its always weird to think those massive stone vaults above cathedrals are actually just a hollow shell

Source of filling part: "Once vaulted construction was adopted outside of Italy, bricks were often substituted for the radially laid caementa of unhewn stone. A brick vault usually consisted of a brick shell forming the intrados with a fill of mortared rubble above it (Fig. 17A).1 T" Chapter 3.

Excellent video! I am curious about how the thrust of the flyers was handled during construction of the vaulting. I would think that they would tend to push in the clerestory wall until the interior vaults were in place and their thrust "activated", particularly in buildings like Notre Dame, Paris, where the walls are so comparatively thin. Was the centering for the flyers kept in place until the vaulting was completed, or was there some other mechanism used?

Hi Chris, good to hear from you again. The clerestory wall was erected first. Then the flyers were erected simultaneously to the wood and lead roof (aka forêt). The horizontal beams of the roof counteracted the inward thrust of the flyers pressing against the clerestory. From the wood roof, wood platforms and construction work on the vaults could be suspended. This had the added benefit of sheltering the vaults from the elements during their construction and saving on the amount of temporary scaffolding required for the vaults. The rebuilding of Notre-Dame, of course, reverses this process because the vaults are already in place, and most rebuilding will focus on the roof.

Thank you Myles. It occurred to me after I posed my question that the roof truss, particularly the bottom chord, may have provided enough counter-thrust to keep the flyers stable while the vaulting was constructed. Still, it must have been a tricky job, and Notre Dame's great height must have made it even trickier with the increased wind loads. I always enjoy your posts, though it's probably obvious that I have a special interest in medieval architecture. So much of what was presented to me as "established fact" fifty years ago is now being questioned, and many conclusions are being overturned. It's very exciting! Sorry if this is a repeat post. I am not seeing my initial response, so I decided to give it another try.

So many people died building these just to satisfy human vanity.

Was it human vanity ? Or creating lasting works of culture? 30 people died building the Brooklyn Bridge, I think 3 died building the Empire State Building, should these lasting achievements of human architecture never have been attempted?
