Usain Bolt's legend is complete.
The sprinting megastar anchored Jamaica to 4x100m relay win in world record time on Saturday night at the London Olympics to accomplish the rarest of achievements.
Bolt has captured consecutive Olympic golden sprint trebles - winning the 100m, 200m and 4x100m relay titles at the London Games, as in Beijing four years ago.
The undoubted star of the Games is the only athlete to accomplish the feat.
The Jamaicans clocked an astonishing 36.84 seconds in the sprint relay on the final night of track and field in London - bettering their previous mark of 37.04s set last year.
"It's always a beautiful feeling to end off like this ... for me it is a wonderful feeling," Bolt said.
Bolt and Jamaica's victory followed a triumph for Somali-born British runner Mo Farah in the 5000m - a week after winning the 10,000m for his adopted nation.
But even though Farah's win sent the home crowd into raptures, he realised he was second fiddle to the Bolt show.
"What he does for the sport, it is absolutely amazing," Farah said.
"We take it for granted.
"We are not going to see a legend like him again."
And headline-grabbing Caster Semenya from South Africa managed a silver in her Olympic debut in the 800m final - three years after being forced to undergo gender tests.
Semenya was last for most of the race and sped up with 250 metres to go, but could not pass world champion Mariya Savinova of Russia, who took gold.
"Unfortunately I made a wrong move and it was too late to kick," she said.
"I am still young. If I focus on training hard I can achieve more."
Savinova's 800m victory capped a successful day for Russia, with Anna Chicherova snaring the gold medal in the women's high jump.
Russia also swept the gold medals in race walking - Sergei Kirdyapkin won the men's 50km walk, with Australia's Jared Tallent second, while Elena Lashmanova of Russia in the 20km women's race in a world record time.
Meanwhile, Brazil faltered in their bid to secure the only major football trophy missing from their cabinet - the Olympic gold.
Mexico downed the Brazilians 2-1 at Wembley to collect their first gold of the London Games.
But the Brazilians captured their second straight Olympic gold medal in women's volleyball while Norway took the gold medal in women's handball and Germany triumphed in the men's hockey final.
