The twentieth century had experienced the development of abstract art. The basic symbol of his pharmacy is the pill whose geometry and color may vary on artist's discretion without imposing a realistic structure.
In the following of impressionism and expressionism, Hirst appropriates the seasons for a symbolist variation in the colors of his pills. This phase of creativity culminates with four models of pharmaceutical cabinets made in 2002 in stainless steel and glass. Each of these installations, 183 x 274 x 10 cm, displays several thousand of pills painted in various colors with a visual effect doubled by a back mirror wall.
Until 2008, Hirst managed to convince the art market about his mysticism. The 2002 Lullaby Spring cabinet was sold for £ 9.6M including premium by Sotheby's on June 21, 2007 over a lower estimate of £ 3M.
This success encouraged Hirst to produce new cabinets which were sold almost immediately at auction with grandiloquent titles by Sotheby's, respectively $ 7.1 million including premium on 14 February 2008 and £ 5.2 million including premium on 15 September 2008.
A Lullaby Winter executed in 2002 was sold for $ 7.4 million including premium by Christie's on 16 May 2007. Made in the same year and dimensions, the Lullaby Winter for sale on February 11 in London by Christie's has another provenance, establishing that each cabinet was not a unique piece. It is estimated £ 2.5 million, lot 21.
