Now let us leave this Earth, and lift our Eye
To the large Convex of yon' Azure Sky:
Behold it like an ample Curtain spread,
Now streak'd and glowing with the Morning Red;
Anon at Noon in flaming Yellow bright,
And chusing Sable for the peaceful Night.
Ask Reason now, whence Light and Shade were giv'n,
And whence this great Variety of Heav'n:
Reason our Guide, what can She more reply,
Than that the Sun illuminates the Sky;
Than that Night rises from his absent Ray,
And his returning Lustre kindles Day?
