I'd like to know because I couldn't find anything really talking about how they actually did it in the books I checked out from the library. I'm writing a paper on the creation of Venice, how they made it, why, where did they come from and all that. My Writing professor told me about two books but both of them have no more than a page of content on the subject and I need three sources from physical books/articles. I need to know what books I should be reading for this.
