The bearded face was discovered on the remains of a tree in Belfast City Cemetery, which was cut last week.
It has attracted local attention, and now the image has been captured on video and posted online by Belfast man Sean Osborne.
Mr Osborne went to the cemetery to investigate after his friend, who had been working in the area, spotted what he believed to be the Son of God’s face.
“Lots of people have been to see it and one woman has been there saying the rosary at the stump.
“It really is mounting in terms of curiosity,” he told UTV.
“You can feel the hair on the back of your neck stand up, you really need to see it for yourself.”
The tree was growing in the grave of a young girl called Rebecca Steven, who was buried in August 1916.
A Belfast City Council spokesperson said the image was uncovered during general tree maintenance.
“People have said there’s a likeness to Jesus Christ on the stump,” she added.
The council did not comment on how the image appeared, and Sean said he was not sure either.
“Being a sceptic I’ve been down and scrubbed at it, but you can’t really tell how it got to be there. But I put it on YouTube to let people make up their own mind.
“If someone has painted it on, they’ve done a really good job and kept quiet.
“I don’t really know what I saw, but it will be interesting to see how it pans out,” he explained.
