Olafur Eliasson Your black horizon / Your activity horizon (2005)

In a windowless pavilion a thin horizontal line directed through a narrow gap at eye level serves as the primary light source. The light is constantly changing colors and rotates through the color spectrum every few minutes. The light installation was calibrated to the specific light conditions of Venice. While Your activity horizon tried to capture the northern light of Iceland, Your black horizon seizes the Mediterranean light of the laguna. Accurate light recordings have been taken from sunrise to sunset to study the spectrum of light and its intensity.

Catherine Bertola Unseen by all but me alone (2009)

This exhibition reveals a constant theme within Bertola’s work by drawing on the historic role of women and craft production. Bertola celebrates the skill and beauty prevalent to historical genres of craft and the decorative arts, and draws upon a legacy of collective struggle of women; and the presence of personal triumph and liberation that is often overlooked by history.

Unseen by all but me alone consists of a series of delicate handmade golden cobwebs that infiltrate the nooks and crannies of the bare and empty gallery space. With its roots in the origins of female labour the title is taken from a song, sung by Habetrot (a mythological figure in Anglo-Celtic folklore associated with spinning and healing and symbolised by the spinning wheel, wool, and the spiders web) in the story of Habetrot and the Scantlie Mab, a pagan tale that uses spinning as a metaphor and measure for a woman’s virtue. Bertola’s delicately spun webs reclaim space from the absence of human activity, and through their material value announce both a relationship with organic creation associated with neglect and the passing of time, and a
celebration of luxury and silent splendour.

Multiple shadow house, Olafur Eliasson (2010)

A simple, purpose-built structure, the work Multiple shadow house consists of multicolored lamps in rows shining onto several large projection screens. When a body enters the space and begins to interact with this light installation beautiful and subtle overlaid visions of their shadow fan across the screens – as they move around forward and backward the image is thus altered and can be manipulated. In this way the project is a creative collaboration between the artist, viewer, space and technology. via
