It's said that journalism is the first draft of history.
But there's little doubt that the history created at Lagoa stadium in Rio de Janeiro today will not need much revision as the decades and centuries roll on.
Eric Murray and Hamish Bond, by winning their second Olympics gold medal in the men's pair, have cemented themselves among not just New Zealand sporting greats, but among the elite all-time athletes of the world.
Think about the numbers. They came out of the four that couldn't make the Beijing Olympics final in 2008 after starting the regatta as world champions.
Bond and Murray were identified as the powerhouses of that four, so they started as a pair under the coaching of the legendary, but very grumpy, Dick Tonks. That was 2009.
So two Olympic golds later, alongside six world championships and a 69 race unbeaten streak, who can find a better crew in the history of rowing?
Yet a bit of time in their presence today suggests that they are not exactly peas in a pod.
On the contrary, they are the complete contrast in personality.
Eric is the gregarious, talk-with-anybody type, happy to pose for photos with whoever wants one, and looking for a good night of celebrating at the New Zealand club in Rio.
Hamish, much quieter and more introverted, spent a fair amount of time around the New Zealand club fulfilling his numerous media obligations, before slipping away with his family.
One of whom, his brother Alistair, was part of the lightweight four which rowed their final only an hour after the pair's triumphant race.
Without knowing either of them very well, you get the feeling that their out of the boat relationship might be a bit like Mick Jagger and Charlie Watts - they work together but don't play after hours that often.
But whatever their individual personality traits, their combination is one of the all time global sporting greats.
Can anyone name any individual or team, competing in elite international sport anywhere in the world, who has gone seven years without defeat?
Think of the great stars of the last 50 years.
Even Jack Nicklaus, Pete Sampras, Roger Federer, Nikki Lauda, Michael Schumacher, Michael Phelps and Usain Bolt had days when others were better.
But in 69 races over seven years nobody has beaten Bond and Murray.
In fact nobody has even tied with them.
They've won every time they've gone to the starting dock.
To top that, they've joined a really select group of New Zealanders to defend an Olympic title.
So they're in the same chapter as Peter Snell, Mark Todd, Ian Fergusson and the Evers-Swindell twins. It's quite the galaxy of sporting stars.
Eric Murray and Hamish Bond are today among the most shining of stars.Their glow is sure to last for a very long time.
