Amid the fast-paced traffic of Manaus, in Amazonas, Brazil, there's a point where meaning dissolves.
Seen from above, the image appears to show a roundabout like any other.
But in its centre rests an unusual sculpture: gigantic steel letters intertwined in a knot.
Created by artist Sérgio Cardoso in 2003, the work arrived before the roundabout itself—traffic circled around it before any road planning.
Made of stainless steel and about 4 metres tall, its original name, 'Diálogo,' never stuck.
For residents, it was always 'Bola das Letras.'
And so, it remained: a spontaneous nickname, a reference that slipped out of control and became part of the urban landscape.
Today, few remember the official title—or even the name of the roundabout.
