There were big welcomes for former South African president Thabo Mbeki, UN Secretary General Ban Ki Moon, Mandela's second wife Winnie, and jeers for current South African President Jacob Zuma.
For US President Barack Obama, there was outright rapture.

"It is hard to eulogise any man ... how much harder to do so for a giant of history, who moved a nation towards justice,'' Mr Obama told the crowd and a worldwide TV and internet audience.
The US president compared Mandela to Mahatma Gandhi, Martin Luther King Jr. and Abraham Lincoln and urged the world to act on Mandela's legacy by fighting inequality, poverty and racism. He said progress in the US and South Africa mustn't cloud the fact there's still work to be done.
Mr Obama called Mandela the last great liberator of the 21st century, and says he thinks about how to apply Mandela's lessons to himself as a man and as president.
"And while I will always fall short of Madiba's example, he makes me want to be a better man," Mr Obama said.
