The publication of the journal began at the Institute for Byzantine Research (IBR) of the National Hellenic Research Foundation in 1966 under the title ΣΥΜΜΕΙΚΤΑ. Since that time seventeen volumes of the journal have been published, approximately one every two years. The journal is the primary publication medium for research carried out at the Section of Byzantine Research, either by its own research staff or by external collaborators. The focus of ΣΥΜΜΕΙΚΤΑ laid mostly in Byzantine history, literature and archival research. In 2007 IBR reviewed the journal’s mission, and decided to expand its scope and open it up to the international scholarly community engaged in Byzantine Studies. In its new form, ΒΥΖΑΝΤΙΝΑ SΥΜΜΕΙΚΤΑ is primarily an online journal with a print edition appearing at the end of every year.
