The earliest dolls were made from available materials such as clay, stone, wood, bone, ivory, leather, or wax. Archaeological evidence places dolls as the foremost candidate for the oldest known toy. Wooden paddle dolls have been found in Egyptian tombs dating to as early as the 21st century BC. Dolls with movable limbs and removable clothing date back to at least 200 BC. Archaeologists have discovered Greek dolls made of clay and articulated at the hips and shoulders. Rag dolls and stuffed animals were probably also popular, but no known examples of these have survived to the present day. Stories from ancient Greece around 100 AD show that dolls were used by little girls as playthings. In ancient Rome, dolls were made of clay, wood or ivory. Dolls have been found in the graves of Roman children. Like children today, the younger members of Roman civilization would have dressed their dolls according to the latest fashions. In Greece and Rome, it was customary for boys to dedicate their toys to the gods when they reached puberty and for girls to dedicate their toys to the goddesses when they married. Rag dolls are traditionally home-made from spare scraps of cloth material. Roman rag dolls have been found dating back to 300 BC.
