Leontius of Byzantium and His “Theory of Graphs” against John Philoponus
P. 143–170.
Lourié B.
The main project of Philoponus on the eve of 553 was a reinterpretation of the Chalcedonian “unique hypostasis” as a particular nature, which would open the way to allow the official Church under Justinian to adopt the basic assumptions of Severian Christology. We see the Chalcedonian position that there is no such thing as a particular nature which is not identical to the hypostasis staggered precisely in the middle of the sixth century. This is the historical context in which Leontius’ change of mind would seem most natural – especially if he did really keep his Origenistic skeleton in the closet.
