Finally the globe is covered with the paper gores upon which the map is drawn.
The adaption of these gores to the curvature of the sphere calls for great care.
Generally from to 24 gores and two small segments for the polar regions printed on vellum paper are used for each globe.
The method of preparing these gores was originally found empirically, but since the days of Albert Darer it has also engaged the minds of many mathematicians, foremost among whom was Professor A.
Globes were still engraved on copper, or painted by hand, but since 1507, in which year Waldseemuller published a small globe of a diameter of 110 mm., covered with printed segments or gores, this cheap and expeditious method has come into general use.
