A community-built gazetteer and graph of ancient places



Springing from the Classical Atlas Project and the Barrington Atlas of the Greek and Roman World, Pleiades is a historical gazetteer and more. It associates names and locations in time and provides structured information about the quality and provenance of these entities. There is also a graph in Pleiades: names and locations are collected within places and these collections are associated with other geographically connected places. Pleiades also serves as a vocabulary for talking about the geography of the ancient world within Linked Data sets and is referenced by research projects such as Google Ancient Places and PELAGIOS.

More about the data ...

Pleiades is one hundred percent open source, one hundred percent openly licensed and one hundred percent editable. Our open source software gets used and improved by a diverse crowd of programmers in the humanities and beyond. Our openly licensed resources have no surprises or encumberances, and their editability allows Pleiades users to correct or enrich resources – thereby tailoring the gazetteer and the entire linked data vocabulary to better meet their own particular needs. Pleiades welcomes your contribution, no matter how small, and we have a number of internal projects to suggest.
