“All things on earth have their term, and, in the most joyous career of their vanity and splendor, their strength fails, and they sink into the dust. All the round world is but a sepulchre; and there is nothing which lives on its surface that shall not be hidden and entombed beneath it. Rivers, torrents, and streams move onward to their destination. Not one flows back to its pleasant source. They rush onward, hastening to bury themselves in the deep bosom of the ocean. The things of yesterday are no more to-day; and the things of to-day shall cease, perhaps, on the morrow.[330] The cemetery is full of the loathsome dust of bodies, once quickened by living souls, who occupied thrones, presided over assemblies, marshalled armies, subdued provinces, arrogated to themselves worship, were puffed up with vainglorious pomp, and power, and empire. “But these glories have all passed away, like the fearful smoke that issues from the throat of Popocatepetl, with no other memorial of their existence than the record on the page of the chronicler. “The great, the wise, the valiant, the beautiful,--alas! where are they now? They are all mingled with the clod; and that which has befallen them shall happen to us, and to those that come after us. Yet let us take courage, illustrious nobles and chieftains, true friends and loyal subjects,--_let us aspire to that heaven where all is eternal and corruption cannot come_.[331] The horrors of the tomb are but the cradle of the Sun, and the dark shadows of death are brilliant lights for the stars.”[332] The mystic import of the last sentence seems to point to that superstition respecting the mansions of the Sun, which forms so beautiful a contrast to the dark features of the Aztec mythology. At length, about the year 1470,[333] Nezahualcoyotl, full of years and honors, felt himself drawing near his end. Almost half a century had elapsed since he mounted the throne of Tezcuco. He had found his kingdom dismembered by faction and bowed to the dust beneath the yoke of a foreign tyrant. He had broken that yoke; had breathed new life into the nation, renewed its ancient institutions, extended wide its domain; had seen it flourishing in all the activity of trade and agriculture, gathering strength from its enlarged resources, and daily advancing higher and higher in the great march of civilization. All this he had seen, and might fairly attribute no small portion of it to his own wise and beneficent rule. His long and glorious day was now drawing to its close; and he contemplated the event with the same serenity which he had shown under the clouds of its morning and in its meridian splendor.
