Here she comes now

She comes! she comes! the sable throne behold
Of Night primeval, and of Chaos old!
Before her, Fancy's gilded clouds decay,
And all its varying rainbows die away.
Wit shoots in vain its momentary fires,
The meteor drops, and in a flash expires.
As one by one, at dread Medea's strain,
The sick'ning stars fade off th' ethereal plain.

The Dunciad (Book IV), Alexander Pope
