A grey wall, a green ruin, rusty pike,

Make my soul pass the equinoctial line

Between the present and past worlds, and hover

Upon their airy confines, half-seas-over.

Which Drachenfels[550] frowns over like a spectre

Of the good feudal times for ever gone,

On which I have not time just now to lecture.
