Monster Items

Various monster items are seen in the basement of The Cabin, all of them serving as summoning artifacts to the Monsters to be used in The Ritual. The one eventually used by the five college students visiting the Cabin was Patience Buckner's diary, which has a string of Latin phrases that resurrected The Buckner Family as zombies.

All Monsters available to The Facility can be assumed to be associated with an item that will summon them, even real-world beings with no supernatural attributes such as human killers or wild animals. Only a small fraction are shown in the film, while more are referenced in the film's visual companion.

In horror movies, a particular item related to the antagonist is often featured prominently early on in order to hint at the nature of the threat and to foreshadow events to come. The sequence of the victims determining their own fate by choosing from among the monster items pays homage to this trope.

Inspiration
Monster-summoning artifacts are common in fiction, including books such as the Necronomicon from H. P. Lovecraft's mythos. In horror story convention, these items are often found in basements, cellars, and other hidden compartments of houses, where they are eventually found by the protagonists. In one of the main influences from The Cabin in the Woods, The Evil Dead, not only the Deadites are brought after reading from a cursed book, but the Necronomicon Ex-Mortis\Naturom Demonto is found in the abandoned cabin's basement.
