The blockbuster matchup of world number one and two, the champions of each hemisphere, lived up to the hype.
Furlong was instrumental in the win over the All Blacks in Chicago, but took his game to another level at the Aviva Stadium, and was a real highlight, despite the fact that Ireland couldn't get the result.
Trips to Dublin have invariably ended in victory for New Zealand, which has restricted Ireland to single figures on 10 of its past 15 visits.
"I'm 100% an All Black supporter when they're playing anyone but us, just because that's where my roots are", he said.
He brushed past the surprised All Blacks, regathered and slid in from five meters out. We're going to be right up in that area.
Barrett closed the gap to seven points with his third penalty but Ireland saw the game out, keeping the world's best pinned back in their own half and claiming a second famous victory in two years. He was then replaced, with 17 minutes to go, and walked off to a standing ovation. Beauden Barrett offloaded to Ireland full-back Rob Kearney, and another attack died when a lineout throw was stolen by Ireland.
It was telling that Beauden Barrett opted successfully for the posts rather than the corner with his first opportunity in range, an option Sexton turned down nearly immediately after the visitors gave away their sixth penalty in just over 20 minutes.
Ireland initially looked to build on their lead, but soon found themselves forced onto the back foot as the All Blacks looked to click into gear.

The fire tragedy took place in Calabasas have had a huge impact on Khloé and her perspective of things has so drastically changed. As the Good American mogul had a big contraction, Tristan was seen at her bedside holding her hand.
Ireland loves to hog the ball, play phases, and kick for territory when moves stall. Ireland had seen this before, in 2013, when the All Blacks pulled a converted try out of their hat in injury time to win. The All Blacks are so tough to beat.
Elsewhwere, Michael Cheika praised his side's defence as the Wallabies recorded a 26-7 win over Italy in Padova.
At the same time, Hansen promised that his team would improve because of this defeat.
"We didn't want to let them over the line".
"The boys are very exhausted in there but it's wonderful what a win like that can do to give you a little bit more energy".
"This is out home and we haven't been beaten here in two years and we have pride in that".
"[It's] something we've been focusing on as a team to improve".
That was the decisive score, despite the visitors increasing the pressure midway through the half.
"We still had belief in ourselves to try and get across the line but it wasn't to be, so give them the credit".
