RIO DE JANEIRO, Brazil (AFP) — Rio’s Sambodromo parades are a fantasy of beautiful bodies and dreamlike costumes, but the self-declared ‘Greatest show on Earth’ is prepared in a dirty street next to an open sewer.

The contrast between what happens inside Rio de Janeiro’s specially built samba stadium and just outside encapsulates the confounding, often tragic contradictions of Brazil.

Inside, watched by 70,000 paying fans, the samba schools marched all night Monday into Tuesday, in a stunning blend of military precision, wild imagination, and sexual energy.

Thousands upon thousands of performers turned the runway into a river of sequins, feathers, physics-defying floats, g-strings, and flesh oiled up to shine in the bright lights.

Only minutes before though, these same dancers had been standing around in a filthy, poorly lit stretch of Avenida Presidente Vargas, which runs alongside one of Rio’s many dead waterways, stagnant with raw sewage and other pollution.

“In the Sambodromo, it’s a dream, and that’s the whole point,” said Georgina de Oliveira, a 62-year-old maid, as she waited in a long line for a fetid portable toilet on the avenue. “But here we’re in reality. Here, it’s not a dream.”

BEAUTY AND THE BEAST

Avenida Presidente Vargas is where each samba school gathers its approximately 3,500 performers before parading. Final assembly is done to floats, costumes are donned, make-up put on and each wing of dancers and drummers marshalled into position.

The avenue is drab and lined with graffiti. An imposing building, once a teaching hospital, sits abandoned and partly gutted, the faded sign at the entrance still reading: “Serving the community.”

During the days of carnival, the street is temporarily transformed, thronged with bizarre costumes, and pulsating with joyful music.

Late Sunday, African warriors came running by, a section of men dressed as knives and forks shuffled to the side, and three leggy women fiddled with their tiny, sparkling substitutes for underwear. An enormous man dressed as an emperor of some kind scrolled through his cellphone.

Behind the performers, many of whom sat on the ground alongside their ungainly costumes, waited the crazy floats — a seahorse as big as a bus, a herd of golden camels, an entire Arab palace.

It would have been momentarily easy to forget reality if it hadn’t been for the combined smell of the canal, the portable toilets and gutters filled with urine and beer.

SILVER LININGS

City authorities say that carnival brings about US$1 billion in extra revenue to Rio.

That wealth clearly doesn’t go toward facilities for the Sambodromo’s makeshift backstage, let alone installing a sewage system in neighbourhoods around the stadium.

Still, a little wealth trickles down to the poor.

Jonathan Torres Ribeira, who says he’s been collecting aluminum cans from the street since he was a child, does well at parade time.

The revelers litter Avenida Presidente Vargas with beer and Coke cans, so the 23-year-old soon fills a large plastic bag. With 24 hours’ work, he says, he’ll make about 500 reais (US$160) — 10 times more than he would on a normal day.

The main difficulty? Hauling that bag through all the people dressed as sun gods, vegetables, fish and the like.

“It’s really hard to get through,” he said.

Just on the far bank of the stinking canal, free seats are available for people who want to watch the samba schools set off down the avenue before turning into the Sambodromo.

Elaine Pereira da Costa, 60, shook her head sadly when asked how the same city could feature such splendour and squalor within touching distance of each other.

“The Government just wants its money and that’s the end of the story,” she said, echoing most Brazilians’ contempt for their corruption-riddled leaders. “They could see you standing here, holding your nose and they wouldn’t care.”

But when the Uniao da Ilha samba school, which had been prepping for hours on Avenida Presidente Vargas, suddenly started moving, da Costa’s expression changed.

“Look how beautiful it is,” she said to her sister-in-law as a legion of people in butterfly costumes set off in perfect synchronisation. “Mother of God, how beautiful it is.”
