It was by dint of his genius for expression, the gift of finding the one right word, that he became the world's greatest lyrist: what he felt became a poem, what he saw a picture.
To see and to fashion into poetry were one with him, whereas his predecessors had called out the whole artillery of Olympus--nymphs, Oreads, Chloe, Phyllis, Damon, Aurora, Echo, and Zephyr--even the still heavier ordnance of the old Teutonic gods and half-gods, only to repeat stereotyped ideas, and produce descriptions of scenery, without lyric thought and feeling.
But Goethe's genius passed through very evident stages of development, and found forerunners in Lessing and Herder.
Lessing's mind was didactic and critical, not lyric, so that his importance here is a negative one. In laying down the limits of poetry and painting in _Laocoon_, he attacked the error of his day which used poetry for pictures, debasing it to mere descriptions of seasons, places, plants, etc.
He was dealing with fundamental principles when he said:
Simonides called painting dumb poetry, and poetry speaking painting; but ... many modern critics have drawn the crudest conclusions possible from this agreement between painting and poetry. At one time they confine poetry within the narrow limits of painting, and at another allow painting to fill the whole wide sphere of poetry.... This fault-finding criticism has partially misled the virtuosos themselves. In poetry a fondness for description, and in painting a fancy for allegory, has arisen from the desire to make the one a speaking picture without really knowing what it can and ought to paint, and the other a dumb poem without having considered in how far painting can express universal ideas without abandoning its proper sphere and degenerating into an arbitrary method of writing.... Since the artist can use but a single moment of ever-changing Nature, and the painter must further confine his study of this one moment to a single point of view, while their works are made not simply to be looked at, but to be contemplated long and often, evidently the most fruitful moment and the most fruitful aspect must be chosen. Now that only is fruitful which allows free play to the imagination. The more we see, the more we must be able to imagine; and the more we imagine, the more we must think we see.
