Cornelio Desimoni, the archivist of Genoa, has printed two elaborate papers.[720] The Danish archivist Frederik Krarup published (1878) a sceptical paper in the _Geografisk Tidsskrift_ (ii. 145).[721] The most exhaustive examination, however, has come from a practical navigator, the Baron A. E. Nordenskjöld, who in working up the results of his own Arctic explorations was easily led into the intricacies of the Zeno controversy. The results which he reaches are that the Zeni narratives are substantially true; that there was no published material in 1558 which could have furnished so nearly an accurate account of the actual condition of those northern waters; that the map which Zahrtmann saw in the University library at Copenhagen, and which he represented to be an original from which the young Zeno of 1558 made his pretended original, was in reality nothing but the Donis map in the Ptolemy of 1482, while the Zeno map is much more like the map of the north made by Claudius Clavis in 1427, which was discovered by Nordenskjöld in a codex of Ptolemy at Nancy.[722] * * * * * Since Nordenskjöld advanced his views there have been two other examinations: the one by Professor Japetus Steenstrup of Copenhagen,[723] and the other by the secretary of the Danish Geographical Society, Professor Ed. Erslef, who offered some new illustrations in his _Nye Oplysninger om Broedrene Zenis Rejser_ (Copenhagen, 1885).[724] Among those who accept the narratives there is no general agreement in identifying the principal geographical points of the Zeno map. The main dispute is upon Frislanda, the island where the Zeni were wrecked. That it was Iceland has been maintained by Admiral Irminger,[725] and Steenstrup (who finds, however, the text not to agree with the map), while the map accompanying the _Studi biografici e bibliografici sulla storia della geografia in Italia_ (Rome, 1882) traces the route of the Zeni from Iceland to Greenland, under 70° of latitude. On the other hand, Major has contended for the Faröe islands, arguing that while the engraved Zeno map shows a single large island, it might have been an archipelago in the original, with outlines run together by the obscurities of its dilapidation, and that the Faröes by their preserved names and by their position correspond best with the Frislanda of the Zeni.[726] Major’s views have been adopted by most later writers, perhaps, and a similar identification had earlier been made by Lelewel,[727] Kohl,[728] and others.
