History of metal sculptures

Bronze Metal Art. Nearly all the ancient civilizations used bronze in their art even as its discovery dates back to the time of the Sumerians around 3500 BC. ... It is more popularly used than copper (and brass) to create metal ornaments, sculptures, statues, figurines, plates, chalices, and unique hardware.
even as far back as 7000 B.C. Crude artistic endeavors (hammered metal) can be seen in the Bronze Age. Iron, gold, silver, lead, bronze and copper artifacts have been found at ancient sites in Troy. Metal tools, utensils, dishes and even human figures and masks date back to some of the earliest known civilizations.Sculpture is the branch of the visual arts that operates in three dimensions. It is one of the plastic arts. Durable sculptural processes originally used carving (the removal of material) and modelling (the addition of material, as clay), in stone, metal, ceramics, wood and other materials but, since Modernism, there has been an almost complete freedom of materials and process. A wide variety of materials may be worked by removal such as carving, assembled by welding or modelling, or molded or cast.
