The 4th UFO Historiography Day was held in Turin on March 11, 2017.
Maurizio Verga introduced a lecture titled The future of the saucer past devoted to a quick overview of the saucer imagery in 1947 backwards until the end of the 19th century. At the end some key points are discussed and a few questions offered for further discussion.
Enjoy the presentation:
