" It is not without good reason that the literary tradition of pastoral poetry can look back on an almost uninterrupted history of over two thousand years since its beginnings in Hellenism. With the exception of the early Middle Ages, when urban and court culture was extinguished, there have been variants of this poetry in every century. Apart from the thematic material of the novel of chivalry, there is probably no other subject-matter 15 that has occupied the literature of Western Europe for so long and maintained itself against the assaults of rationalism with such tenacity. This long and uninterrupted reign shows that ‘sentimental’ poetry, in Schiller’s sense of the word, plays an incomparably greater part in the history of literature than ‘naïve’ poetry. Even the idylls of Theocritus himself owe their existence not, as might be imagined, to genuine roots in nature and a direct relationship to the life of the common people, but to a reflective feeling for nature and a romantic conception of the common folk, that is, to sentiments which have their origin in a yearning for the remote, the strange and the exotic. The peasant and the shepherd are not enthusiastic about their surroundings or about their daily work. And interest in the life of the simple folk is, as we know, to be sought neither in spatial nor social proximity to the peasantry; it does not arise in the folk itself but in the higher classes, and not in the country but in the big towns and at the courts, in the midst of bustling life and an over-civilized, surfeited society. Even when Theocritus was writing his idylls, the pastoral theme and situation were certainly no longer a novelty; it will already have occurred in the poetry of the primitive pastoral peoples, but doubtless without the note of sentimentality and complacency, and probably also without attempting to describe the outward conditions of the shepherd’s life realistically. Pastoral scenes, although without the lyrical touch of the Idylls, were to be found before Theocritus, at any rate, in the mime. They are a matter of course in the satyr plays, and rural scenes are not unknown even to tragedy. But pastoral scenes and pictures of country life are not enough to produce bucolic poetry; the preconditions for this are, above all, the latent conflict of town and country and the feeling of discomfort with civilization.
