Theophanes the Confessor
The ancient Christian tradition of the Church fathers, as well as pilgrims to the Holy Land during the Roman-Byzantine period, unanimously recognized Nicopolis as the Emmaus in the Gospel of Luke (Origen (presumably), Eusebius of Caesarea, St. Jerome, Hesychius of Jerusalem, Theophanes the Confessor, Sozomen, Theodosius, etc.).
