An "original"<!--{{Nihongo|Origin|{{Ruby|原典|オリジン}}}}--> {{Nihongo|'''grimoire'''|魔道書|Madō-sho|lit. "Book of Magical Ways"|yenpress = '''ancient text'''}} refers to a book containing knowledge about [[magic]]. They are considered to be powerful tools with esoteric knowledge and powerful magic spells written in them.

It is harmful to all who dare read its contents, although, currently, only [[Index]] is immune to the debilitating effects of the grimoires, and with her perfect memory, allows her to serve as the vessel of the Index Librorum Prohibitorum. However, suspicions rise that she would rebel and become a [[Magic God]]. This suspicion marks the catalyst for the events that would lead to the beginning of ''Toaru Majutsu no Index''.

As stated, original grimoires are harmful as reading its contents would drive a human into insanity,<ref name=IndexV1Ch2Pt2>{{Qvl|Index|L|1}} Chapter 2 Part 2</ref> and are even harmful to those that are trained to handle them.<ref name=IndexCh4>{{Qcl|Index|4}}</ref>

According to Index, what is written inside of a grimoire is of a different world, and contradicts common sense, a knowledge that is far too alien to be safely comprehensible to any normal human.<ref name=IndexV1Ch2Pt2/> The knowledge that a grimoire possesses is "poisonous" in the sense that it is too "pure" for the human mind to handle and must be "watered down" - i.e. written in such a way that many of its meanings are obscured—in order for people to be able to read it without their minds being destroyed.<ref name=IndexV15Ch3Pt12>{{Qvl|Index|L|15}} Chapter 3 Part 12</ref> Once a human is stained with the poison that is the contents of a grimoire, even inquisitors cannot remove the poison from the mind even after five years of baptism.<ref name=IndexV1Ch2Pt2/>

===Types of grimoires===
[[File:Oriana Thomson - Shorthand, Water Symbol.jpg|thumb|250px|right|Oriana with one of her shorthand grimoires.]]
A grimoire doesn't have to be in the shape of a book, for example: [[Aztec Mythology|Aztec]] grimoires being written on animal skins<ref name=IndexV15Ch3Pt12/> and in stone tablets.<ref name=IndexV18Ch3Pt10>{{Qvl|Index|L|19}} Chapter 3 Part 10</ref>

[[Oriana Thompson]] has also written up a form of disposable grimoires comprising flashcards, which allows her to use many different kinds of magic. Its drawbacks include its inability to cast the same spell twice with the same flashcard, so she has to keep writing grimoires in order to move forward; and its instability makes it destroy itself after a few weeks at best, as such it is not exactly a true grimoire.<ref name=IndexV9Ch4Pt2>{{Qvl|Index|L|9}} Chapter 4 Part 2</ref>

===Abilities and Behavior===
A grimoire is practically "eternal" in the sense that it cannot be destroyed with current human methods (such as burning) and can only be sealed away. Original grimoires can apparently convert the words that are written inside their pages into magical code, which can be described as an semi-permanent [[Magic Circle|magic circle]] or spell. The grimoires use the small amounts of energy released by nature or life force as well as the weak [[magical energy]] released by humans, because of this attribute of acting like an semi-permanent magic circle, a grimoire can never be truly destroyed.<ref name=IndexV7Ch2Pt1>{{Qvl|Index|L|7}} Chapter 2 Part 1</ref> For example, a grimoire such as the [[Aztec Calendar Stone]] has an automatic [[Interception Spell]] that could defend against any type of attack.<ref name=IndexV15Ch3Pt12 />

Index states however, that since she is unable to use her life force to create mana (due to the restrictions on her made by the [[Necessarius]]), a grimoire manuscript that she writes down will not create such phenomenon, as such they can be destroyed, when normally a [[magician]] and even a normal human who releases magic energy through their life force when writing a magic will have this problem.<ref name=IndexV7Ch2Pt1 />

The structure of a grimoire is compared to that of a [[Magic Circle]], with [[Stiyl Magnus]] demonstrating how a magic circle written with words can end up having 2 or 3 additional lines surrounding the original circle, like sentences on a page.<ref name=IndexV9Ch2Pt9>{{Qvl|Index|L|9}} Chapter 2 Part 9</ref>

====Sentience====
Grimoires are seemingly sentient enough to disclose its contents to people who desire information from it. Grimoires can apparently identify whether someone was a "reader" or "not a reader", and have the tendency to cooperate with those who would propagate the information with their contents.<ref name=IndexV15Ch3Pt12 />

As such, a magician could trick the decision-making capabilities of the grimoire under the belief that they could act as an evangelist for its knowledge. Regardless of this, the contents of the grimoire is still dangerous to anyone who reads it and those who attempt to take control of the grimoire. It is currently unknown if a grimoire is aware that they are dangerous to people.<ref name=IndexV15Ch3Pt12 />

If the grimoire judges its current owner to be unsuitable, it will kill him/her and seek out the next one, as shown in [[Toaru Majutsu no Index Manga Volume 15|Volume 15]], when [[Etzali]] needed to protect [[Xochitl]] from her own grimoire<ref name=IndexV15Ch3Pt12 /> and in [[Toaru Majutsu no Index Manga Volume 19|Volume 19]], when a grimoire actually killed its wielder as he was inadvertently trying to prevent it's knowledge from being handed down.<ref name=IndexV19Ch3Pt10>{{Qvl|Index|L|19}} Chapter 3 Part 10</ref>

===Countermeasures===
One theoretical way to destroy a grimoire, according to [[Orsola Aquinas]], is to write data that will force it to destroy itself into it. However, it is unknown if someone has successfully managed this, as the writer still needs to see the pages of the grimoire to actually write down the code, and even a mere glimpse of a grimoire is already dangerous.<ref group=Notes>[[Etzali]] under the guise of [[Unabara Mitsuki]] catches a glimpse of a grimoire that has replaced [[Xochitl]]'s skin.</ref> [[Kamijou Touma]] also suggested the possibility that his [[Imagine Breaker]] would be able to fully destroy grimoires, although he has yet to make any attempt.<ref name=IndexV7Ch2Pt1/>

[[Aureolus Izzard]]'s job before he met Index was to write up vaccines that can destroy grimoires for the [[Roman Catholic Church]].<ref name=IndexV2Ch3Pt4>{{Qvl|Index|L|2}} Chapter 3 Part 4</ref> It is unknown if the writer of an original grimoire can destroy their own creations.

It should be noted that when a magician has been enough skill, they can read the contents of a Grimoire and not suffer from its contamination, one of this cases was Aureolus.<ref name=IndexV7Ch4Pt2>{{Qvl|Index|L|7}} Chapter 4 Part 2</ref>

Grimoires can be prevented from autonomously activating through the use of grimoire-shaped decoys arranged in a certain formation next to them to confuse their ability to recognize themselves. Grimoires try to indiscriminately spread their information, and blurring the line between what it views as itself and something else prevents the Grimoire from determining how far it should send its information into a subject, leaving it effectively spinning its wheels without accomplishing anything.<ref name=NecessariusSSCh2>[[Toaru Majutsu no Index SS: Necessarius Special Admission Test]] Chapter 2</ref>{{TrackTag106}}

===Politics===
Not unlike [[Saint]]{{TrackTag51}}s, grimoires carry a somewhat heavy political pull, with it containing powerful spells as well as being indestructible, because of these, grimoires are sealed in their respective holding places such as libraries and cannot normally be stolen.<ref name=IndexV1Ch2Pt2 />

Grimoires are also used by the organizations keeping them to promote themselves, as with the case with the [[Roman Catholic Church]] displaying the [[Book of the Law]] to the public.<ref group=Notes name=IndexV7Pr> The Book of the Law being displayed for the public was of course fake, to give the Roman Catholic Church an excuse to hunt down Orsola Aquinas who can [[decode]] the Book of the Law, and pin her death on the [[Amakusa-Style Remix of Church]].</ref><ref name=IndexV7>{{Qvl|Index|L|7}}</ref> Furthermore, a lost grimoire could spell turmoil between the [[Magic Cabal|magic organizations]], as what had occurred with [[Amakusa Christians]] being accused for stealing the Book of the Law, causing the [[Anglican Church]], Roman Catholic Church as well as the [[Knights of England]] to take action.<ref group=Notes name=IndexV7Pr /><ref name=IndexV7 />

[[File:Toaru_Majutsu_no_Index_E04_11m_34s.jpg|thumb|250px|The Magic Library: Index Librorum Prohibitorum, keeper of the grimoires.]]
As such, magic societies will not simply leak the contents of the grimoires they keep for no reason, one of those rare reasons were to allow Index of [[Necessarius]] to memorize the grimoires for the purpose of reverse-engineering and neutralizing them, and with the 103,000 grimoires inside Index, there is a possibility that all magic in the world can be neutralized. Because of her status as a magic library, Index is reviled by magic societies for knowing the knowledge of the grimoires, knowledge that can be used against those who originally owned the knowledge before Index came along.<ref name=IndexV1Ch2Pt2 /> As such, Index is being hunted by Magic Cabals, and is feared by her own church.

The two fought using their respective grimoires, with Tecpatl having taken measures to prevent contamination from his grimoire's knowledge. However not being willing to read or spread the grimoire's contents became his undoing, as when he was about to finish off Etzali, the latter transcribed some of the grimoire's text, leading the grimoire to recognize him as a more suitable wielder and turning its attack back on Tecpatl.<ref name=IndexV19>{{Qvl|Index|L|19}}</ref>

Since the grimoire in that case would likely have been written in [[Germany|German]], his subsequent discovery through handwriting and [[residual information]] that [[Melzabeth Grocery]] was not familiar with German proved to him that she was innocent and not involved with Citrinitas as he had previously suspected.<ref name=SouyakuV4Ch3Pt9>{{Qvl|Souyaku|L|4}} Chapter 3 Part 9</ref> In the aftermath of the events in [[Los Angeles]], during a conversation between [[Anna Sprengel]] and [[Aradia]], it was noted that the latter's name was that of a figure featured prominently in a famous [[witch]]craft grimoire.<ref name=SouyakuV4Ep>{{Qvl|Souyaku|L|4}} Epilogue</ref>

It is a wide-ranging, comparative study of mythology and religion, written by Scottish anthropologist {{W|James George Frazer|Sir James George Frazer}} (1854–1941). It was first published in two volumes in 1890; and the third edition, published 1906–15, comprised twelve volumes.

According to Index in [[Toaru Gakuen no Index]], the grimoire was an experiment that tried to classify magic into two categories, though apparently led to failure as there were exceptions in categorizing magic into two categories.

[[Westcott]] apparently described the Golden Bough as tasteless, like Italian Pizza and simple as a hot dog smothered in mustard. He mentioned how the simple flavor drew in the masses and the toxin of the letterpress copies gathered charisma around him without anyone noticing, speculating that Frazer wanted public acceptance. [[Samuel Liddell MacGregor Mathers|Mathers]]' comments suggest that the Golden Bough incorporates [[Hermetic]] principles.<ref name=ShinyakuV18Ch3Pt4>{{Qvl|Shinyaku|L|18}} Chapter 3 Part 4</ref>

The grimoires were comprised of Tarot cards produced through selected materials. A special charcoal made from red wine and iron oxide and kneaded erasers made from breadcrumbs were used to make the rough sketches on the paper base, chosen to apply symbols of flesh and blood to the card. These sketches were colored with pigments chosen based on the personal traits of the individual to be recreated, found in things like {{W|bibliomancy}}, and the cards were reinforced with a thin layer of the [[Wax magic#Wax dolls|wax used for cursed dolls]].<ref name=ShinyakuV21Ch2Pt7/><ref name=ShinyakuV21Ch3Pt1/><ref name=ShinyakuV21Ch3Pt3>{{Qvl|Shinyaku|L|21}} Chapter 3 Part 3</ref>

According to Index, it is a realy magic grimoire, camouflaged to look like a harmless [[fairy tale]]. She states there's actually no such person as 'Momotarou who was born from a peach.

In Eastern culture, there is mention of a fruit of Immortality. Of course, it's the peach that the Queen Mother is protecting.
