Another Ozymandias

                          Ozymandias

    In Egypt's sandy silence, all alone,
      Stands a gigantic Leg, which far off throws
      The only shadow that the Desart knows:—
    "I am great OZYMANDIAS," saith the stone,
      "The King of Kings; this mighty City shows
    "The wonders of my hand."— The City's gone,—
      Nought but the Leg remaining to disclose
    The site of this forgotten Babylon.

    We wonder,—and some Hunter may express
    Wonder like ours, when thro' the wilderness
      Where London stood, holding the Wolf in chace,
    He meets some fragment huge, and stops to guess
      What powerful but unrecorded race

     Once dwelt in that annihilated place.

Horace Smith (1779-1849).
