SOURCEHierocles’ directory, titled Synekdemos (“Travel Companion”), which dates to the early years of Justinian, is the most comprehensive source we have regarding the Early Byzantine administrative division.[1] Since it does not mention the regulations made with novella number 31, which we discussed in our previous article, the latest possible date must be 535. With the code of law published in 536, two new provinces called Upper Armenia and Fourth Armenia would be established, the Pontos Polemoniakos province would be abolished, its west would be annexed to the old First Armenia, its east to the newly established Upper Armenia, and the recently established Mesopotamia province would be included in Fourth Armenia, at least for a while. We indicated these regulations after Hierocles with green and orange border lines on the map.The work provides a list of ‘cities’ (poleis) in each province. We have indicated 346 of these cities, whose locations are known, with a letter code on our map. We did not show about forty settlements whose locations are unknown, and about twenty-five insignificant settlements in order to avoid congestion on the map.We followed this method in coloring: 1) We colored the district where each settlement included in the province is located. 2) Even if a settlement name is not mentioned, we gave the same color to the districts through which the shortest road between two settlements included in the province passes. For example, since Kayseri and Yahyalı are in the Kappadokia I province, we also counted Develi in Kappadokia I, even though no settlement was mentioned. 3) We left the marginal districts, which are outside the network of cities and whose affiliation to which province is not specified, in gray.This visual arrangement is interesting in terms of reminding us that a large part of Anatolia was cut off from urban culture (and probably from central administration) even at the peak of Late Antiquity.We added a few places that we know were significant settlements in the 6th century, even though they were not mentioned in the Synekdemos for some reason, in parentheses, such as (Ko) = Kotyeia.The complete list of places indicated by letter codes on the map is in the attached Excel table.[1] Hieroclis Synecdemus, ed.
