Gandalf's Mark on the Door

Gandalf's Mark on the Door is the decisive act that transforms Bilbo Baggins's quiet hobbit-hole into the rendezvous for Thorin Oakenshield's company of dwarves, launching the adventure that will carry him from the comfort of Bag-End to the dragon-haunted Lonely Mountain. By scratching a queer sign on the hobbit's beautiful green front-door with the spike of his staff, the wizard turns a polite refusal into an irrevocable commitment, binding Bilbo to a quest he never sought and marking him as the fourteenth member of the expedition.

The Mark and Its Meaning

After Bilbo Baggins, flustered by Gandalf's talk of adventures, scuttled inside his round green door and shut it, the wizard remained outside laughing long but quietly. Then he stepped up and, with the spike on his staff, scratched a queer sign on the hobbit's beautiful green front-door. This mark was the usual one in the burglar's trade, as Gloin later explained: "Burglar wants a good job, plenty of Excitement and reasonable Reward, that's how it is usually read." Gandalf had put it there himself, for very good reasons, as he told the dwarves when they questioned his choice of Bilbo. The sign served as a signal to the dwarves that the house was the correct meeting-place, and it also identified Bilbo as the burglar they had been promised.

The Mark's Consequences

The mark on the door directly caused the dwarves to arrive at Bag-End for the Unexpected Party. When Dwalin pushed inside as soon as the door was opened, he did so just as if he had been expected, and Balin, seeing Dwalin's green hood hanging up, remarked, "I see they have begun to arrive already." The sign was so convincing that Gloin, upon seeing the little fellow bobbing and puffing on the mat, had his doubts about Bilbo's suitability, but the mark itself was not questioned. Gandalf later scowled at Gloin and declared, "I put it there myself. For very good reasons. You asked me to find the fourteenth man for your expedition, and I chose Mr. Baggins." The mark thus overrode the dwarves' initial skepticism and established Bilbo's role before he had done anything to earn it.

The Mark's Removal and Legacy

The next day, when the dwarves and Gandalf arrived for tea, Gandalf knocked out the secret mark he had put there the morning before, making quite a dent on the beautiful door. The mark had served its purpose: the company was assembled, and the adventure was underway. Though the physical sign was gone, its effect endured. Bilbo, who had no signs on his door and insisted it had been painted a week ago, nevertheless found himself drawn into the quest, the Tookish side of his nature winning over the Baggins caution. The mark thus became the first of many thresholds Bilbo would cross, a literal and symbolic inscription of his new identity as burglar and adventurer, an identity he would grow into over the course of his journey.
