Initiatory paths in Christian gnosis: the mosaic floor of Aquileia and the Pistis Sophia

Was original Christianity, Judeo-Christianity or Essene-Christianity, that doctrine that Christ handed over to his "pneumatic brother" James, a teaching that RenΓ© GuΓ©non saw impenetrably wrapped in the most discreet reserve, was it a gnosis? We can answer affirmatively by examining the representations of the large mosaic carpet inspired by Judeo-Christian themes present in the cathedral of Aquileia. Their peculiar iconography provides much more than a clue to support this thesis.
