During numerous exploratory walks in the south of Spain, I experienced the landscape as a great repository of knowledge encompassing plants and animals as well as sand, fossilized dunes, and volcanic rock. This knowledge draws from the past and the present, from the individual elements of nature as well as their mutual connections. Everything is affected by natural forces such as wind, sun, and water, as well as by those that hold everything together. It is striking that this knowledge is not equally distributed across the landscape, but becomes particularly evident at specific sites that are linked to one another. These places often take the shape of constellations and aggregations of natural objects and energies, similar to the synapses in the brain where information is communicated in the network of nerve cells.
