De Ceremoniis
The name and place of burial of Eudokia in the Church of the Holy Apostles was recorded in "De Ceremoniis" by Constantine VII. However little else is known of her. She is presumed to have been married to Justinian II during his first reign (685–695) and to have either predeceased him or divorced him by the time of his second marriage to Theodora of Khazaria in 703.
