Think'st thou existence doth depend on time?
It doth; but actions are our epochs: mine
Have made my days and nights imperishable
Endless, and all alike, as sands on the shore
Innumerable atoms; and one desert
Barren and cold, on which the wild waves break,
But nothing rests, save carcases and wrecks,
Rocks, and the salt-surf weeds of bitterness.

Act II, scene i - Manfred (1817)
