"And, by the fall of Scylla, Glaucus bleeds"

Strait Circe reddens with a guilty shame,
And vows revenge for her rejected flame.
Fierce liking oft a spight as fierce creates;
For love refus'd, without aversion, hates.
To hurt her hapless rival she proceeds;
And, by the fall of Scylla, Glaucus bleeds.
Some fascinating bev'rage now she brews;
Compos'd of deadly drugs, and baneful juice.
At Rhegium she arrives; the ocean braves,
And treads with unwet feet the boiling waves.
Upon the beach a winding bay there lies,
Shelter'd from seas, and shaded from the skies:
This station Scylla chose: a soft retreat
From chilling winds, and raging Cancer's heat.
The vengeful sorc'ress visits this recess;
Her charm infuses, and infects the place.
Soon as the nymph wades in, her nether parts
Turn into dogs; then at her self she starts.
A ghastly horror in her eyes appears;
But yet she knows not, who it is she fears;
In vain she offers from her self to run,
And drags about her what she strives to shun.
Oppress'd with grief the pitying God appears:
And swells the rising surges with his tears;
From the detested sorceress he flies;
Her art reviles, and her address denies:
Whilst hapless Scylla, chang'd to rocks, decrees
Destruction to those barques, that beat the seas.
