On 31 December 1999, during the fireworks that accompanied the celebration of the millennium, thieves used scaffolding on an adjoining building to climb onto the roof of the Ashmolean Museum and stole Cézanne’s landscape painting View of Auvers-sur-Oise. Valued at £3 million, the painting has been described as an important work illustrating the transition from early to mature Cézanne painting.[48] As the thieves ignored other works in the same room, and the stolen Cézanne has not been offered for sale, it is speculated that this was a case of an artwork stolen to order.[49][50]
