"When Fancy makes superior Flight her Aim, / Wing'd with this vig'rous, clear seraphick Flame, / She ranges Nature's universal Frame; / Bright Seeds of Thought from various Objects takes, / Whence her fair Scenes and Images she makes: / Spirits so swift, so fine, so bold, so strong, / Gave Milton Genius fit for Milton's Song."
— Blackmore, Sir Richard (1654-1729)
And give just Vigour to the bounding Flood.
The vital Streams with due impulsive Force
Spring from the Heart, and triumph in their Course;
Rarely a dull unagitated Mass
Do's lazy linger in its circling Race:
Nor do's a flaming rapid Torrent fry
The winding Tubes, and leave the Muscles dry;
While the mild Dews, forc'd with too great a Fire,
Desert the Limbs, and thro' the Pores perspire.
The Purple Streams, warm to a just Degree,
From Dregs and unconcocted Juices free,
As they pervade the Channels of the Brain,
Their purer Parts thro' the fine Meshes strain.
These active Liquors, which Admission find
Thro' the strait Paths, and leave the coarse behind,
Swift to the inmost Rooms their Passage beat,
And crowd around the Soul's Imperial Seat;
Of subtile Matter form'd, refin'd and bright,
As Light'ning sprightly, and serene as Light,
Watching their Soveraign's Nod, they ready stand
Apt to perform the Mind's supream Command.
Such noble Vital Instruments are fit
For Reason's Works, and beauteous Turns of Wit.
With finer Strokes they move the tender Strings
Tun'd in the Brain, whence clear Perception springs.
When Fancy makes superior Flight her Aim,
Wing'd with this vig'rous, clear seraphick Flame,
She ranges Nature's universal Frame;
Bright Seeds of Thought from various Objects takes,
Whence her fair Scenes and Images she makes:
Spirits so swift, so fine, so bold, so strong,
Gave Milton Genius fit for Milton's Song.
