We are continuing our series of studies regarding the maps of Roman Dacia with this short note regarding the representation of Dacia in the Barrington Atlas of the Greek and Roman world. Edited by Richard J.A. Talbert, this atlas was published in 2000 in a large format, containing 175 pages and 102 full-color maps. The work contains a Map-by-Map Directory, available online. This is in fact an index which provides information about each place (settlement, locality) recorded on the maps. We discuss the details of the Map 21 Dacia-Moesia in our study
