35,000 individual terracotta figures, each between 8 and 26 cm high, installed on the floor of a room facing the viewer.
The figures were sculpted in Cholula, Mexico by about 60 members of a Texca family of brickmakers, under the supervision of the artist.
Ideally the Field is extended through a doorway or round a corner, so that the figures going out of sight leave the impression of an unlimited horde.
Each volunteer was given a portion of the 30 tonnes of clay required, along with some loose instructions specifying the rough size and proportions for the figures.
In 1994, Gormley won the Turner prize with a collection of his work, including Field for the British Isles, shown at the Tate Gallery.
