As the first post-Columbian century came to its close the center of interest in great transoceanic exploration and discovery shifted to the northwest of Europe, to England, and to the Netherlands. Since expeditions were daily setting sail to all shores of the world, “Quoniam in omnes mundi plagas quotidie magis magisque navigatur,” quoting the word of the enthusiastic Hondius, the chart and globe makers found their services in great demand, globes both terrestrial and celestial being still regarded as essential to a navigator’s complete outfit of sailing instruments. The quick-witted Netherlanders, with well-developed business instincts, engravers, printers, map and globe makers, set to work to correct the old and to construct new “seamen’s cards” to serve the seafarers in their enterprises, and it was not long after entering this field of scientific endeavor that leadership by them was clearly attained. Although of Danish origin, perhaps logically the Van Langren family should have had first consideration in this chapter, since father and sons came to be loyal supporters of their new homeland’s interests, and it was in the Netherlands where were laid the scenes of their activities in the field here under consideration. Chronologically, however, they had place in the preceding chapter because their work as globe makers began in the early eighties of the sixteenth century. They, at least, be it said to their credit, led the way, achieving some of their highest successes in the early seventeenth century. This, too, was the time when the Hondius, the Blaeu, the Jansson, and the Goos families came to the front to contribute their part, in a very distinguished manner, toward the promotion of the work so ably begun by their contemporary, Jacobus Florentius van Langren.
