At 48.8 degrees north, an invisible line crosses Paris.
No map really marks it, yet it runs from east to west above rooftops, stations, and bridges, quietly following the curve of the Seine.
One afternoon, I began to follow it.
At first, everything feels familiar: the Île de la Cité, the pale stone of the quays, a city that seems already aware of its own image. Then, almost imperceptibly, the city shifts.
A weathered poster of Johnny Hallyday watches the street. Beneath it, other faces appear, other layers of time.
That is where the city begins to reveal itself.
A figure enters the light and disappears.
Two walls covered in posters seem to recognize each other.
Nothing extraordinary happens.
And yet, along that line, another map of Paris appears—made not of monuments, but of encounters.
A city that exists only in this way: in fragments, one moment at a time.
