from whose all dateless tombs arose
          Pharaohs from their long repose,
And shook within their pyramids to hear
A new Cambyses thundering in their ear;
While the dark shades of Forty Ages stood
Like startled giants by Nile's famous flood[279];
Or from the Pyramid's tall pinnacle
Beheld the desert peopled, as from hell,
With clashing hosts, who strewed the barren sand,
To re-manure the uncultivated land!
