In this critical review of G.D. Martzelos, Origin and Sources of the Definition of Chalcedon (in Greek ; Thessaloniki, 1986), the present author shows : (i) that the letter of Cyril with the Twelve Anathemas against Nestorius was given no canonical authority by the Fathers of the Fourth Ecumenical Council ; (ii) that any essay at reconstructing the text of the lost draft of the Definition is
