Olafur Eliasson was born in 1967 in Copenhagen, Denmark of Icelandic parentage. He attended the Royal Academy of Arts in Copenhagen from 1989 to 1995. He has participated in numerous exhibitions worldwide and his work is represented in public and private collections including the Solomon R Guggenheim Museum, New York, The Museum of Contemporary Art, Los Angeles, the Deste Foundation, Athens and Tate. His installations regularly feature elements appropriated from nature. By introducing ‘natural’ phenomena, such as water, mist or light, into an un specifically cultivated setting, be it a city street or an art gallery, the artist encourages the viewer to reflect upon their understanding and perception of the physical world that surrounds them. In The Weather Project representations of the sun and sky dominate the expanse of the Turbine Hall. A fine mist permeates the space, as if creeping in from the environment outside. Throughout the day, the mist accumulates into faint, cloud-like formations, before dissipating across the space. A glance overhead, to see where the mist might escape, reveals that the ceiling of the Turbine Hall has disappeared, replaced by a reflection of the space below. At the far end of the hall is a giant semi-circular form made up of hundreds of mono-frequency lamps. The arc repeated in the mirror overhead produces a sphere of dazzling radiance linking the real space with the reflection. Generally used in street lighting, mono-frequency lamps emit light at such a narrow frequency that colours other than yellow and black are invisible, thus transforming the visual field around the sun into a vast duotone landscape.
