The 32-year-old Spaniard had wrapped up his 17th major, taken his career earnings beyond the $100 million mark and extended his record in Paris to 86 wins and just two defeats, AFP reported.
It also intensified the headache facing tennis' highly-rated but woefully under-performing next generation.
How do you solve a problem like Nadal? Or Roger Federer or Novak Djokovic and Andy Murray for that matter?
Since Nadal won his first major at Roland Garros in 2005, the 'Big Four' have claimed 48 of the past 53 Grand Slam titles.
In their careers, 36-year-old Federer has 20 majors, Nadal 17, Djokovic 12 and Murray three.
Nadal's victory on Sunday meant that the last seven Slams have been shared between players who are 30 and over.
Furthermore, world number one Nadal has a record 32 Masters 1000 titles, Djokovic 30, Federer, 27, and Murray 14.
Such is their dominance that former world number one Marat Safin, a two-time major winner, told reporters at the French Open that he would not be surprised to see Nadal and Federer "play until they are 40".
Nadal has not put a time limit on how much longer he intends to keep playing, no doubt wary of the ravages of his injury-hit career which have forced him to sit out nine Slams to rest either his knees or wrists.
"I am 32. That's how I feel. You can't fight against the age and you can't fight against the watch. The watch keep going always," he said.
"I am just trying to keep enjoying, and I am going to keep playing until my body resists, and my happiness is still high playing tennis.
"When that changes, that will be a time to do another thing – I am not worried about this."
Those who should be worried are the likes of world number three Alexander Zverev, who again flattered to deceive in Paris.
The 21-year-old made the quarterfinals of a Slam for the first time having arrived at Roland Garros with titles in Munich and Madrid and a runner-up spot to Nadal in Rome.
The German, however, struggled through three successive five-set matches before being trounced by Dominic Thiem.
"There is a lot of talk of me not being able to play five sets, not being able to play long matches. I think I have showed that I can this week," insisted Zverev.
"I think everybody can stop talking about it now."
Thiem, who is 24, showed flashes of resistance in the final before crumbling to a straight-sets defeat to Nadal in what was his first title match at the majors.
"It's a big goal for me to play soon another Slam finals," said the Austrian, the only man to have defeated Nadal on clay in the last two years.
"Of course it's going to be easier because it's not going to be the first time anymore. Then hopefully I can do it better than today."
Outside of Paris, where he also reached the semifinals in 2016 and 2017, Thiem has not progressed past the fourth round at any of the other three Slams.
Meanwhile, victory on Sunday meant that Nadal became just the fourth man of the modern era to win three or more Grand Slam titles after turning 30, joining Federer, Rod Laver and Ken Rosewall.
Australia's Rosewall presented the trophy to the Spaniard, 50 years after he won the title in Paris.
"I'm just glad I'm not playing today," said Rosewall in a nod to the raw power of Nadal.
