In the spring of 1785 he writes to a friend in a way that shows him fully aware of his new method of studying nature, which he recognized was a reading of her phenomena: 'I can't tell you how the Book of Nature is becoming readable to me. My long practice in spelling has helped me; it now suddenly works, and my quiet joy is inexpressible.' Again in the summer of the following year: 'It is a growing aware of the Form with which again and again nature plays, and, in playing, brings forth manifold life.' Then Goethe went on his famous journey to Italy which was to bear such significant fruit for his inner life, both in art and in science. At Michaelmas, 1786, he reports from his visit to the botanical garden in Padua that 'the thought becomes more and more living that it may be possible out of one form to develop all plant forms'. At this moment Goethe felt so near to the basic conception of the plant for which he was seeking, that he already christened it with a special name. The term he coined for it is Urpflanze, literally rendered archetypal plant, or ur-plant, as we propose quite simply to call it.6 It was the rich tropical and sub-tropical vegetation in the botanical gardens in Palermo that helped Goethe to his decisive observations. The peculiar nature of the warmer regions of the earth enables the spirit to reveal itself more intensively than is possible in the temperate zone. Thus in tropical vegetation many things come before the eye which otherwise remain undisclosed, and then can be detected only through an effort of active thought. From this point of view, tropical vegetation is 'abnormal' in the same sense as was the proliferated rose which confirmed for Goethe's physical perception that inner law of plant-growth which had already become clear to his mind. During his sojourn in Palermo in the spring of 1787 Goethe writes in his notebook: 'There must be one (ur-plant): how otherwise could we recognize this or that formation to be a plant unless they were all formed after one pattern?' Soon after this, he writes in a letter to the poet Herder, one of his friends in Weimar: 'Further, I must confide to you that I am quite close to the secret of plant creation, and that it is the simplest thing imaginable. The ur-plant will be the strangest creature in the world, for which nature herself should envy me. With this model and the key to it one will be able to invent plants ad infinitum; they would be consistent; that is to say, though non-existing, they would be capable of existing, being no shades or semblances of the painter or poet, but possessing truth and necessity. The same law will be capable of extension to all living things.' *
