This survey covers the islands of the North Aegean; Chios, Lesbos, Lemnos, Samothrace, Thasos, Skyros, Tenedos, Eustratios and Imbros and its neighbours. It starts as usual with explanations of the terminology used, and descriptions of the geography and climate of the region. There follows an exploration of historical and administrative development, the Church, economy, traffic routes, and settlement and population, after which comes the gazetteer proper, describing Byzantine-period sites alphabetically, including their history, surviving remains and bibliography.
