Echidna, the untameable of soul:
Above, a nymph with beauty-blooming cheeks,
And eyes of jetty lustre; but below,
A speckled serpent horrible and huge,
Gorged with blood-banquets, monstrous, hid in caves
Of sacred earth. There in the uttermost depth
Her cavern is, within a vaulted rock:
Alike from mortals and immortals deep
Remote: the gods have there decreed her place
In mansions known to fame. So pent beneath
