ORBIS: The Stanford Geospatial Network Model of the Roman World (from now on: Orbis) is an interactive scholarly web application that provides a simulation model of travel and transport cost in the Roman Empire around 200 CE. Walter Scheidel and his team at Stanford University designed and launched the site in 2011–12, and the project saw a significant upgrade in 2014 (the old version is still available). The project is currently concluded.
ToposText is a set of tools that projects the geographic elements of ancient texts onto a mapping of the ancient world. Users can follow a classical reference from place-to-text, or from text-to-place. Zooming in on Thebes and clicking on “Cadmeia,” for example, takes us to 63 text entries, such as the Bios Ellados of Heracleides Criticus; clicking on Bios Ellados takes us to 36 map locations through 78 text references. The text is displayed in public-domain English translation (default) with a link to the original ancient Greek (in this case, at Bibliotheca Augustana). The places are located through a Google Map interface.
