abstract The different elevation levels of the Pantheon floor within and the paving area outside the building are shown using five colour zones. These colours are a visualisation of all the elevation differences that are greater than 1cm. As one can see, the highest part of the floor lies in the middle of the rotunda, with a small depression in its centre. This depression is normally interpreted as being a system for collecting the rainwater coming down through the oculus in the centre of the cupola. The water then drains through small holes into the sewers underneath the depression. On every side of the rotunda the floor slopes down in all directions to the outside walls. The lowest point of the whole building is located at the threshold in the intermediate block between the portico and the rotunda. The maximum difference between the highest and lowest areas of the rotunda’s floor measures 15.70cm. The floor elevations inside the portico display a similar feature. The highest floor levels are at the front; the floor slants down almost consistently in the direction of the threshold. A maximum difference between the highest and lowest parts of the portico measures 2.25cm. These extreme differences of elevation may have been brought about by the immense weight of the rotunda’s outer walls, which must have had an impact on the surrounding floors, and would thus explain the deformations of the Pantheon’s interior and exterior pavement. For detailed views of the floor, cf. figures 40, 56a and 56b
