsemicircidar arches, but it was found that in thisway the vaidt would require to be very muchdomed—the diameter of the arches (c, c, fig.
