It was not till Thomson began to publish _The Seasons_ in 1726 that the development was complete in poetry. Thomson is a difficult poet to appreciate rightly, for though his subject was 'nature' his method was often as conventional and artificial as that of any Augustan; but he was a lover of the fields and woods, and his imagination, if it is not very powerful, is often very sincere. What was begun by Thomson was carried on with greater sincerity and reality by Cowper, and was transformed by the imagination of Gray and Collins. We sometimes think of this development as specifically English, and it is true that in Wordsworth and Shelley the poetry of nature grew into something which is unique and unmatched, but we must not think of the poetry of Wordsworth as though it were the only form under which nature can be presented. That would be to ignore the qualities, in England of Keats and Tennyson, and in Europe of great artists in whom the treatment of nature assumed other forms. The great poetry of nature began in England, but it was carried on in all the European countries, and for more than a century it was dominated mainly by the genius of Rousseau in France and of Goethe in Germany. I cannot here pretend to deal with the treatment of nature in Rousseau, or with the outcome of his influence first in Bernardin de Saint-Pierre and Chateaubriand, and then in the elegiac beauty of Lamartine and de Musset's _Nuits_; nor can I deal with the poetry of nature in Goethe, and its lesser but often beautiful expression in the German 'Romanticists', and in Heine. It is only possible here to remind ourselves that neither the poetry nor the painting of nature belongs to any one country, but is an intimate part of all modern art. * * * * *
