The best of Hirst

Of the thousands of works in a 20-year career, Damien Hirst yesterday listed just four he regards as "important".

A Thousand Years, 1990
A glass case in which flies hatch from maggots feeding on rotten meat, only to be zapped by an electrical insect killer. Bought back by the artist when Charles Saatchi sold off his Hirst collection.
The Physical Impossibility of Death in the Mind of Someone Living, 1991
Better known as Shark, originally bought by Charles Saatchi for £50,000, remade two years ago after it was sold for a reported £6m to American collector Steve Cohen.

For the Love of God, 2007
Platinum cast of a human skull encrusted with diamonds, priced at £50m. Mainly bought by an investment consortium with the artist retaining part ownership.

The Golden Calf, 2008
Star of the Beautiful Inside My Head Forever collection to be auctioned at Sotheby's next week. Bullock with solid gold hooves and golden disc fixed between golden horns, in tank with gold plated frame. Value estimated at up to £12m.
