mercutio florio

Years ago, while book-grazing at the local regional library facility, I came across a curious typescript called William Shakespeare, alias Mercutio Florio. Its title page indicated the author was Friderico Georgi, but in the card catalog this was said to be a pseudonym of Franz Maximilian Saalbach. It was published in Heidelberg in 1954. Googling Franz Saalbach dredges up a Heidelberger Geschichtsverein e.V. HGV history page (link) where 17. September 1952: Gründung der HIAG-Kreisgemeinschaft Heidelberg im Bergbräu, Hauptstraße 27. Zum ersten Sprecher wird Franz Saalbach gewählt.. The German Amazon lists the book, but there the author is Erich Gerwien (link). What triggered all of this was running across a theory that Shakespeare was Italian which a couple of Sicilian professors came up with (link). And, as with anything Shakespearean, can the Oxfordists be far off? This final bit is thanks to Languagehat (link).
