Ipousteguy trained as a painter and made stained glass windows, but in 1949 he turned exclusively to sculpture. His sculptures were at first abstract and geometric but around 1955 his forms became lumpier and more related to the human figure. 'Earth' was Ipousteguy's first life-size sculpture of a human figure, and it was followed in 1963 by another, entitled 'Man'. Ipousteguy wrote of 'Earth': 'this sculpture is limited to a torso and the face is hidden under the facets of a helmet .... although Earth has two legs, her arms are not completely detached from her body. One has to wait for Man in 1963 for the limbs to separate and spread out.'
