HARRY Potter is a bit of a British institution, packed with more magic and mystery than you can shake a wand at.
The series finished with The Deathly Hallows, named after the three most powerful magical objects in the Harry Potter universe.
Many of us – whether we’re fans of the series or not – will recognise the symbol for the Deathly Hallows: a triangle with a struck-through circle in it.
In the films, the symbol has been explained as representing the three objects which make up the Hallows: the invisibility cloak, resurrection stone and the Elder Wand.
However, the inspiration for this iconic insignia came from a place far darker, and far more real, than anyone would imagine.
An eerily similar icon appears in 1975 flick The Man Who Would be King, used to represent the Freemasons.
The Harry Potter creator explained that she was watching the film and drawing the character Professor Sprout when she received the call that her mother had died, and that something must have sunk in on a “subconscious level.”
In the doc, Harry Potter and the History of Magic, she says: “The Masonic symbol is very important in that movie.
“The reason I can be incredibly precise about when I drew this is that at some point when I was drawing the picture and watching the movie, my mother died.”
She said that she went on to re-watch the film, starring Sean Connery and Michael Caine, years later, and was stunned when she saw the Masonic symbol again.
Rowling adds: “I looked at the sign of the Deathly Hallows and realised how similar they are.
“I’ve got a feeling that on some deep subconscious level, they are connected.
“The Potter series is hugely about loss. If my mother hadn’t died, I think the stories would be utterly different and not what they are.”
