We all know the long, rich history of the Roman people, and the city's importance as the center of an empire, and thereafter as the center of the memory of that empire, whose echo, long after its end, still so defines Western concepts of power, authority and peace. What I intend to discuss instead is the geographic city, and how its shape and layers grew gradually and constantly, shaped by famous events, but also by the centuries you won't hear much about in a traditional history of the city. The different parts of Rome's past left their fingerprints on the city's shape in far more direct ways than one tends to realize, even from visiting and walking through the city. Rome's past shows not only in her monuments and ruins, but in the very layout of the streets themselves. Going age by age, I will attempt to show how the city's history and structure are one and the same, and how this real ancient city shows her past in a far more organic and structural way than what we tend invent when we concoct fictitious ancient capitals to populate fantasy worlds or imagined futures.
