Orbis Latinus database of latin placenames
Orbis Latinus Online (OLO) is based on the three-part print publication of Orbus Latinus from 1972. This online resource allows you to find the modern equivalent of latin place names, as well as the latin names of modern places. "Modern" is relative, because the geographical descriptors may date back to the original time of writing. More information on this may be found in the editorial notice of the digitised version of Orbus Latinus at the Bayerische Staatsbibliothek in Munich. In OLO, every record has a link to the item in the digitalised copy of Orbus Latinus. This enables you to check each record with the original. All place-names have been automatically geo-referenced with coordinates that allow the places to be located on a map. The manual checking of the automatically generated coordinates is still in progress.
