The æsthetic writer Sulzer (1750) wrote _On the Beauty of Nature_. Crugot's widely-read work of edification, _Christ in Solitude_ (1761), shewed the same point of view among the mystical and pietist clergy; and Spalding's _Human Vocation_[9] (written with a warmth that reminds one of Gessner) among the rationalists, whom he headed. He says: Nature contains numberless pleasures, which, through my great sensitiveness, nourish my mind... I open eye and ear, and through these openings pleasures flow into my soul from a thousand sides: flowers painted by the hand of Nature, the rich music of the forest, the bright daylight which pours life and light all round me.... How indifferent, tasteless, and dead is all the fantastic glamour of artificial splendour and luxuriance in comparison with the living radiance of the real beautiful world of Nature, with the joyousness, repose, and admiration I feel before a meadow in blossom, a rustling stream, the pleasant awesomeness of night, or of the majesty of innumerable worlds. Even the commonest and most familiar things in Nature give me endless delight, when I feel them with a heart attuned to joy and admiration.... I lose myself, absorbed in delight, in the consideration of all this general beauty, of which I hold myself to be a not disfigured part. Klopstock, the torch-bearer of Germany's greatest poets, owed much of his power of the wing to religion. He introduced that new epoch in the literature of his country which culminated in Goethe. As so often happens in mental development, the reaction against prevailing conditions and the advance to higher ones, in the middle of the eighteenth century, led first of all to the opposite extreme--balance was only reached by degrees. What chiefly made Klopstock a literary reformer was the glowing enthusiasm and powerful imagination which compelled the stiff poetic forms, clumsy as they were, to new rhythm and melodious cadence. And although his style degenerated into mannerism in the _Messias_, for the youthful impetus which had carried his Pegasus over the clouds to the stars could not keep it there without artificial aid, the immense value of his influence remained. He is one of the most interesting representatives, not only of his own, but of all similar periods of exaggerated feelings and ideals. Despite his loftiness of thought and speech, and his seraphic raptures, he was not without a full share of sensuous development, and women's eyes, or a girl's rosy lips, would draw him away from the finest view in the world. A mind so intent upon the noble and beautiful was sure to be enthusiastic about Nature; his correspondence is the best witness to this, and at the same time throws side-lights upon the period.
