As map maker Plancius appears to have begun his activities shortly after taking up a residence in Amsterdam. His great world map in two hemispheres, one of his first productions, and one which may in part have served Blaeu and Hondius in the preparation of their masterpieces, of the years 1605 and 1611, respectively, was issued in the year 1592, a unique copy of which belongs to the Collegio del Corpus Christi of Valencia.[49] This map, bearing the title “Nova et exacta terrarum orbis tabula geographica ac hydrographica,” is composed of eighteen sheets, which, when joined, give a world map measuring 146 by 233 cm. Blundeville makes interesting reference to this map under the following caption: “A Plaine and full Description of Petrus Plancius his vniuersall Mappe, seruing both for Sea and Land, and by him lately put forth in the yeere of our Lord 1592. In which Mappe are set downe many more places, as well of both the Indies, as Afrique, together with their true Longitudes and Latitudes, than are to be found either in Mercator his Mappe, or in any other Moderne Mappe whatsoeuer: And this Mappe doth show what Riches, Power, or Commodities, as what kind of Beasts both wild and tame, what Plants, Fruits, or Mines any Region hath, and what kinds of Merchandize do come from euery Region. Also the diuers Qualities and Manners of the People, and to whom they are subiect. Also who be the most mightie and greatest Princes of the World: A Mappe meet to adorne the House of any Gentleman or Merchant, that delighteth in Geographie: and herewith this Booke is also meete to be bought, for that it plainely expoundeth euery thing contained in the said Mappe.”[50] Blundeville notes further that Plancius drew another map of the whole earth in two hemispheres, employing the polar projection. He does not give the date of this map, but it presumably was issued shortly after that of 1592. A Plancius world map in two hemispheres, bearing title “Orbis terrarum typus de integro multis in locis amendatus, auctore Petro Plancio 1594,” appears in the account of Linschoten’s expedition of 1599.[51] It is a well-drawn map, containing much valuable geographical data. Like Mercator, Hondius, and Blaeu, Plancius also undertook the construction of globes. Of these the oldest known appears to have been begun as early as the year 1612, the date appearing in the following dedication, “Nobilissimis Amplissimis Consultissimis ac Prudentissimis Dominis Consulariis Thalassiarchis atque Thalatto Oratoribus Hollandiae Zelandiae et Frisiae occidentalis nec non Magnificis ac Clarissimis Dominis Consulibus praeclarissimi Emporii Amstelodami, Petrus Kaerius humillimus cliens L. M. Q. dat, dicat, dedicat. Anno 1612.” “To the Most Noble, Exalted, Learned and Prudent Consular Lords and Orators Maritime of Holland, Zeeland and West Friesland, also to the Great and Distinguished Lords Counselors of the Renowned Emporium of Amsterdam, Peter Kaerius their humble client gives
