We just added links to two databases concerning the classical world:
Connected Contests in the post-classical world
An evolving online research tool to facilitate the study of agonistic networks in the ancient, post-classical world. It is part of a wider research project on the history of athletic and other agonistic festivals from 300 BC-AD 300. (see above under about). This website aims to provide an intuitive database of the many contests of the Greek world, and of the athletes, performers and other participants in these contests. (from description on-site).
Digital Atlas of the Roman Empire
Provided and managed by the Centre for Digital Humanities, University of Gothenburg, Sweden.
In addition, there is a new link to an open access journal dedicated to the Byzantine period and research- The Byzantine Review
