The Greek Madonna (Madonna Greca in Italian) is a Byzantine marble bas-relief sculpture of the Virgin Mary in Ravenna - she is patron saint of the city, the Roman Catholic Archdiocese of Ravenna-Cervia and the Vicariate of the Sea (Vicariato del Mare).
Like many locally famous sculptures, it acquired a legendary origin story, but to art historians it is a Byzantine sculpture, perhaps of the 9th century, that arrived in Ravenna by unknown means by around 1100.
