Blaeu has called especial attention to the four distinguished explorers who prior to the time of the issue of his map had circumnavigated the globe, placing their portraits in an elaborate cartouche south of South America and calling attention to their success in a somewhat elaborate legend. The four represented are “Ferdinandus Magallanes,” “Franciscus Dracus,” “Thomas Candish” and “Oliverus van der Nort,” the course of the latter being conspicuously traced on the map, his circumnavigation at this time attracting considerable attention, particularly in the Netherlands. The artistic adornment of Blaeu’s map is not its least attractive feature. Its elaborate border, so much of it at least as remains, there being evidence that at both top and bottom much has been cut away, alone gives it almost first place among the fine examples of copper engraving of the period. On the right and the left we find representations of “London,” “Hamburgh,” “Mexico,” “Cusco,” “Dantzik,” “Moskow,” “Bergen,” “Stockholm,” alternating with representations of typical people of the earth, such as “Groenlandi,” “Chilienses et Peruviani,” “Brasilienses,” “Moscovitae,” “Chinenses et Japonenses.” The “Rex Hispania,” “Imperator Romanorum,” “Imperator Turcarum” and “Rex Chinarum” appear in martial array and are given places of special prominence near the top of the map, while the “Rex Abissinorum,” “Rex Persearum,” “Magnus Cham Tartarorum” and “Magnus Dux Moscoviae” command in corresponding positions at the bottom. In his representations of the celestial hemispheres he gives special credit to Tycho Brahe and to Frederik Houtman for his information. Parallels and meridians are drawn at intervals of ten degrees, the prime meridian passing through the islands of “S. Michiel” and “S. Maria.” Compass roses are numerous, two of these being especially conspicuous by reason of the fact that with them appear the Dutch names of the thirty-two compass points or directions, and the radiating lines serve as loxodrome lines. No less than thirty ships are represented sailing the oceans in all parts of the world, carrying either the pennant of Spain, of Portugal, of Holland or of England. A few of these are curiously interesting, there having been an attempt to fashion them after the manner of the countries to which they belong, as, for example, a Japanese vessel off the coast of Japan, “Navis qua Japonenses utuntur quae illis Champan dicitur,” and an open boat in the Pacific near the Strait of Magellan, “Huiusmodi navicularunt forma freti magellaniei accolis in usu est.” Sea monsters are numerous, and Neptune is represented in certain parts carrying either a trident, a pennant of Spain or one of Portugal. Blaeu has not omitted the representation of numerous land animals thought to be native to the regions in which they appear, as in Africa the lion, the tiger, the elephant, the camel, the ostrich, the crocodile; in South America the llama, the alpaca, the monkey, the
