The irregularly rounded shapes of this relief suggest the forms of natural, growing things. This association is emphasised by the title. Arp saw the relentless growth in nature as an indication of spontaneity and intuition that the artist should emulate. He saw these qualities as necessary antidotes to the rationalism of the modern world. Using forms that had denoted a body in an earlier work, he inverted them so that the legs became the impish ears of a new creature.
