When first young Maro in his boundless mind, [130]
A work to outlast immortal Rome designed,
Perhaps he seemed above the critic's law
And but from nature's fountain scorned to draw
But when to examine every part he came
Nature and Homer were he found the same
Convinced, amazed, he checks the bold design
And rules as strict his labored work confine
As if the Stagirite o'erlooked each line [138]
Learn hence for ancient rules a just esteem,
To copy nature is to copy them.

Some beauties yet no precepts can declare,
For there's a happiness as well as care.
Music resembles poetry--in each
Are nameless graces which no methods teach,
And which a master hand alone can reach
If, where the rules not far enough extend
(Since rules were made but to promote their end),
Some lucky license answer to the full
The intent proposed that license is a rule.
Thus Pegasus a nearer way to take
May boldly deviate from the common track
Great wits sometimes may gloriously offend,
And rise to faults true critics dare not mend,
From vulgar bounds with brave disorder part,
And snatch a grace beyond the reach of art,
Which without passing through the judgment gains
The heart and all its end at once attains.
