on the two globes the outlines of the New World are almost identical. As to the date when constructed, a comparison with other globes of the second decade of the century has led to the conclusion that it must have been prior to the year 1515, and perhaps as early as 1513. In its representation of the Old World, the land is made to extend through 240 degrees, counting from the island of Porto Santo, whose meridian has been taken as the prime meridian. The northern section of the New World is given the name “Par(ias),” the last letters of the word having been obliterated by age, while the southern section is called “America.” The great austral land south of the apex of the southern continent, appearing on the Schöner globe of 1515 as “Brasilie regio,” is omitted on the Hauslab globe. The continents, rivers, and mountains represented are very dark in color, and were probably originally blue, black, or red, and the seas are a dark blue. The equator, as drawn on the surface of the sphere, is divided into degrees, represented alternately in white and black, and every tenth degree is indicated by an appropriate number, beginning, as stated above, at the island of Porto Santo. By way of decoration a border of gold is given to the lines representing the equator, the tropics, and the polar circles.
