In the impulse "A Walk in the Forest" I encouraged you to collect and press leaves or flowers or other plant parts to use them for collages. And then, in the impulse “A personal herbarium” you already got to try a simple collage. Now I’d like to talk about the different techniques of collage, their possibilities and versatility. I want to introduce the concept. Collage is a technique that originated in the visual arts. You apply several found pieces of paper onto a canvas or piece of paper to create a new image. The word itself comes from the French "coller" meaning "to glue", and "la colle", which means “glue”, as the technique glues things onto a surface. The collage is of course not only relevant for the visual arts, but later also in literature and the performing arts. There are text collages, music collages, theater collages, film collages, or even text-image collages, as for example by the famous author Herta Müller.

There’s a magic in every beginning. It’ a wonderful energy to start something new. To start a new chapter, a new theme, a new idea, something that wasn't there before. There's a great power in that, in that newness, that unprecedentedness, and that's what we're starting with today. We’re now in this wonderful season of autumn. The colored leaves may have already fallen to the ground in great numbers, and yet autumn is a delight. Maybe the snow is already in the air, and you can literally smell it.

In the last impulse "A Walk in the Forest" I encouraged you to collect and press leaves and other plant parts. You can now use these pressed parts to make collages with natural objects from the realm of plants. The practice of pressing and drying plants is an old one. The oldest surviving herbarium dates back to as early as the 16th century (1524). It’s located in Kassel, Germany. Originally, people dried plants to have decorative material in winter. That’s how the tradition of the herbarium began. Over time, people realized that they could do this with all sorts of plants and that they could systematize the herbarium and add the roots, the buds, the flower heads, and the fruits. They became scientific works. Nowadays there are herbaria worldwide, most of them in Europe and North America. Often, they can be found in botanical gardens or natural history museums. The largest herbaria are in Paris, St. Petersburg, London, St. Louis, Vienna (they were established mainly in the times of the monarchy) and in Berlin.
