In ancient Greece and Rome clay and ivory dolls, dated from around 500 BC, were found in children's tombs. These dolls had articulated arms and legs, some of which had an iron rod extending up from the tops of their heads. This rod was used to manipulate the doll from above, exactly as is done today in Sicilian puppetry. A few of these dolls had strings in place of the rods. Some researchers believe these ancient figures were mere toys and not puppets due to their small size.
