So, as title say, how would person from city of Rome plan his trip to "foreign" (but Roman) lands. Did they have any kind of "travel agency"? Is it possible to know how much time I will need, or I just need to "go on adventure".
Rome isn't my specialty, and the UI for this is a bit clunky, but you might find some of what you're interested in by playing with Stanford's Geospatial Model of the Roman Mediterranean.
