Lucius Ampelius, Liber Memorialis, II or IV century: "The globe of Earth, which is under the sky, is divided into four areas. One part of it is that which we inhabit; another is opposite to this and those who inhabit it are called anticthones; the two of these areas below are located opposite these and the people who inhabit them are called antipodes".
