So after the most eagerly-anticipated day in the trial so far, we adjourn for more tomorrow.
Mr Roux has tip-toed his client through his early life, his relationship with his mother, his challenges following the amputation of his lower legs shortly after birth, his sporting career and a number of other issues.
In particular, he detailed an intensely-felt fear of crime, going back to his childhood when his mother kept a gun in a padded case under her pillow.
And somewhat sensationally, he began his testimony with an extremely emotional apology to the family of his victim, girlfriend Reeva Steenkamp.
He battled through the words but maintains the night she died, when the model and law graduate had gone to bed, "she felt love.”
Pistorius looks drained after two hours of testimony. He will return to the witness stand in the morning.

On the back of that statement, Mr Roux asks Judge Masipa if the court might adjourn before he moves onto a new topic, and so we can start the day afresh tomorrow.
Judge Masipa asks Mr Nel on his view, and he says as long as it's not a daily occurrence he won't object.
The court has now adjourned to 9.30am Tuesday.
As soon as judge leaves, Pistorius sits down, puts his head in his hands.
His brother Carl goes over and wraps his arms around him. He is also being comforted by sister Aimee, and other family members.
He says he feels exhausted at the moment, and did not sleep last night: "lot of things going through my mind."
"The weight of this is extremely overbearing. It's alot to think about," says the runner.
Pistorius now detailing his religion: Anglican, and has been a devout Christian for many years.
His mother Sheila had been very involved in the church, singing in the choir.
His mother told him 'grow up knowing that God is our refuge.' When his mother died, he struggled with his faith.
Pistorius is becoming emotional again, saying Reeva was also very religious and prayed for him; says the couple prayed together.
"My God is my God of refuge," he tells the court, saying he has never needed his faith more than this past year.Back to top
He is asked about the broken window downstairs on his house, as shown in police photos during the state's case.
He said it broken by a cricket ball he threw for one of his dogs.
Pistorius says he has grown up with dogs, and had owned them before. He wanted them in part as guard dogs.

However, he said they are not aggressive at all. They licked police officers when they took crime scene photographs.
In December 2012, Pistorius says he was looking at properties to buy in Johannesburg, less than an hour's drive away. This was in part because it was where Ms Steenkamp lived: "I was bowled over by how much I felt for her."
In the meantime, he wanted to fix up a few things on his Pretoria home before he sold it.
Mr Roux is letting Pistorius talk and talk. He's giving plenty of detail about his brushes with crime.
Says on February 13 2013, hours before he shot and killed Ms Steenkamp, he was on the phone to his cousin warning him not to drive his new Golf GTi from Port Elizabeth to Pretoria because of hijack risk.
Pistorius says he made his base in Pretoria, choosing the Silver Woods Estate to buy a home in 2007.
"I chose that estate because it was further out of the city, it wasn't in the midst of everything," he said.
However, there was "constant development" on the estate and during that time "crimes were committed".
He moved in officially in 2008.
Now he is talking about 2012 in December when he was assaulted at a party after receiving threats.Back to top
The proseuction is likely to challenge many of these incidents as being a fabrication.
A police witness told the court Pistorius a search of the database revealed he has never reported being a victim of crime.
"I was returning from an interview, a made way for a car. When it passed me it slowed down, then I saw the muzzle flash," he says.
"Many people know where I live," he says, referring to his fame and public profile.
Pistorius explains he experienced many house break-ins when growing up, family members have been assaulted and car-jacked.
"One of my father's homes was ransacked. One of the burglars had cut his hand and wiped blood on the wall."
He claims his home was broken into in 2005, while he was in Manchester for the paralympic world cup. When he came back, a week and a half later, his TV had been stolen, and a laptop, and his car roof was cut.
Also claims he has been followed home late at night, and shot at on the highway.
With regard to drugs, he says he smoked marijuana after his mother died, as a teen, but nothing since. Only takes substances that are safe.
We now move onto his fears of crime - which, as mentioned earlier, will be a focal point of the defence case.
"Everyone in South Africa has been exposed to crime at some point," he said.
Pistorius says he gets "shy" about his prosthetic legs, and "embarrassed about them when I don't have them on."
Moving to a new topic, Mr Roux starts: "Mr Pistorius, let's talk about alcohol and drugs. Do you drink"
Pistorius says he does, but not when he's training which is for a substantial part of the year. And not to excess.
On the day of the boating accident, he had only consumed one drink but was not drunk. He drinks when away with family and friends around Christmas and New Year.Back to top
Pistorius is talking about the difficulties associated with competing away from home. He says it makes it hard on relationships with loved ones.
"Track and field athletes compete for five months a year away from home," he said.
Finding time to speak to family can be "difficult".
Pistorius is reminded he is still under oath, and the questioning resumes.
We're almost ready to resume here at the Pretoria HIgh Court.
Pistorius sitting hands clasped on his lap, staring forward, awaiting Judge Masipa.
Here is a more fulsome version of the apology given by Pistorius at the start of his testimony:
"I'd like to apologize and say that there's not a moment and there hasn't been a moment since, since this tragedy happened, that I haven't thought about your family.
"I wake up every morning and you're the first people I think of, the first people I pray for.
"I can't imagine the pain and the sorrow and the emptiness that I've caused you and your family.
"I was simply trying to protect Reeva. I can promise that when she went to bed that night she felt loved.
"I've tried to put my words on paper many, many times to write to you, but no words would ever suffice."
With that, we take the luncheon adjournment.
Pistorius family are all very red-eyed, hugging each other. It's been an emotional morning for them.
Ms Steenkamp leaves via a side-door. She has been having lunch inside the building, to avoid cameras.Back to top
