Henry Moore draws his artistic inspiration from natural forms found in nature, such as roots, bones or stones. His sculptures borrow from these flowing forms, inviting to view the works from all sides, but also to perceive their respective surroundings in a new and more conscious way through a change of perspective. Another source for many of his sculptures, such as the Mother and Child or the Family Groups, are his drawings, which were made during the Second World War in the London Underground. Moore impressively transfers the deep human moments they depict from paper to the third dimension. Moore worked with so-called "marquettes" (sketches), palm-sized sculptures that allowed him to check the implementation of his idea, the proportions and the effect in space.
