The nativity scene may not accurately reflect gospel events. With no basis in the gospels, for example, the shepherds, the Magi, and the ox and ass may be displayed together at the manger. Some traditions bring other scriptural characters to the nativity scene such as Adam and Eve and the serpent, Noah and his animals, the twelve sons of Jacob, the twelve prophets and the twelve apostles. The art form can be traced back to eighteenth-century Naples, Italy. Neapolitan nativity scenes do not represent Palestine at the time of Jesus but the life of the Naples of 1700, during the Bourbon period. Families competed with each other to produce the most elegant and elaborate scenes and so, next to the Child Jesus, to the Holy Family and the shepherds, were placed ladies and gentlemen of the nobility, representatives of the bourgeoisie of the time, vendors with their banks and miniatures of cheese, bread, sheep, pigs, ducks or geese, and typical figures of the time like gypsy predicting the future, people playing cards, housewives doing shopping, dogs, cats and chickens.
