"I would not want you to falsely imagine that seeing the Antipodes, where I am now taking you, would cost us a journey of at least eleven thousand miles, which is the distance from here to the opposite side of the world. This is quite the opposite of the truth; indeed, the way to never reach them is to go there, and the reason for this is very clear: because there are no Antipodes, except [opposite] feet against feet; nor can they be [opposed] except on the points of the earth's diameter: therefore we must be half a world away. (Part I, Chapter XIX, “'The Antipodes”'; 1664, p. 295)"
