We do not see a sufficient basis for maintaining the vision of Professor Settipani, the mutual relationships of the persons are more important that the birth years are correct. Prof. dr. Settipani is the recognized specialist on the genealogy of Charlemagne and with that knowledge he also has a view on the ancient Byzantine genealogy history.
