Simon Starling's two-part work documents a series of interconnected journeys that explore the transformation and movement of materials across time and geography. The first component harnesses solar energy collected on the Suriname River to propel an aluminium boat through Amsterdam's canals, tracing the colonial and industrial histories embedded in the metal itself. The second component completes a poetic cycle by returning to Les Baux de Provence — the site where bauxite, the ore from which aluminium is derived, was first discovered — collecting raw material using an aluminium bicycle, thus connecting the refined product back to its geological origins.
