This Austrian stamp, issued in 1981, commemorates the 16th International Congress of Byzantine Studies (Byzantinistenkongress). The design, based on a Byzantine iconographic style, features the Theotokos (Virgin Mary) enthroned with the Christ Child, surrounded by angels and saints in rich gold, red, and blue tones. The text "REPUBLIC ÖSTERREICH" appears at the top, with the denomination of 6 Schilling. Artist A. Pilch captured the intricate spiritual symbolism associated with Byzantine art. The stamp honors Austria’s role in hosting this scholarly event and celebrating Byzantine cultural heritage.
