Byzantine and post-byzantine sources on medieval Bosnia, its area and position

This article discusses the historical and geographical characteristics of medieval Bosnia, its area and position presented in the perception of Byzantine and post-Byzantine sources. It is characteristic that all these sources, regardless of whether they originated in the 10th, 12th, or 15th century or in the centuries after the collapse of the Byzantine Empire offered testimony of the territory of Bosnia. The presentations are sometimes a bit distorted and unrealistic, and their names are based on ancient standards. Data provided by the source material speaking of the appearance of Bosnia and medieval towns in its territory, were named differently in Byzantine sources.
