LONDON.- Five members of the art activist group Culture Beyond Oil today poured non-toxic black oil around the British Museum’s world famous Easter Island sculpture, in protest at BP’s sponsorship of the museum. The group, inspired by Liberate Tate’s intervention at Tate Britain earlier this month, said it had deliberately chosen the giant statue of a human head because it represents the way in which civilizations once considered invincible can collapse in a short period of time. The activists were careful not to pour oil on the sculpture itself, which is seated on a modern stone plinth. Like the Tate, whose trustees meet to discuss their sponsorship arrangements tomorrow, the British Museum receives money from BP on an annual basis. In return the company is able to use the building to hold corporate parties and
