its variety. This variety is obtained in a great degree by frequent
comparisons, drawn from the most agreeable objects of the country; by
interrogations to things inanimate; by beautiful digressions, but those
short; sometimes by insisting a little on circumstances; and lastly, by
elegant turns on the words, which render the numbers extremely sweet and
pleasing. As for the numbers themselves, though they are properly of the
heroic measure, they should be the smoothest, the most easy and flowing
imaginable.

It is by rules like these that we ought to judge of pastorals. And since
the instructions given for any art are to be delivered as that art is in
perfection, they must of necessity be derived from those in whom it is
acknowledged so to be. It is therefore from the practice of Theocritus
and Virgil (the only undisputed authors of pastoral) that the critics
have drawn the foregoing notions concerning it.

Theocritus excels all others in nature and simplicity. The subjects of
his 'Idyllia' are purely pastoral; but he is not so exact in his
persons, having introduced reapers and fishermen as well as shepherds.
He is apt to be too long in his descriptions, of which that of the cup
in the first pastoral is a remarkable instance. In the manners he seems
a little defective, for his swains are sometimes abusive and immodest,
and perhaps too much inclining to rusticity; for instance, in his fourth
and fifth 'Idyllia.' But 'tis enough that all others learnt their
excellencies from him, and that his dialect alone has a secret charm in
it, which no other could ever attain.

Virgil, who copies Theocritus, refines upon his original: and in all
points where judgment is principally concerned, he is much superior to
his master.
