Italy, being part of the Greek culture before becoming the Roman Empire, was really the birthplace of the marionette. Marionette performances were not just for children, however. They were morality plays for the mostly illiterate masses. Political themed satires would also be portrayed in marionette performances--throwing insults or lewd behavior by marionettes was easier to take from a doll than if delivered by a human performer. Perhaps people made decisions on political matters by watching marionette shows, the same way peoples' political views can be shaped by watching the Daily Show today.
In Greece and Rome, clay and ivory dolls dated from 500 BC had articulated arms and legs, with an iron rod extending from the top of their heads. The rod was used to manipulate the doll from above, the same method used in classical Sicilian puppetry. In Sicily, romantic poems were performed in traditional puppet theaters with hand-made marionettes of wood, an art form called L'Opera dei Pupi (Opera of the puppets). Both puppetry and L'Opera dei Pupi and the Sicilian tradition of Cantastori (singers of tales) are rooted in the troubadour tradition in Sicily during the reign of Frederick II, Holy Roman Emperor, in the first half of the 13th century. Still today, you can see this form of puppetry in the puppet theaters of Palermo.
The marionettes, which take the form of knights in armor, sword and shield, told their stories and spread throughout Sicily. The shows depicted their amazing feats in small theaters or in the piazza of towns. There were tales of war, rebellion, boasting chivalry. The knights defended their religion, a beloved woman or their lords. They always fought on the side of Right.
In the 17th century, not long after they had become wildly popular in Italy, marionette performances spread throughout Europe and to England, where Italian puppeteers would exhibit their performances. Marionette were elevated into high art in Czechoslovakia and Germany, where still today they perform full blown operas.
And in Sicily, you can still see the "rod" type of marionette show performed. Taking in a marionette show is is a definite must-do for a visit to Sicily. Here are a couple of links...
