Dumbledore is Death is a Harry Potter fan theory, which suggests that Albus Dumbledore is the personification of Death described in The Tale of the Three Brothers. The three brothers are also represented by Voldemort, Snape and Harry.
The Tale of the Three brothers tells the story of the three Peverell brothers who find themselves facing a incarnate of Death in after they try to cross a river. Rather simply claiming their lives as his own, Death toys with them, offering them each a wish that he will grant.
The first brother, believing himself to be the greatest wizard of them all, asks for the most powerful wand in all the land, better known as the Elder Wand; the second brother, having lost his intended, asked for the ability to bring the dead back to life, so he was given the Resurrection Stone; and the third brother, a humble man, simply asked to walk through life without the fear of Death following him, and so he was given an Invisibility Cloak. In wizarding lore, these three objects became legendary artifacts known as the Deathly Hallows.
Voldemort, Snape and HarryEdit
Voldemort is similar to Antioch Peverell as they are both obsessed with power and wanted to conquer death. They also both aquired the Elder Wand in their lifetimes. While, Cadmus is represented by Snape as both were in love with a woman who died too soon. The last brother is similar to Harry, as they were gifted the invisibility cloak.
Just like Death with Cadmus and Antioch, Dumbledore played a role in the deaths of Snape and Voldemort. He also gave Harry the invisibility cloak. And like Ignotus, Harry “willingly” walked to Dumbledore on Platform 9 3/4 at King’s Cross and greeted Dumbledore. He greeted Death, his “old friend,” as is written in the Tale of the Three Brothers.
Behind the ScenesEdit
When asked on Twitter what her favourite fan theory was, J.K. Rowling responded that it was the Dumbledore as Death theory. Though, J.K. Rowling hasn't confirmed or denied the theory as being true.
