Sculpture is the art of creating three-dimensional forms using various materials and techniques. From prehistoric figurines to modern installations, sculptors have shaped clay, carved stone, and welded metal to bring their visions to life. Key concepts in sculpture include additive and subtractive techniques, relief and in-the-round forms, and the use of armatures and maquettes. Materials range from traditional clay and marble to modern plastics and found objects, each requiring specific tools and skills.
