 In modern scholarship, Rogerio's existence is overwhelmingly dismissed as fantasy.The potential Palaiologan heir being kept as a hostage in Italy agrees poorly with contemporary Byzantine-Aragonese relations and importantly, no Byzantine historians mentions his existence.The contemporary historian George Sphrantzes, who described the life of Thomas Palaiologos in detail, wrote on the birth of Andreas Palaiologos on 17 January 1453 that the boy was "a continuator and heir" of the Palaiologan lineage, a phrase which makes little sense if Andreas was not Thomas's first-born son.'
