Proxeny Networks of the Ancient World (PNAW) presents an overview of our evidence for these relationships of proxeny in the ancient world, including those recorded in the literary sources as well as the more than two thousand texts inscribed on stone. It accompanies the recent study of this institution published by Oxford University Press, Proxeny and Polis and its purpose is to make this material available in an accessible format which can be corrected and updated as new evidence is published. It makes use of GIS mapping to enable the evidence of links between different communities which this data presents to be explored in an intuitive way. In order to make the search function useable, results are presented in a condensed view with further information available in the form of mouseover dialogue boxes.
