Primato romano delle volte. Il Tempio di Diana a Baia
We have chosen the Temple of Diana because of its unique ovoid shape. Opus caementicium allowed the Romans to build domes and vaults of great amplitude, thanks to an expert use of rubble, mortar, laying techniques and, above all, geometrical parameters, especially as regards the appropriate outline for the span and thickness to ensure stability. The intrados is contained in a hemisphere but it is not one itself. Finally, a set of measurements can be taken across the entire surface to tell us about the geometry and structural behav-iour.
