Dusky and huge, enlarging on the sight,

Nature's volcanic Amphitheatre, [22.B.]

Chimæra's Alps extend from left to right:

Beneath, a living valley seems to stir;

Flocks play, trees wave, streams flow, the mountain-fir

Nodding above; behold black Acheron! [23.B.]

Once consecrated to the sepulchre.

Pluto! if this be Hell I look upon,

Close shamed Elysium's gates, my shade shall seek for none[fb].
