I want to know the answer to the following question:
At which cathedral is the pointed arch used to match the heights of transverse and diagonal vaults?
All the background I'm provided with is that "Contrary to the diffusionist theory, it appears that there was simultaneously a structural evolution towards the pointed arch, for the purpose of vaulting spaces of irregular plan, or to bring transverse vaults to the same height as diagonal vaults.". Is that enough to answer the question?
Answer: no
