Feldspar – Hadal Zone refers to both the deep ocean and the Earth’s surface: Feldspars are a group of rock-forming minerals that make up the greatest composition of the Earth’s crust, while Hedal Zone is the delineation for the deepest trenches in the ocean and is named after the realm of Hades, the underworld in Greek mythology. In Joey Holder’s work, both territories are merged in an irregular and indefinable visual shape that almost completely covers the exhibition space. But what does the deepest ocean have in common with the Earth’s surface? In trying to create a map of territories of which the human being knows very little about, Joey Holder’s work questions not only the limits of our mapping system, but of science and technology more generally. Here the disappointment comes from the expectations created by the teleological narrative of scientific and technological development, understood as the human ability to create instruments that enhance our capability to study, map and represent the world we live in. Imagination then is the only thing left that can help us to face the unknown.
