Lamia [Left to herself]

Left to herself, the serpent now began
To change; her elfin blood in madness ran,
Her mouth foam’d, and the grass, therewith besprent,
Wither’d at dew so sweet and virulent;
Her eyes in torture fix’d, and anguish drear,
Hot, glaz’d, and wide, with lid-lashes all sear,
Flash'd phosphor and sharp sparks, without one cooling tear.
The colours all inflam’d throughout her train,
She writh’d about, convuls’d with scarlet pain:
A deep volcanian yellow took the place
Of all her milder-mooned body’s grace;
And, as the lava ravishes the mead,
Spoilt all her silver mail, and golden brede;
Made gloom of all her frecklings, streaks and bars,
Eclips’d her crescents, and lick’d up her stars:
So that, in moments few, she was undrest
Of all her sapphires, greens, and amethyst,
And rubious-argent: of all these bereft,
Nothing but pain and ugliness were left.

John Keats
