Imagination! who can sing thy force?
Or who describe the swiftness of thy course?
Soaring through air to find the bright abode,
Th’ empyreal palace of the thund’ring God,
We on thy pinions can surpass the wind,
And leave the rolling universe behind:
From star to star the mental optics rove,
Measure the skies, and range the realms above.
There in one view we grasp the mighty whole,
Or with new worlds amaze th’ unbounded soul.

Wheatley's poem “On Imagination” was published in Poems on Various Subjects Religious and Moral (A. Bell, 1773). Born in West Africa, at the age of eight Phillis Wheatley was kidnapped, enslaved in New England, and sold to John Wheatley of Boston. More about the short life (1753-1784) and achievements of this amazing person is available here at poets.org and here is a link to several more of her poems.
In poetry, as in mathematics, we celebrate Imagination!
