| * Wrong meridian. A Cahill-style map, unlike here, divides
at 20º W, so as not to split Africa, Spain, UK, etc.. On this map,
no other layouts (N. Pacific or S. Atlantic, etc.) are possible without
splitting continents. Original caption: Gnomonic Octahedron; Polyhedral Globe; Platonic Solid; Source: John Parr Snyder’s Personal Software |
