The map represents the world in two hemispheres, a northern and a southern, each drawn on thirty-six half gores or sectors. The following appears to have been the method of construction. With the poles as centers, and with a radius equal to one fourth of the length of a meridian circle of the globe he drew his large circle or circles representing the equator and forming the bases of each of the half gores. Each of the large or equatorial circles he divided into thirty-six equal arcs, and from the points establishing such divisions he drew a meridian line extending in each hemisphere to the pole or center of his circle. These meridian lines were graduated and lines or arcs representing parallels of latitude were drawn intersecting them at intervals of ten degrees, having the pole as the common center in each hemisphere. Marking off on each of these parallels or arcs both to right and left a distance representing five degrees of the earth’s longitude, he thus established the points through which to draw his meridians which marked the boundaries of each sector, leaving between the sectors equal spaces to be cut away should the sectors be used for pasting on the surface of a sphere. Every fifth meridian and every tenth parallel is drawn in black; the equator, the tropics, the polar circles, and the prime meridian are gilded. The prime meridian runs somewhat to the west of the Island of Fayal. At longitude 20 degrees west is the papal line of demarcation which is called “Meridianus particionis,” crossing South America south of the mouth of the Amazon. On the one side of this line in the southern hemisphere appears the flag of Spain, on the other that of Portugal, thus designating specifically the “Hemisperium Regis Castelle,” and the “Hemisperium Regis Portugalie.” California is referred to as “yᵃ q̄ descubrio el marq’s del valle,” “island discovered by the Marquis del Valle,” and the coast north of this point is called “ter̄a q̄ cnbio(?) a descubrio dē antᵒ d’ mēdoca,” “land to discover which Don Antonio de Mendoza sent out an expedition.” In drawing the outlines of his continents he seems to have made use of the best available sources. The New World follows the Sevillan type, as represented in the Ribeiro maps, particularly the eastern or Atlantic coast regions, including, though in somewhat abbreviated form, the references to Gomez, Ayllon, and Narvaez. There is no distinct coast line north of California, which line follows the meridian of 105 degrees as far north as the Arctic circle, hence there is no positive representation of an Asiatic connection, but rather the indication of a doubt, as was indicated on maps of the type. If Santa Cruz intended his peculiar gores to serve in the construction of a terrestrial globe, we cannot find that he impressed his method on the globe makers of the period. We seem to have but one striking imitation of his work, viz., in the gore map of Florianas, to which reference is made below.[260]
