In the elaborate dissertation on the works of John Blaeu, contained in the fourth volume of Clement’s “Bibliothèque Curieuse”, mention is made, at page 277, of an “Atlas Flamand de l’an 1662”. This is apparently a Dutch edition, to which reference is made by Lütke, under the title of “J. Blaeu’s Grooten Atlas, of Werelt Beschrijving, Erste Deel, ’t Amsterdam, 1662”. Beyond this reference, we know nothing of that edition. A German edition is also described by Brunet as announced in a catalogue of Blaeu’s; but it is not alluded to by Clement, nor can we find any other trace of it. If ever printed or in progress of printing, it may have been consumed in the great fire, by which, on the 22nd February, 1672, nearly all Blaeu’s stock in trade was destroyed. In part XII, pp. 20–23, of Levinus Hulsius’s Collection, is an extract from Linschoten’s Navigation, stating the progress of the Dutch in the attempt to find the passage, the discovery of which formed a favourite scheme of his countrymen at the end of the sixteenth and beginning of the seventeenth centuries. Summaries more or less concise, derived apparently from Blaeu’s abstract, the French “Recueil de Voyages au Nord”, or Adelung’s “Geschichte der Schiffahrten”, have also been given in most of the histories of Arctic discovery. Gerrit de Veer’s description of the second voyage, contained in the present volume, must be understood to relate almost exclusively to the proceedings of Barents’s vessel, as forming one of the fleet under Nai’s command. This reconciles or explains away such differences as may appear to exist between his narrative and that of Linschoten.
