Central Places and Major Roads in the Peloponnese

The technique of Graph Theory is described and applied to the ancient road system of the Peloponnese, using the network described in the Peutinger Table, and compared with George Gennadius' map of 1822. The result demonstrates the relative importance of centres in the Peloponnese during the Roman period, and the modification to the pattern of road usage resulting from sea communications. Details of a computer programme for the necessary calculations are given in an appendix.
