The umbrageous woods are left—how far beneath!
But lo! where darkness seems to guard the mouth
Of yon wild cave, whose jaggèd brows are fringed
With flaccid threads of ivy, in the still
And sultry air, depending motionless.

(As whoso enters shall ere long perceive)
By stealthy influx of the timid day
Mingling with night, such twilight to compose
As Numa loved; when, in the Egerian grot,
