This might be evidence of a flub in filmmaking or an issue with continuity, but before the infamous crucifix scene involving Regan, it's easy to see the crucifix located elsewhere in the house. Christians and all people need to know that Ouija boards are not a gateway to communicating with dead loved ones. Ouija boards are direct communication with Satan and his demons only. When a person passes away, they can no longer communicate with the living (Luke 16:19-31)."

Although Pazuzu was considered to be evil, he was not evil incarnate. Pazuzu was regularly seen as a protective force as much as a destructive one, and he was invoked for protection from other demons — in particular, protecting pregnant women and children from the demoness Lamashtu, who was said to viciously murder young and unborn children. On one Lamastu amulet, a scene shows Pazuzu chasing the demoness away from her victim, [12] while another displays him destroying it. [21] Pazuzu is often depicted as a combination of animal and human parts with his right hand pointing upwards and his left hand downwards.Jason Rodriguez is a guides writer. Most of his work can be found on PC Invasion (around 3,400+ published articles). He's also written for IGN, GameSpot, Polygon, TechRaptor, Gameskinny, and more. Wiggermann, Frans (2007-01-01). "The Four Winds and the Origins of Pazuzu". Academia.edu . Retrieved 2022-03-26. Images of Pazuzu are similar to those of other Mesopotamian demons, but with some distinct characteristics. Pazuzu’s head takes on a more rectangular shape and features horns, heavy eyebrows, a two-pronged beard, and an open canine-like mouth displaying his teeth and tongue.

Perhaps the most famous modern Pazuzu is the demon who possesses a twelve-year-old girl in the 1973 horror classic The Exorcist. Of the two priests charged with exorcising the demon, one has encountered the same malevolent spirit before, while participating in an archaeological dig. Niederreiter, Zoltán (2018-01-06). "2017.

Retrieved 2022-03-26.In the first film, Linda Blair played Regan. Mercedes McCambridge provided the majority of Pazuzu's dialogue, most notably in all the scenes with Fathers Karras and Merrin. Pazuzu's voice is provided by Linda Blair herself in some early scenes, and Ron Faber in others. The face of Pazuzu is provided by Eileen Dietz, who also plays Regan during the vomiting, levitation and masturbation scenes. Pazuzu first appeared in William Peter Blatty's The Exorcist in 1971. [1] The novel is about a 12-year-old girl, Regan MacNeil, possessed by a demon. The demon is later revealed to be Pazuzu; though never explicitly stated to be the demon, two references were made about his statue, which was uncovered in the prologue by Father Lankester Merrin in northern Iraq. After Regan's mother worries about her daughter being possessed, Merrin and Karras arrive at her house and perform an exorcism on Regan and successfully force the demon out of Regan's body. In their struggle to free Regan from the thrall of Pazuzu, both priests perish. Ken Nordine was considered for the demon's voice, but William Friedkin thought it would be best not to use a man's voice. Pazuzu is known to us today largely due to The Exorcist, but the widespread prevalence of his iconography throughout the ancient world shows that even in his time, he was a well known and fairly popular demon. Pazuzu is also the only prominent Mesopotamian demon or deity to make its way into Hollywood films — and there may be several reasons for this. This last phase of development accords well with the new theology of a demonically populated underworld in the first millenium BCE. The change happens, moreover, at the same time as the advent of the practice of erecting in palaces and temples monumental statues and reliefs of magically protective beings, and of burying small clay images of them in the foundations.

Pazuzu first appears in ancient Babylonian texts as the King of the Winds, with the purpose of protecting mankind from hardships, other demons, and the more vulnerable, such as pregnant women and children. Pazuzu is often depicted as a combination of animal and human parts with his right hand pointing upwards and his left hand downwards. He has the body of a man, the head of a lion or dog, eagle-like taloned feet, two pairs of wings, a scorpion's tail, and a serpentine penis. The seven spirits in the second register, each with a different animal’s head, probably have a beneficial function: they seem to be symbolically guarding the door of the patient’s bedchamber. Once we learn the truth about Pazuzu’s purpose, Jony’s theory has legs. Was it in fact Pazuzu who forced the demons from young Regan’s body, and not the failed exorcisms by the two priests?The Exorcist III takes place 15 years after the original film. The film was adapted by Blatty from his novel Legion. Lieutenant Kinderman, who was also in the original film, has been on a murder case about mysterious deaths committed by an anonymous person. It is later found out that Pazuzu convinced the Gemini Killer, who died at the same time as Father Karras, to inhabit his body as punishment for saving Regan. However, as result of his suicide, his brain was severely damaged, which demons/spirits need when they possess a body. The Gemini Killer spent years stimulating his brain so he would be of use, and then began committing murders by possessing the bodies of the other inhabitants of the hospital where Karras had been staying. In the end of the movie after a turbulent exorcism is done, Karras regains control of the body and asks Kinderman to kill him, which he does by shooting him in the head, keeping him from being possessed again. A balanced phase, in the Old Babylonian Period, when cylinder seal designs often mix images (gods, symbols, and other motifs) of good and bad associations with respect to mankind. Lambert, Wilfred George (1970). "Inscribed Pazuzu Heads from Babylon". Forschungen und Berichte. 12: 41–T4. doi: 10.2307/3880639. JSTOR 3880639. Pazuzu is imagined as an especially frightening figure capable of scaring off any lesser demon or ghost.

The video’s presenter “Jony” maybe a tad over animated, however I feel his content is spot-on. The presenter offers an alternative theory as to why Pazuzu was seen as the possessing demon in the child Regan:
