In Esmeralda, city of water, a network of canals and a network of streets span and intersect each other. To go from one place to another you have always the choice between land and boat: and since the shortest distance between two points in Esmeralda is not a straight line but a zigzag that ramifies in tortuous optional routes, the ways that open to each passerby are never two, but many, and they increase further for those who alternate a stretch by boat with one on dry land.
And so Esmeralda’s inhabitants are spared the boredom of following the same streets every day. And that is not all: the network of routes is not arranged on one level, but follows instead an up-and-down course of steps, landings, cambered bridges, hanging streets. Combining segments of the various routes, elevated or on ground level, each inhabitant can enjoy every day the pleasure of a new itinerary to reach the same places. The most fixed and calm lives in Esmeralda are spent without any repetition.
Secret and adventurous lives, here as elsewhere, are subject to greater restrictions. Esmeralda’s cats, thieves, illicit lovers move along higher, discontinuous ways, dropping from a rooftop to a balcony, following gutterings with acrobats’ steps. Below, the rats run in the darkness of the sewers, one behind the other’s tail, along with conspirators and smugglers: they peep out of manholes and drainpipes, they slip through double bottoms and ditches, from one hiding place to another they drag crusts of cheese, contraband goods, kegs of gunpowder, crossing the city’s compactness pierced by the spokes of underground passages.
A map of Esmeralda should include, marked in different colored inks, all these routes, solid and liquid, evident and hidden. It is more difficult to fix on the map the routes of the swallows, who cut the air over the roofs, dropping long invisible parabolas with their still wings, darting to gulp a mosquito, spiraling upward, grazing a pinnacle, dominating from every point of their airy paths all the points of the city.
