I am currently researching what daily life would be for citizens of Venice (the city, not the wider territories controlled by the city), and having trouble finding good sources. I've found plenty of books on the history of the line of Doges, the city's various wars with the Ottoman Empire, political jousts with the papacy and other larger historical facts, but more intimate and personal details remain elusive. I am hoping someone has good ideas for some books or articles which might provide such details.

Some of the questions I'm looking to answer include: How was the city policed? How densely trafficked were city streets and paths vs. canals? What would the diet of a regular (IE non-aristocratic) citizen consist of? As a mercantile city, how many different languages might one expect to encounter? At this time how much construction would have been going on? What materials were buildings at this time composed of? Stone? Plaster? Wood? What kind?

Any help you all could offer would be greatly appreciated.
