This volume offers a key to the sources to, and proper names of the Alans. The scattered nature of sources and their dispersion in time, space and intermediary languages may explain the lack of a comprehensive guide to this important ancient people, a nomadic tribe of Iranian stock, living from one end of the Eurasian steppes to the other. Documents from ancient up to medieval times regularly make, in a wide variety of languages, mention the Alans. With this book the author provides a handbook by collecting, classifying, translating (or summarizing) all reports on the Alans written in Greek, Latin, Medieval Latin, Byzantine, Arabic, Armenian, Catalan, Georgian, Hebrew, Iranian, Mongol, Russian, Syriac and Chinese languages.
