My friend Ka-Tong Lim has posted a link to a website (Orbis: The Stanford Geospatial Network Model of the Roman World) that some might find helpful for studying the New Testament as it relates to the geography. There is also a tutorial on how to use it. Ka-Tong states,
"I seldom say this but here is a must see (must use, must share) site for students of the Bible. You can easily find out how long it would take to travel from point to point in the Roman World. For example, it would have taken at least a week to go from Jerusalem to Antioch. Note that ancient names are used (Jerusalem is spelled Ierusalem; Rome, Roma; Corinth, Corinthus, etc.)"
