“The contour of a river bank, the horizon line, the line of the ‘glass half full’ are inventions. The oceans are all interconnected, in a continuous mass, as are the rivers and the streams, and so on and so forth throughout the land. If there are no lines, how can we delimit territories? Or, in other words, if everything is connected, if everything moves constantly and appears to us with different degrees of invisibility, what will be its relevant geography? There are so many different waters: fresh and salt water; drinking water, irrigation and cleaning water; water courses that serve as a means of transport and a home for so many forms of life; or water that has devastating force. We are therefore taking a radical approach by choosing a single location — Cabedelo do Douro — to try to discern many of these issues and identify the multiple lines (or stains, or colours) that allow them to be represented and that are connected to so many other places and beings. “ - Ivo Poças Martins
