 Michael Fremaux, in support of the hypothesis that the Italian manuscript may have been brought to Amsterdam from Translyvania, instances Symon Budny, Jacob Palaeologus and Christian Francken as late 16th century anti-Trinitrian thinkers with Transylvanian connections, whose religious teachings find close parallels in the Gospel of Barnabas.Transylvania was nominally under Turkish overlordship and had close links to Istanbul; and when following the death of the anti-Trinitarian prince John Sigismund Zápolya in 1571 it became difficult for anti-Trinitarians to publish locally, attempts were made in the 1570s to establish a printing press in the Turkish capital to publish radical Protestant works.Following the conquest of Moorish Granada in 1492, Sephardi Jews and Muslim Mudéjar were expelled from Spain.
