While going through a bunch of old books for another impending cross-country move, I found myself re-reading an interesting detail in The Colosseum by Keith Hopkins and Mary Beard.
In a discussion of that ruined megastructure, now symbolic of the entirety of ancient Rome, Hopkins and Beard point out that the colosseum was once home to a rather unexpected ecosystem, a displaced environment that did not correspond to the natural world outside its crumbling walls.
“For whatever reason—because of the extraordinary micro-climate within its walls,” they write, “or, as some thought more fancifully, because of the seeds that fell out of the fur of the exotic animals displayed in the ancient arena—an enormous range of plants, including some extraordinary rarities, thrived for centuries in the building ruins.”
The idea of entire landscapes, even alien ecologies populated with otherwise unrecognizable species, lying hidden in the fur of exotic animals, gradually encouraged to flourish by the weird winds of an architecturally induced micro-climate, is absolutely fascinating to contemplate. You could think of them as animal ballast gardens, stuck like burrs on the unseen surfaces of the everyday world, waiting to prosper.
The Anthropocene is much older than today’s conversations seem able to admit; it began in patches, sprouting here and there in the broken stones of old buildings, transported across continents one seed at a time until the entire planet now is ablaze with artificial landscapes, a planet out of joint.
