The Tate Gallery's pile of bricks
As an aside, the 'Pile of Bricks' is the popular name for some building materials the Tate Gallery bought from Carl Andre in 1972. Andre's so-called minimalist sculpture ('Equivalent VIII') consists of 120 firebricks placed on the floor in a rectangular formation. The Pile isn't always on display. It can be dismantled for storage, but each time it's put on display again the bricks aren't assembled in any particular order, so even if it was a work of art, it isn't really the work originally purchased. The Tate Gallery never recorded the order and orientation in which Andre first arranged them.
The Turner Prize is firmly associated with such 'Conceptual Art'. This is a branch of the visual arts in which an idea takes precedence over the aesthetics and craftsmanship traditionally associated with the great media handed down to us through the centuries (notably drawing, painting, and sculpture). A conceptual artist making an installation or presenting an objet trouvé is not required to demonstrate any skill, except (i) skill in coming up with a gimmick no-one else has thought of before and (ii) skill in self-promotion.
Turner's [Tracey's] unmade bed
When an artist called Tracey hit on the concept of her unmade bed 'graphically illustrating' the "whole human life-cycle in the place where most of us spend our most significant moments" and felt it should win an award for artistic merit, she decided to send it in for the 1999 Turner Prize. Lo, Serota and his arty cronies shortlisted 'My Bed' into the top four entries, undeterred by the fact that this applies to most people's beds. Ah, but wait. Of course. No-one else had thought of it before. The Turner Prize sponsors would love it and Charles Saatchi might like to buy Tracey.co.uk's unmade bed for £150,000.
