Volume 11 of the series "Tabula Imperii Byzantini (TIB)" deals with the historical geography of the Southern part of the region, which since Antiquity is known as Macedonia. The region is situated in Northern Greece between Epirus, Thessaly and Thrace, which have been researched and published in the previous volumes 1, 3 and 6 of the TIB. The Northern part of the historical region of Macedonia ("Macedonia, Northern Part") is written by Mihailo Popovic as forthcoming volume TIB 16, which will contain a detailed and comprehensive introduction for both volumes (TIB 11 and 16). TIB 11 focuses on the period from the beginning of the 4th century until the 15th century and contains data on the settlements, place names, the monasteries and their landed property, mountains, rivers, lakes as well as the monuments and archaeological remains. Following a short introduction and a geographical outline, all of these data sets are presented in the form of headwords in alphabetical order. The city of Thessalonica was the political, military, economic and cultural centre of the entire region. The area of research of TIB 11 is also including the Athos Peninsula, which became a center of monasticism and spirituality in the 10th century. The research is based on the written sources, on the monuments as well as archaeological remains, on place names, on the state of the landscape itself and on observations of the author during surveys in the area of research. A register of toponyms and a subject index are completing the volume. Moreover, a map of the entire region (1:800,000) and in addition three detailed maps (1:400,000) are provided.
