The floating footprints of Mexico & Antimexico: "We have lost them. No one listened to those early conversations -- not even an idle snapshot survives. They walked till that winter hid them and it seemed the cruel Channel itself would freeze over, and no one, none of us, could ever completely find them again. Their footprints filled with ice, and a little later were taken out to sea."

Thomas Pynchon, Gravity's Rainbow
