THE remains of the ornamentation upon the exterior surface of the building testify to the beautiful effect which the complete and undamaged structure must formerly have derived from its details. The lightest portions are of white marble, while the darker ones are of red sandstone. The contrast of these materials enhances the value of the decoration cut into them. The juxtaposition of the two columns in the gateway, although many examples of such arrangement exist, together with the minute ornament upon their exposed sides, is pleasing.
