I have a question on History Stack Exchange which noone has been able to answer yet. Someone has suggested I try this SE site, so here goes.
There is a theory put forward by Benedetto, in his 1928 edition of 'Il Milione', the Italian title of one of the versions of Marco Polo's book about his voyage to China and back. According to the author, the association of 'Il Milione' both as title of the book, and with Marco Polo himself is that it originated in 'the Venetian Sestiere of Emilione'. (as quoted in works by Markus and Munkler).
I haven't been able to verify Benedetto's account directly, to see whether he meant a Venetian sestiere, or a region near Venice (eg Emilia-Romagna / Reggio Emilia / Castelfranco Emilia) nor have I been able to find any mention of a Venetian Sestiere called 'Emilione'.
So - my questions are:
1) Is there any record of such a district existing in Venice? I can find no reference to it on contemporary or historic maps I've looked at to date. Nor have I found a reference to a Church of Santa Emilia there, for example.
2) Is there any evidence to connect the Polo family with any of the 'Emilia' regions?
Grazie per il vostro aiuto!
