The aim of this paper is to investigate the transfer of the name of ancient Pannonia from ancient sources, via the humanists’ writings, to the modern times. The research is based on the writings of four distinguished humanists whose work covered the region: Ransanus, Bonfini, Olahus and Gregoriancz. Taking into account preceding findings of the most distinguished expert on renaissance geography of Pannonia, Peter Kulcsár, the paper attempts to offer a possibility for identification of an author, whom Ransanus had employed in his work on Pannonia. The paper shows how these humanist writers copied from a variety of ancient sources, as well as from their immediate predecessors. It also points out how this reconstructed image of Pannonia from ancient sources and near contemporaries was sometimes used in a political context, reminiscent of discourses on the imagological ‘other’, common in the understanding the image of a region in the modern period.
