I fell off the map this week – at least that was what it felt like when I learned that I’d been removed from the intercom list at my townhouse complex. It doesn’t sound like much – a simple omission when they were doing the complex list – but think about it. To the outside world I no longer existed in this location. I inhabited an invisible place outside of the normal world that happened to be located between the house number below me and the one above – much like the safe house in Harry Potter but without the overt magic. I was gone, and so was my home and all the mementos I’ve collected from across the world. And of course my cats.

I’ve experienced something similar before, when I worked in the interior of British Columbia in a small town that was a long ways away from anywhere. When my agency’s reporting relationship shifted from one region to another, all the paperwork connections seemed to disappear and no one contacted us – it was actually quite a nice change. But it was also like we inhabited some huge fog bank that filled a space in the center of the province that no one knew existed. Our own personal twilight zone.

Such phenomena isn’t only in my imagination. Cartographers have been erasing or omitting bits of the landscape from their maps since before Prince Henry, when choice harbors and trade routes were secrets worth killing for. In order to gain a truer picture of the world, it became common practice for Kings to confiscate the log books and charts of each ship that came to harbor in order to copy them down before the sailors took ship again.

During the time of the early Portuguese spice trade, the location of, the Moluccas, the five tiny islands that were the sole source of nutmeg, mace and cloves, were closely guarded secrets. True maps of the eastern Indian Ocean were treated as highly classified documents (and few exist today) due to the possibility that the Portuguese were violating a Papal bull which gave the Spanish sovereignty over all lands west of a longitudinal line running 100 leagues west of the Cape Verde Islands (in the Atlantic).

During the age of exploration and when Spain, France and England were vying for the Americas and the Northwest Passage, maps were made that purposely misrepresented the landscape in case they fell into (and sometimes purposely intended for) the enemies’ hands. Such maps were intended to deter exploration by competitor nations because the harbor, the river, the inhabitable, productive land wasn’t there.

Even today we see maps shift reality so that places exist differently than what you would find ‘if you were on the ground’. Road maps often include streets that are planned, but have never been built, or don’t describe that the street crossing that looks so direct on the map, can’t be made. A recent internet report showed that Chinese government maps of cities often change the position of major streets. Why? For military purposes. The government has apparently fallen back on the ancient practice of redrawing reality to stop potential invasion or intelligence gathering.

Happily, I’ve been replaced on the list of existing residents of my complex and so my home and I have been returned to reality. There is no longer a fog where my house once stood and my cats and I are all okay.
