Orbis: The Stanford Geospatial Network Model of the Roman World

Orbis: The Stanford Geospatial Network Model of the Roman World. Scheidel, W. May, 2015.

ORBIS allows us to express ancient Roman communication costs in terms of both time and expense. By simulating movement along the principal routes of the Roman road network, the main navigable rivers, and hundreds of sea routes in the Mediterranean, Black Sea and coastal Atlantic, this interactive model reconstructs the duration and financial cost of travel in antiquity. Taking account of seasonal variation and accommodating a wide range of modes and means of transport, ORBIS reveals the true shape of the Roman world and provides a unique resource for our understanding of premodern history.
