Maps are the material of Manfred Peckl's large-sized collages maps. He takes world maps and sky maps from conventional geography atlases and cuts them into minute pieces, which he then puts together into a new picture, by gluing together ten thousands of paper bits. When one speaks of materials, one commonly understands this to mean physical texture that will lend and give an artwork shape and form and that communicates aesthetic qualities, on account of the characteristics of its material. The onlooker perceives it not only visually but also physically, with the totality of his/her senses. Natural materials, industrial products, the human body, refuse or light - artists will use almost anything as a material. Yet, can we consider maps also as a material according to this definition? Maps are not only a drawing, or a colorful print on paper. They are also a cultural technique, which combines skills to abstract symbols, scientific findings and technical applications in order to make the world appear as topography. It is therefore appropriate to - at least - bear in mind with a few thoughts which processes of abstraction are at the basis of this cultural technique of charting maps.
