What kind of stone was used for the construction of the Panthenon's dome in Rome?

marble
sandstone
granite
pumice
The porous light stone was used in the concrete of the dome to reduce its weight. Sci­en­tists es­ti­mat­ed that, if normal weight concrete had been used through­out, the stresses in the arch would have been some 80% greater. The same tech­nique was for the ceilings of the Colos­se­um.
