And changing, without care of sound or dress,
Strephon and Phyllis, into Tom and Bess.
'Twixt these extremes 'tis hard to keep the right;
For guides take Virgil, and read Theocrite:
Be their just writings, by the Gods inspired,
Your constant pattern, practised, and admired.
By them alone you'll easily comprehend
How poets, without shame, may condescend
To sing of gardens, fields, of flowers, and fruit,
To stir up shepherds, and to tune the flute;
