Following their team's emphatic triumph over the world and European champions, crowds spilled out onto the street and into a carnival atmosphere.
Clearly this story is not over, and there is much work to do; for now, however, football's primacy has been restored.
In fact there was much cause for optimism on the pitch.
This was a well-deserved win from a team that looks to be gaining in stature, and the atmosphere inside the Maracana for the final was profoundly imposing.
Of course Brazil won the 2009 Confederations Cup before limping out in the quarterfinals in South Africa; but this time they will be at home. The World Cup will be a tougher test; but don't bet against them.
4. Spain needs a re-boot
Finally, after a seemingly interminable period of dominance, Spain's champions look to have been found out. For clues as to how, it is hard to see beyond the Germans.
Italy really should have beaten the Spaniards after playing them off the park for significant chunks of their semi-final; Brazil's 3-0 defeat of the world champions was a muscular and ruthless final execution.
Both owed much to the approaches of Bayern Munich and Borussia Dortmund in their UEFA Champions League defeats of Barcelona and Real Madrid.
Spain were hustled and hassled, with attempts to impose their intricate passing game met by fiercely committed opponents, closing them down until the Europeans simply folded.
Fernando Torres only won the golden boot because of his goals against Tahiti's part-timers. Xavi and Iniesta are still fabulously creative, but elsewhere Spain's weak links were exploited with a kind of physicality this team now seems incapable of countering.
Drained of confidence, or possibly just appetite, they looked listless and in dire need of fresh ideas.
The sight of a defender, Sergio Ramos, taking a penalty that could have brought them back into the final spoke volumes.
True Brazil had had an extra's day of rest before the final, but the mask of invincibility has slipped; Spain has 12 months to work out how to set it back in place.
5. The Confederations Cup comes of age
In theory at least, the Confederations Cup is the unloved second cousin of the World Cup, the Euros and the Copa America.
Traditionally these games are seen by the cynics as little more than jumped up exhibition matches -- a mere aperitif before the main meal of the World Cup. By and large, no one really cares who wins.
This time, however, something seemed to click.
Maybe it was the location. Brazil may have some serious issues to confront, but there is something about the host country that elevated this tournament onto a different plane.
In football terms, this is about as educated as any crowd can get.
The enthusiastic way in which local fans adopted teams such as Japan, Uruguay, Tahiti and Italy conveyed atmosphere and meaning to fixtures where normally none would exist, and more than made up for the absence of traveling support.
The outcome, for the neutrals at least, was first class entertainment.
Brazil 2013 served up some of the most memorable international games of recent memory, played in front of passionate crowds in some spectacular arenas.
If Brazil 2014 can pick up where this rehearsal left off, then we are truly in for a treat.
