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.' The "Rogerio Greco" mentioned as a judge in 1441 cannot be identified with the supposed progenitor of the Paleologo Mastrogiovanni line since it would have been impossible for him to have been a judge at only 11 years old.' A 1489 census of San Mauro Cilento records no inhabitants with Byzantine surnames, though records a widow and daughter of "Quondam Princi de Rogerio Greco", someone subsequent censuses make clear left no further descendants. The presence of double-headed eagle symbols in the "Spirito Santo" church has been used as an argument in the past, but this symbol was not unique to the Palaiologoi, being used as a symbol by other families as well (both Byzantine and Western).
