The third pyramid is of much smaller dimensions than the two others, but beautifully constructed. It was the work, as is proved by the discovery of his name, of Mycerinus or Mencheres, whose wooden coffin in the British Museum, very simple, and unornamented, as well as the desiccated body, supposed to be that of the monarch himself, has probably attracted the notice of our readers. This pyramid is double, _i. e._, eased over with a distinct covering. Besides these principal ones, there are still standing other and smaller pyramids, more or less entire, grouped about these larger ones, and forming a portion of this stupendous Necropolis of Memphis. * * * * * THE GREAT HALL AT KARNAK.--We had spent so much time in the examination of Luxor, and of the other portions of Karnak, that the evening was advanced when we arrived at the Great Hall. The shadows were creeping solemnly through the intricate recesses of its forest of columns, but the red light rested for a while upon their beautiful flower-shaped capitals, the paintings upon which, scarred and worn as they are by the accidents of 3000 years, still display, under a strong light, much of their original vividness. It is a perfect wilderness of ruin, almost outrunning the wildest imagination or the most fantastic dream. We paced slowly down the central avenue. The bases of the columns are buried among the fallen fragments of the roof and a mass of superincumbent earth; from his hiding-place, amidst which the jackal began to steal forth, and wake the echoes of the ruins with his blood-curdling shriek; while the shadowy bat flitted, spirit-like, from dusky pillar to pillar. From the centre of the hall, whichever way we looked through the deepening gloom, there seemed no end to the labyrinthine ruins. Obelisks and columns, some erect in their pristine beauty, others fallen across, and hurled together in hideous confusion, forming wild arcades of ruin; enormous masses of prostrate walls and propylaea, seemed to have required either to construct or to destroy them the power of a fabled race of giants. Pillars, obelisks, and walls of this immense hall, were covered with the forms of monarchs who reigned, and of the gods who were once worshiped within it. Involuntarily the mind goes back, in gazing on them, to the period of its original splendor, when Rameses in triumph returned from his oriental conquests--pictures the pile in all its completeness, the hall of a hundred and thirty columns with its superb roof, glittering in all the vivid beauty of its paintings, thronged with monarchs, and priests, and worshipers, and devoted to splendid and gorgeous ceremonies.
