roman soliders in the south of france would pick a man during saturnalia and he would live like a nobleman for a month. after the month they would cut his throat on "the altar of saturn."
This was also a basis for the book/film "The Wicker Man". The May King of folk celebrations is also a survival of this. One also sees a connection to the archetype of "The Fool" present in Tarot imagery.
There is a particular medieval mystery play of this myth that portrays the symbolic death of the Fool, who soon rises up in rebirth at the climax of the play, while the chorus sings an interesting song laden with occult interpretation. I cannot remember the name of it now, and am seemingly unable to find reference to it in my books at the moment. Maybe someone else can help me out.
