The book, originally published in Russian as Kartografiia khristianskogo srednevekovia (Moscow: Vostachnaia literature, 1999), offers an analysis of 198 Western European and Byzantine maps that date between the eighth and thirteenth centuries and contain information about the north and northeast of the inhabited world. The maps are divided into fifteen groups. Each group of maps is discussed in its separate chapter and all the relevant place names and other legends on the maps are transcribed and translated into English. Included in the book are comprehensive glossaries, which comprise the names of persons, places, ethnicities, and animals, and provide commentaries on the cartographic legends. The book features reproductions of individual maps and their details.
