Mistero Buffo and it's themes

Mistero Buffo was originally performed between 1969-1999. 'Fo's solo pièce cèlèbre, titled Mistero Buffo and performed across Europe, Canada and Latin America over a 30 year period, is recognised as one of the most controversial and popular spectacles in postwar European theatre and has been denounced by the Vatican as 'the most blasphemous show in the history of television'. (http://en.wikipedia.org/wiki/Mistero_Buffo)

It takes its style from that of commedia dell'arte characterised by the use of masks. In my opinion they are very reminiscent of that of a harlequin.

Themes

The theme of the play is the idiocy of organised religion; it is not intended to insult the religion but more what it becomes once people and politics take it over. This theme links into other themes of right and wrong. These themes are shown through the actions undertaken by the church in the name of Catholicism despite them being against what was originally taught. 
The theme of morality is shown in most of the scenes featuring soldiers. The question being raised is 'is it moral to do something that is 'wrong' because of an organisation that is widely considered to be good instructs you to?'
Other themes include life and death, grief and being human. In various scenes the characters main objective is the fear of imminent death and the hope of a better life.

The play is written in a didactic style to educate the audience as well as entertain.
