Images have now been released by Ukrainian officials of Donald Trump's brief meeting inside St Peter's with Volodymyr Zelensky.
As you can see it's very much an ad hoc meeting on chairs - and the two men look engrossed in deep conversation.
The picture comes from Andriy Yermak, head of Zelensky's office.
This picture of Trump and Zelensky locked in deep discussion inside St Peter's Basilica, minutes before Pope Francis's funeral was about to start, is destined to become one of the defining images of a momentous day.
We know from Zelensky's spokesman there are plans for the two leaders to meet again later, but two months after that tempestuous meeting at the Oval Office the symbolism of this moment is striking.
During his homily, Cardinal Giovanni Battista Re spoke of Pope Francis's incessant calls for peace. "'Build bridges, not walls' was an exhortation he repeated many times," said the cardinal.
As Trump bids to forge a peace deal with Russia and Ukraine, this conversation and a potential second meeting later today could be significant.
