If we would copy nature, it may be useful to take this idea along with us, that Pastoral is an image of what they call the golden age: so that we are not to describe our shepherds as shepherds at this day really are, but as they may be conceived then to have been, when the best of men followed the employment. To carry this resemblance yet further, it would not be amiss to give these shepherds some skill in astronomy, as far as it may be useful to that sort of life; and an air of piety to the gods should shine through the poem, which so visibly appears in all the works of antiquity; and it ought to preserve some relish of the old way of writing: the connection should be loose, the narrations and descriptions short, and the periods concise. Yet it is not sufficient that the sentences only be brief; the whole eclogue should be so too: for we cannot suppose poetry in those days to have been the business of men, but their recreation at vacant hours.
But, with respect to the present age, nothing more conduces to make these composures natural, than when some knowledge in rural affairs is discovered. This may be made to appear rather done by chance than on design, and sometimes is best shown by inference; lest, by too much study to seem natural, we destroy that easy simplicity from whence arises the delight. For what is inviting in this sort of poetry proceeds not so much from the idea of that business, as of the tranquillity of a country life.
