_By applying to the custodian, the visitor can ascend to the top_, where a most magnificent view is enjoyed, the only way to get a good idea of its size and oval shape, and where the construction of the upper galleries can be studied. It will be seen that the arches forming the tiers of seats have at some date been filled in with brickwork, of the time of Alexander Severus and the Gordiani. The water-courses for keeping the building cool in hot weather can also be traced. The highest wall of all, the inside brick casing of which is partly gone, is built of fragments evidently not originally intended for the purpose for which they are used, corresponding to a great extent with the construction of the walls upon the area. The Colosseum was for a long time used as a quarry, from which several of the palaces in Rome were built. Should the visitor be fortunate enough to see the ruin under moonlight, or when it is illuminated with Bengal lights, he will see it in its grandeur, for "it will not bear the brightness of the day."
