As thro' the Artist's intervening Glass,
Our Eye observes the distant Planets pass;
A little we discover; but allow,
That more remains unseen, than Art can show:
So whilst our Mind it's Knowledge wou'd improve;
(It's feeble Eye intent on Things above)
High as We may, We lift our Reason up,
By  directed, and confirm'd by :
Yet are We able only to survey
Dawnings of Beams, and Promises of Day.
fuller Effluence mocks our dazl'd Sight;
Too great it's Swiftness, and too strong it's Light.
