Body fluids in art

A relatively new trend in contemporary art is to use body fluids in art. Examples include:

• The controversial Piss Christ (1987), by Andres Serrano[?], which is a photograph of a crucifix submerged in urine;
• Self (1991, recast 1996) by Marc Quinn, a frozen cast of the artist's head made entirely of his own blood;
• Piss Flowers, by Helen Chadwick (1991-92), are twelve white-enamelled bronzes cast from cavities made by urinating in snow;
• many paintings by Chris Ofili, which make use of elephant dung (from 1992).
• Gilbert and George's The Naked Shit Pictures (1995)
