In the matter of geographical record terrestrial globe maps stand with the plane maps of the same period. While they are by no means as numerous as the plane maps, there attaches to them an importance no less historically significant. Not infrequently they give us records not to be found elsewhere. In their general features, differences can hardly be said to exist between plane maps and globe maps. In the matter of adornment there is similarity; each following the practice of the time when constructed. As pictures and legends hold a place of prominence, particularly on mediaeval maps,[201] so even to the close of the period we have had under consideration, that is, the end of the eighteenth century, these adornments have place on globe maps, sometimes few, sometimes many, the same, if in picture, exhibiting the inhabitants of land and sea, if merely a legend, giving information of geographical importance on the terrestrial globe and of astronomical importance on the celestial, these legends being often placed in an artistic cartouch. To the printed or engraved globe map, color was generally added by hand with an effect often very artistic, in contrast with which the modern machine methods of color printing are deplorably crude. On most terrestrial globe maps meridian circles are represented at intervals of ten, twenty, or thirty degrees, the prime meridian on which the degrees of latitude are marked being usually made very conspicuous, and to the close of the period under consideration usually made to pass through the Cape Verde Islands or the Canaries, a point always to be carefully noted in attempting to get a reading for the longitude of any particular place. Parallels are usually drawn at intervals similar to those of meridians, the equator on which the degrees of longitude are marked, the tropics, and the polar circles being always conspicuous. The ecliptic or zodiac is usually indicated encircling the globe from the solstitial point on the tropics, intersecting the equator at the two opposite equinoctial points, through which as through the solstitial points the colures are made to pass. Hues states that “Those lines which a ship, following the direction of the Magnetic Needle, describeth on the surface of the Sea, Petrus Nonius calleth in the Latin Rumbos, borrowing the appellation of his Countrymen the Portugals; which word, since it is now generally received by learned writers to express them by, we also will use the same,” that is, rhumbs or rhumb-lines.
