''The Secret of Kells'' (original title) or ''Brendan and the Secret of Kells'' is an Irish/Belgian/French co-production directed by Tomm Moore at Creator/CartoonSaloon, the studio behind ''WesternAnimation/SkunkFu!''

A fictionalized version of the history of the ''[[http://en.wikipedia.org/wiki/Book_of_Kells Book of Kells]]'', the story focuses on Brendan, a young monk wanting to join his fellow monks in working on illuminating texts. But with the rising threat of [[HornyVikings Viking invasion]], his uncle, Abbot Cellach, is far more focused on fortifying the Abbey for the [[AStormIsComing inevitable attack]].

The arrival of Brother Aidan, a master illuminator from Iona, allows Brendan to finally have a teacher and gives him an opportunity to leave the Abbey's wall when he is asked to get materials for ink. Brother Aidan has [[HellFollowsWithMe fled the Viking onslaught]] and is the keeper of the [[IAmDyingPleaseTakeMyMacguffin legendary book of Iona]] -- the greatest work of illustration yet produced in Northern Europe, soon to be the Book of [[GeniusBonus Kells]]. Befriending an [[TheFairFolk enigmatic fairy]] named [[MeaningfulName Aisling]] in [[GhibliHills the forest]] and taking a part in assisting Aidan with the Chi Rho page, things go well for him until he encounters the evil Celtic god Crom Cruach, and the Viking threat continues to slowly move closer to the Abbey...

Praised for its gorgeous visuals and music (it even got a standing ovation from the staff at Creator/{{Pixar}}), it managed to surprise everyone and get a Best Animated Feature nomination at the Oscars in 2010. Cartoon Saloon's next feature, 2014's ''WesternAnimation/SongOfTheSea'', was also helmed by Moore and acts as the second part of an "[[ThematicSeries Irish Folklore Trilogy]]" which is to be completed with ''WesternAnimation/{{Wolfwalkers}}''.

The film is now up on [[http://www.hulu.com/watch/337397/the-secret-of-kells Hulu,]] meaning Americans can watch this gem for free.
!! ''The Secret of Kells'' provides examples of the following tropes:

* AdultFear: The third act. Because the young protagonist Brendan has once again disobeyed his uncle's (the abbot of Kells) strict curfews, he locks him and Aidan in the scriptorium, both out of anger and to keep them out of reach of [[spoiler:the invading northmen]]. In the ensuing [[spoiler:slaughter]], the abbot has a very sudden and positive character change when he is horrified to see all his schemes and preventive measures against [[spoiler:an invasion going up in smoke. He himself is wounded repeatedly and badly, and passes out. The scriptorium is set on fire. Unbeknownst to him, Brendan and Aidan managed to escape beforehand. They, in return, see the abbot lying in the snow and think he's dead]]. Now, Brendan believes the abbot, the only parent and relative he had ever known,[[spoiler: is dead, ]]while the abbot thinks that Brendan, his only surviving relative whose own life he risked to save him as a baby, [[spoiler:has burned to death because ''he himself had locked him there in the first place''. The movie ends very much with a very dark BitterSweetEnding as this misunderstanding is cleared up ''decades'' later. But still, the fears of an adult authority to fail in really ''really'' trying to protect his community and his nephew's life are fully and conveniently exploited in this film]].
* AllThatGlitters: The Book of Kells, especially for the Norse. Possibly the film's {{Aesop}}.
* AllThereInTheManual: Brendan and Aisling's backstories are revealed in the graphic novel adaptations of the film, written and drawn by Tomm Moore. The two stories are included as an insert with the Blu-Ray edition of the film.
%%* AmericanKirbyIsHardcore: The poster art seen above is... a little misleading. %% Zero Context. Referring to page images is not context.
* AnnoyingArrows: Averted. A single arrow to the shoulder is enough to grievously injure [[spoiler:Abbot Cellach]] but he manages to get back up and continue through sheer force of will.
* ArbitrarySkepticism:
** At their first meeting, Brendan correctly recognizes that Aisling is a "fairy". When Aisling later warns Brendan of Crom Cruach, he dismisses it as "pagan nonsense". The irony that lies in saying that to a fairy escapes him. Possibly justified in that, living most of his life at an Abbey, he can accept a minor supernatural being like a fairy, but cannot accept a being that is supposed to be a ''god'', when in his mind there is only one God.
** Brother Aidan discusses this also while mentioning Crom Cruach, saying he doesn't know what parts of the story are true, only that one of Crom's eyes was used to illuminate books. This gives Brendan the idea to seek out Crom Cruach to get the crystal.
* ArrowsOnFire: The Vikings are fond of these.
* ArtInitiatesLife: [[spoiler:How Brendan beats Crom Cruach.]]
* ArtShift
** The monks' stories and Brendan's slate sketches. The art shift during the stories that talk about Colm Cille, or Saint Columba, doubles as a GeniusBonus because it imitates the style of manuscripts being produced at Colm Cille's time; a style categorized as the early insular gospels, and designed for the ease in Pagan conversion by presenting Christian aspects in a comprehensible comic-book-like format. ShownTheirWork indeed.
** During a dramatic action scene when the Norsemen attack, the art suddenly gains perspective.
** Crom Cruach's lair has a slightly different art style to emphasize it's otherworldly nature, being all angular lines and glowing green on black. In fact, this appears to be a bit of an in-universe thing as Brendan is somehow able to utilize its ''two dimensionality'' to his advantage by trapping Crom Cruach in a chalk circle.
* AwLookTheyReallyDoLoveEachOther:
** Cellach is often harsh with his nephew, telling him he is a disappointment and locking him up to punish him. [[spoiler: But then Cellach desperately attempts to save Brendan during the Viking attack, and when he believes Brendan dead, his haunting grief lingers for decades.]] It's clear that he deeply loves his nephew, even if he's not the best at showing it.
** Brendan's relationship with his uncle is rocky. When Aisling asks him if he has a family, he says no. But he still defends his uncle when the other monks mock him. [[spoiler: He is utterly devastated when Aidan forces him to leave his uncle for dead during the Viking attack.]]
* BadassPreacher:
** Cellach who takes an arrow to the chest, and has to be knocked down by Vikings before he stops protecting his nephew.
** Colm Cille who took an ''eye'' from a Pagan god just to use it as a magnifying glass.
* BaitAndSwitch: When Brendan prepares to sneak out, Pangur Ban appears seemingly to warn him about going to find Crom Cruach's eye. It's actually because Abbot Cellach is outside waiting to bust Brendan for sneaking out again.
* TheBeastmaster: One of Aisling's abilities; she controls the local wolf pack, and uses them to defend her forest [[spoiler:and her friends, like when Brendan and Aidan are nearly killed by a pair of Vikings]].
* BeneathTheEarth: The mound of Crom Cruach.
* BigDamnHeroes: [[spoiler:Aisling's wolf pack saving Brendan and Aidan from the vikings.]]
* BigNo: Brendan releases one when seeing [[spoiler:his uncle wounded in the snow during the Viking raids.]]
* BigOlEyebrows: Aisling. All the characters have big eyebrows, but Aisling's are the most prominent, not to mention they aren't even the same colour as her hair. [[WordOfGod Tomm Moore]] has stated that he partially based Aisling on his sister when she was young, and she also had prominent eyebrows.
* BilingualBonus:
** The book page Brendan and Aisling are climbing on in one of the montages reads "And so the little red-haired monk excelled at illumination but stayed mediocre in Latin"
** Bonuses exist for anybody who speaks or understands Irish:
*** In the forest Brendan begins reciting the Lord's prayer in Irish: ''Ár nAthair, atá ar neamh.."
*** Aisling's song. It translates: "There is nothing in this life but mist, and we will only be alive for a short time." Aidan also utters these exact lines elsewhere in the movie.
*** [[spoiler:The poem read after the credits]]
*** While climbing the tree, Aisling points to some bugs, and says, "Aithníonn ciaróg, ciaróg eile." This is an Irish saying, literally meaning, "One beetle recognizes another," (which Brendan understands and helpfully translates) but more colloquially, "It takes one to know one."
* BittersweetEnding: [[spoiler:Aisling seemingly gives up her humanoid form helping Brendan into Crom Cruach's cave, the Vikings ravage Kells and kill most of the inhabitants, but Brendan and Aidan escape and finish the book. Aidan eventually passes and Brendan himself eventually returns to Kells, guided by wolf Aisling (who briefly flashes to her fey form) and raises the spirits of his broken spirited and aged uncle in the end by letting him look at the finished product he thought destroyed.]]
** [[spoiler:Aisling's loss of human form is even dependent on if one considers WesternAnimation/SongOfTheSea as a StealthSequel as in it she appears in her human form in 1987 Ireland.]]
* BlackIrish: One of the monks is from North Africa. His design raised the hackles of a few reviewers unfamiliar with the Celtic art style.
* BlackSpeech: What the Northmen speak. Though sometimes they say a word that sounds a lot like "gold", since that's what they're after.
%%* BodyToJewel %% zero context
* BondingOverMissingParents: This is what gets Aisling to soften up to Brendan.
%%* BreakTheHaughty: Abbot Cellach. %% zero context
%%* BunnyEarsLawyer: Aidan. %% zero context
* CallingTheOldManOut: Brendan does this to his uncle about caring more about the wall than the Book, and how Cellach ought to know about how important the Book is, having once been an illuminator. Cellach responds by locking up Brendan until he can behave.
%%* CallToAdventure %% zero context
* CatsAreMagic: In a sense; since Aisling is apparently unable to free Brendan from his room in the tower, she turns Pangur Ban into a spirit so she can free him from the inside. This harkens back to the Celtic belief that cats were capable of going to otherwordly realms that others couldn't enter.
** FridgeBrilliance: As a fairy, Aisling may not be able to enter a tower filled with Christian paraphernalia.
* CatsAreSnarkers: Pangur Ban can't speak, but [[SilentSnarker her expressions]] more than make up for that.
* ChekhovsGun: Green ink. [[spoiler:Specifically, the [[SmokeOut smoke side-effect]] caused by it.]]
** Subverted with the Book's purported ability to blind the sinners who read it. The buildup right before [[spoiler: the greedy viking opens it]] really leads you to believe a miracle will happen at any moment and divine light will blind him. [[spoiler: This makes it all the more shocking when he does just fine and tears it all to pieces.]]
* ChekhovsSkill: Brendan's ability to draw [[spoiler:lets him defeat Crom Cruach with a bit of ingenuity.]]
* CircleOfStandingStones: The first meeting of Brendan and the fairy Aisling takes place inside a stone circle.
* CoolAndUnusualPunishment: After forbidding him from working on the book, Abbot Cellach locks up [[spoiler:Brendan in the scriptorium with the book during the Viking raid.]]
* CoolTeacher: Brother Aidan
* CreepyCrows: Heralds of the Norsemen. [[FridgeBrilliance And, by the way, associated with the goddess of war in Irish folklore and the Norse god of death and battle.]]
* CueTheSun: When adult Brendan returns to the abbot.
* CuteKitten: Pangur Ban
* CuteLittleFangs: If you look very closely in one scene, you can see that Aisling has them. They're [[FangsAreEvil made more obvious]] in an earlier scene when she tries to intimidate Brendan into leaving her forest. It's a very quick scene, but if you pause at just the right second here, [[NightmareFace her face is pretty scary]].
* DeniedFoodAsPunishment: Subverted; Abbot Cellach makes sure that Brendan is fed while he is locked up, even telling the monks to give his breakfast to Brendan.
%%* DesignStudentsOrgasm: In a family-friendly sense.
* TheDeterminator: Although Abbot Cellach [[spoiler:is shot with a flaming arrow, struck down and ran through with a sword, and left for dead on an Irish winter's night, he simply refuses to die and, after being retrieved, goes on to live for around two decades.]]
* DidntThinkThisThrough: Double-subverted. When Brendan ponders going into the forest to get the berries that Brother Aidan needs, he draws out the potential drawbacks. Once in the forest, however, he doesn't know what the berry trees look like or how to get home.
* DidYouJustPunchOutCthulhu: Brendan [[spoiler:manages to defeat Crom Cruach]]. Keep in mind, this is a monstrosity that has [[spoiler:killed off most of Aisling's people]], a race of very powerful, very well-armed warriors. And he does it [[spoiler:with chalk]].
%%* DisneyAcidSequence: The Book of Kells itself.
* DisneyDeath: Cellach thinks that [[spoiler:Brendan and Brother Aidan died when the scriptorium burned during the Viking Raid. He doesn't find out the truth until Brendan returns to Kells as an adult.]]
%%* DistantFinale
* TheDreaded: The Vikings and Crom Cruach.
* EasterEgg: When Aidan is throwing things around while looking for the Eye, a couple sheets of animation paper go fluttering through the air.
* EasyEvangelism: Completely averted:
** Abbot Cellach mentions that most of the refugees are Pagans and Crom worshippers and believes that "it's with the strength of our walls that they will come to accept the strength of our faith."
** [[spoiler:At one point a viking warrior gets to have a look at the Book of Kells (which is a [[Literature/TheFourGospels Book of the Gospels]]), only to rip out all of the pages and throw the book away a few seconds later, clearly unimpressed.]]
** Also averted with Aisling. Despite knowing how important the Book is to Brendan, she never converts. This is probably because pre-Christian Celtic demi-deities don't really care for Christianity, or any religion for that matter.
* EccentricMentor: Aidan, and presumably Aidan's old mentor from what we hear of him.
* EldritchAbomination: Crom Cruach can be considered one.
* EvilUncle: The Abbot (aside from [[CaptainObvious the Vikings]]) seems to be an antagonist at first, and [[http://img52.imageshack.us/img52/9605/abbottcopy.jpg early concept art]] definitely depicts him as more typically "evil"-looking. Ultimately subverted, though, since despite being extremely strict he does genuinely care about Brendan.
* {{Eyedscreen}}: The sudden focus on Brendan's eyes when he first enters the forest. Also used on the last refugee to arrive before the Viking invasion.
* FailedASpotCheck: After locking Brendan up, Abbot Cellach trusts the other Brothers to make sure Brendan stays there and that he is fed, while never checking the room. He doesn't even notice the activity in the scriptorium until green smoke comes out, or the Brothers assisting Brendan in the illumination, because he's so focused on the wall. [[spoiler:He does bust them eventually when the Brothers are careless in cheering on Brendan for his drawing.]]
* TheFairFolk: Aisling, who is friendly for the most part, but will not hesitate to sic her wolves on people who trespass in her forest. WordOfGod says she's one of the Tuatha Dé Danann, a [[OurElvesAreBetter powerful divine race in Irish mythology]].
* FantasyForbiddingFather: Abbot Cellach to his nephew Brendan, forbidding he do most anything not wall-building related.
* FelonyMisdemeanor: Brendan gets in trouble for anything related to illuminating books, even learning to ink with a quill.
* FiveTokenBand: Of Irish Catholic monks. Think about that a moment. An Irish monk, an Italian monk, a Chinese monk, an African (Moor) monk, and an English monk, who was originally supposed to be Afghanistani. (There's also a monk with a German accent, a gloomy Slav, and a French monk (albeit without any lines in the final version).) It isn't explained how they all got there ("there" being a 9th century Irish monastery) but according to WordOfGod they represent the different artistic influences in the book.
* FlatEarthAtheist: Brendan initially dismisses Crom Cruach as a story to scare children and says that Abbot Cellach told him never to worry about pagan fairytales. He tells all this to Aisling, whom he ''recognized as a fairy'' when they first met.
* ForYourOwnGood: Cellach locks Brendan in his room to protect him after Brendan refuses to give up visiting the forest and working with Brother Aidan.
-->'''Cellach''': If I can't trust you to stay out of harm's way, you'll have to remain here until you see sense.
* {{Foreshadowing}}:
** Brendan breaking through the scaffolding while chasing the goose.
** The scene of Brendan touching a goose feather is repeated twice; the second time just as he's about to start his first proper illumination and the first time as, well, this very trope.
* FunnyBackgroundEvent: While Aidan and Brendan talk about important things, Pangur Ban slowly slides through Aidan's arms, her expression becoming more indignant by the second.
* FunnyForeigner: The monks are of multiple ethnicities, and some of them are comic relief characters, especially the Italian monk Brother Leonardo who is chasing a goose and falling in the mud in his first scene.
* GenderFlip: In the Irish poem ''Pangur Bán'', the cat is male.
%%* GoodIsNotNice: Abbot Cellach. %% zero context
* GoodScarsEvilScars: The comic book [[http://www.comixology.com/The-Secret-of-Kells-Prequel-1/digital-comic/ICO000385P prequel]] reveals the Abbot's scar came from [[spoiler:a Viking's sword while rescuing Brendan as a toddler.]]
* GoryDiscretionShot:
** The stabbings of [[spoiler:the dock worker]] and [[spoiler:Abbot Cellach]] happen off-camera.
** It's also heavily implied but not explicitly shown that [[spoiler:the monks and villagers holed up in the church instead of the tower]] don't survive the attack, as their scene ends with the Vikings bursting through the door.
* {{Greed}}: The Vikings plunder and kill to search for gold.
* GreenThumb: Aisling. Notably, she seems to be able to make small white flowers grow out of solid rock.
* TheGrimReaper: Abbot mistakes [[spoiler:the adult Brendan]] for this.
* HardWorkMontage: Brendan's training, interspersed with the Abbot's work on the wall.
* HellFollowsWithMe: Aidan's journey to Kells is all about this.
* {{Herald}}: Aidan is an ActionSurvivor; see below.
* HeroicSacrifice:
** When entering Crom Cruach's lair, [[spoiler:Aisling holds the entrance long enough for Brendan to get in, even though Cruach's black vines grab her.]]
** Cellach tells the [[spoiler:refugees in the tower to close the door, and then stays on the ground as the Vikings attack to rescue Brendan.]]
* HoistByHisOwnPetard: [[spoiler:Unintended on Brendan's part, but after trapping Crom Cruach in a chalk prison and blinding it, the monstrous abomination, unable to lash out at anything else, proceeds to consume itself.]]
* HopeSpot: Once Brendan gets [[spoiler:Crom Cruach's eye, he and the other priests start to work on the book in earnest, avoiding Abbot Cellach's scrutiny and finishing the beloved page. Then the Vikings attack and the Abbot locks up Brendan in the scriptorium after busting him and the priests.]]
* HornyVikings: To the point where the Northmen seem more like monsters than people, moving slowly, growling in BlackSpeech, and looking like huge dark blocks with limbs. [[FridgeBrilliance Of course, this is how the Medieval Irish would have viewed them]].
* HypocriticalHumor: "You can't learn everything from books." "I think I read that somewhere."
* IAmDyingPleaseTakeMyMacguffin: [[spoiler:Aidan's reputation is as "the perfect illuminator," and Brendan calls his book the work of angels. But his eyesight's going and his hands are too unsteady to finish the book, hence enlisting Brendan's help.]]
* IGaveMyWord: An implicit example with the abbot. As he lies wounded and goes through his [[HeroicBSOD BSOD]] DespairEventHorizon moment, he is reminded that he, in fact, ''cannot'' give up, since he's the abbot (i.e. the leader of his people). It is enough to make him get up.
* ImplacableMan: The Vikings. Every shot we see them in is basically them slowly moving. We never see them run at all, or even show any sort of fear, [[spoiler:except for the two that are killed by Aisling's wolves.]]
* IronicEcho: The first time Aidan says "There's nothing in this life but mist" he says it in a jovial manner, with the intention of saying life is filled with questions to be answered. Later however, he says it in a somber and resigned way indicating the hopelessness of uncovering the mist in the short time we live. Between these two bookends, it takes on a third, more literal meaning in Aisling's song when she sings these words (in Gaelic) as she turns Pangur Bán to mist. (She sings also of the shortness of life, but with wistful hope rather than Aidan's later defeatism.)
* JesusTaboo:
** Though the film is set in a monastery and most of the characters are Christian monks, the faith itself is not focused upon. The faith is mostly alluded to with the Book said to be that which will "turn darkness into light", and the relationship between the old religion and Christianity is touched upon symbolically. Justified in that the religious setting is mostly a background historical setting.
** The actual Book of Kells is in fact [[Literature/TheBible the Christian New Testament]], but the film does never actually spell that out.
** A large piece of the movie focuses on Brendan completing the Chi-Ro page. The Greek letters chi and rho were normally used in medieval manuscripts to abbreviate the word Christ, but this is never explained in the film.
* KickTheDog:
** When a wounded and unarmed Cellach trundles [[spoiler:to the scriptorium, to free Brendan before it burns down, the Vikings attack him.]]
** Also, the Vikings [[spoiler:tear up the book of Kells that took months if not years to illuminate.]]
* LargeAndInCharge: The abbot dwarfs everyone else living in Kells.
* LastOfHisKind: [[spoiler:Aisling is this for the Tuatha Dé Danann.]]
* LeftForDead: Abbot Cellach is so badly wounded by the Vikings' attack that they don't bother finishing him off.
* TheLightfooted: Aisling has a distinct and graceful way of moving, even when she goes down on all fours.
* LittleNo: Brendan gives one when Cellach forbids him from visiting the scriptorium and brother Aidan.
* TheLowMiddleAges
* MassOhCrap: The Abbey's residents when [[spoiler:the Vikings attack, starting by shooting flaming arrows over the wall, and then when the stairs to the tower collapse due to too many people using them.]]
* MeaningfulEcho: "There's nothing in this life but mist" is a phrase Aidan uses early in the film. He says it again later only more somberly with the additional phrase "and we're only here a short while". This whole phrase is then sung by Aisling shortly after, only it is sung in Irish with the lines "Níl sa saol seo ach ceo / is ní bhéimid beo ach seal beag gearr".
* MeaningfulName: The [[http://en.wikipedia.org/wiki/Aisling Aisling]] is a genre of Irish political poem usually lamenting the state of the Irish people. In Irish Gaelic, the word "aisling" literally means "dream" or "vision".
* MorphicResonance: Whenever Aisling is in a different form, she always retains her white hair color and her green eyes.
* {{Motifs}}
** Celtic knots are visible everywhere. Every snowflake, for starters.
** Circles and spirals are also very frequent there. Spirals apparently represent nature while circles are related to civilization, religion and art. Incidentally, the Book of Kells contains heaps of both.
* MyGodWhatHaveIDone:
** Aidan calls himself an old fool when he gets Brendan into trouble with his uncle in recruiting him for the book. He tries to ShooTheDog when Brendan appears [[spoiler:with Crom Cruach's eye.]]
** Cellach. [[spoiler:As the sacking of Kells begins, it begins to get through to the Abbot that, despite all his preparation, things aren't going to work out. And what follows is a massive slaughter that basically makes the rest of his life one really prolonged version of this trope.]]
* MyParentsAreDead: A variant of this occurs when Brendan and Aisling first meet:
-->'''Brendan:''' I don't have a family, and we have food in Kells, so I wouldn't have come here for it anyway. I was just... a bit lost.\\
'''Aisling:''' You have no family?\\
'''Brendan:''' Uh... no.\\
'''Aisling:''' No mother?\\
'''Brendan:''' ''(looks down, not saying anything)''\\
'''Aisling:''' ...I'm alone too.
* MysteriousMist: When the fairy Aisling makes her first appearance, the forest fills with mist. This is a nod to the notion of Myth/IrishMythology that the Tuatha Dé Danann concealed themselves in a magic mist (the "fairy mist") from observers. The mist dissipates as Aisling becomes more friendly towards Brendan.
* MysticalWaif: Aisling, though she's more assertive than most mystical waifs.
* MysticalWhiteHair: Aisling. [[spoiler:In the second comic prologue, it's revealed to be a racial trait of TheFairFolk.]]
%% * NatureSpirit: Aisling %% zero context
* NeverSayDie: [[spoiler:Aidan's footsteps are washed away in the sand next to Brendan's and Pangur's footsteps]]. Though averted when Aidan states that he would have been killed had he not fled Iona, and again when Aisling tells Brendan that he will die if he confronts Crom Cruach; all of the ''actual'' deaths are implicit.
* NoKillLikeOverkill: The Vikings make it a strong point to wipe out everyone in Iona except Aidan who escaped, and [[spoiler:do the same to most of the residents at Kells, even when it wouldn't benefit them.]]
* NoOneGetsLeftBehind: Subverted. [[spoiler: Aidan and Brendan leave Cellach for dead, despite Brendan's protests.]]
-->'''Brendan''': We have to save him!
-->'''Aidan''': We can't help him now.
* NobleWolf: Aisling gives off this vibe while in her wolf form. The other wolves she controls [[SavageWolves are different]].
* NonHumanSidekick: Pangur Bán, who is apparently intelligent enough to go into the woods and find Aisling when Brendan needs help.
* OhCrap:
** Brendan when his Uncle busts him for sneaking out into the forest, both times.
** Brendan and Aidan when [[spoiler:the Vikings catch up to them in the woods and take the book.]]
%%* OminousFog %% zero context
%%* OminousLatinChanting %% zero context
* ParentalAbandonment
** Brendan's parents were [[AllThereInTheManual killed by Vikings]] when he was a baby.
** Aisling's [[spoiler:mother]] was killed by Crom Cruach, [[spoiler:along with the rest of her people]].
* ParentalSubstitute: Brother Aidan promises to be one [[spoiler:when he and Brendan think that Abbot Cellach is dead.]]
* PeopleOfHairColor: All the native Irish whose hair hasn't turned white.
* PetTheDog: Abbot Cellach has a few moments that actually show he's not an EvilUncle and foreshadow his eventual HeelRealization.
** At one point, a group of refugees arrives in the village. Abbot Cellach lets them in without hesitation.
** It's shown several times that he's one of the hardest workers on the wall.
** It's briefly shown at some point that he's actually saddened by his decision to [[spoiler:lock up Brendan]]. He also makes sure that he's still fed and at one point asks a monk to bring his own breakfast to [[spoiler:Brendan]].
* PintSizedPowerhouse: Aisling is shown to be quite strong for her small size, considering how she pulls Brendan up like it's nothing when he's dangling from a tree branch and when she lifts a statue much larger than herself to help Brendan get inside Crom Cruach's cave.
* RapunzelHair: Aisling
* ReallySevenHundredYearsOld: Aisling is implied to be much older than she looks, and if her opening narration and [[spoiler:her brief reappearance in her Fey form near the end of the film]] are anything to go by, she may not even age. Unsurprising, since she's one of TheFairFolk.
* RedHerring: When Brendan is locked up, he tells Aisling to go get Brother Aidan to see if he might get the key. Aidan had previously talked about Crom Cruach's eye and thus has less ArbitrarySkepticism about the Fair Folk. Aisling decides to use Pangur Ban and her magic, however.
* RedSkyTakeWarning: Often accompanies the Vikings. Makes sense, since they love to burn everything, and lots of firelight reflected off the clouds is one of the natural ways to get this trope.
* ReptilesAreAbhorrent: Crom Cruach is a giant serpent, though his appearance owes more to deep-sea fish. [[spoiler:And it's made of jointed ''drawings''. Brendan uses this to his advantage.]]
* RoomFullOfCrazy: Abbot Cellach's room is painted with the plans for the town wall as well as a map of Kells on the floor. It's all sketched out with chalk in medieval non-perspective, to suggest the Abbot's obsessive devotion to completing the wall. A little different from usual in that he's sane -- to a fault.
* RunningOnAllFours: Aisling can run on all fours, probably to show her connection to nature and how wild she is.
* SavageWolves: Aisling leads a pack of them. Initially they play the trope straight when they attack Brendan on his first journey into the forest, but they later pull a BigDamnHeroes moment when [[spoiler:Aisling rallies them against the Vikings who ambush Brendan and Aidan after they flee from the massacre at Kells.]]
* ScaledUp: Crom Cruach should not have turned into a snake. It never helps.
%%* SceneryPorn %% zero context
* SeasonalMontage: At the end of the film.
* TheShadowKnows: When Pangur Ban is in spirit-form, she still has the shadow of a cat.
* ShownTheirWork: Some of the artistry in the film goes beyond taking inspiration from the Book of Kells and is directly based on it. The Chi-Rho page is faithfully reproduced. Brendan's first work [[spoiler:using the crystal - the drawing that Cellach angrily rips from its frame and later keeps as his "only comfort"]] - is visible in the bottom left corner of the real Chi-Rho page at the tail of the Chi.
* SilentSnarker: Some of Pangur Ban's expressions are ''priceless''.
* SnowMeansDeath: [[spoiler:The attack on Kells.]]
* SpeaksFluentAnimal: Being so closely connected to nature, Aisling is implied to be able to do this, especially when she tells Brendan that she asked some wasps not to sting him when they find the oak galls.
%%* AStormIsComing %% zero context
* SurvivorGuilt:
** Abbot Cellach at the end of the film [[spoiler:is left broken because of his guilt]].
** We see a flash of this in Brendan [[spoiler: as he and Aidan leave Kells, [[LeftForDead leaving his uncle for dead.]]]]
** Subverted in the case of Aidan, who seems fairly cheerful and upbeat despite being the only survivor of Iona. Although maybe he's keeping his darker feelings hidden from young Brendan.
%%* SwordOfPlotAdvancement: The Eye of Crom Cruach. %% zero context
* TakeOurWordForIt: {{Subverted|Trope}}. They avoid showing the contents of the book for most of the film, only to show [[spoiler:the completed Chi Rho page]] at the end.
* TimeCompressionMontage: The scene showing Brendan's education in art. On a side note, the film takes place over the course of a year (shown by the change in seasons).
* [[BilingualBonus Trilingual Bonus]]: Aisling's song in Irish and the page of Latin Brendan and Aisling are shown running across. The first Latin sentence reads: "And so the little red-haired monk excelled at illumination but stayed mediocre in Latin."
* UncattyResemblance: The sheepherder. "Baaaaa!"
* VeryLooselyBasedOnATrueStory
** Scholars put the creation of the book around the year 800, which means Colm Cille (d. 597) can't have had a hand in it, and the historical [[http://www.bedesworld.co.uk/aidan.htm St. Aidan]] [[note]]Not so fun fact: the real St. Aidan and his voice actor Mick Lally both died on August 31st[[/note]] lived over 150 years earlier. Also, the cover wasn't stolen for another 200 years or so. There's not much we know for sure about the creation of the book (it might have been produced entirely at Iona or Kells, or some combination, or even Lindisfarne), so they had to take some liberties in order for there to be any plot. [[LampshadeHanging Lampshaded]] when the monks at Kells can't agree on the history, either, including Colm Cille's methods (third eye? three hands? 36 FINGERS?!), and simply get their facts wrong. One monk says the book was begun 300 years ago by Colm Cille; impossible if Aidan knew him.
** And Pangur Bán was owned by an anonymous Irish monk in a ''German'' monastery.
** Crom Cruach does exist in Irish mythology, where's he described as a Pagan god whose worship included human sacrifices and he was banished by St. Patrick. He has nothing to do with Colm Cille.
** There was an Abbot Cellach who was abbot of Iona. He retired to Kells in 814 AD and died the next year. [[https://orthodoxwiki.org/Abbot_of_Iona He is credited with building a church in Kells]].
** Brendan is 12. The prequel comic, in which Cellach rescues infant Brendan from the Vikings, is dated 790 AD. That means the events of the movie take place in 802 AD. [[http://www.educationscotland.gov.uk/scotlandshistory/britonsgaelsvikings/vikingraids/index.asp This was the year of an actual Viking invasion of Iona]], just as Aidan describes, and therefore the likely date that the Book of Kells moved to Kells - or at least, left Iona.
* VoluntaryShapeshifting: Aisling is a fey that takes on the form of a white wolf at will, and she's shown to have also taken on the forms of a salmon and a deer in the past. [[spoiler:Unfortunately, she seems to suffer ShapeshifterModeLock after nearly giving her life to get Brendan into Crom Cruach's lair. [[FridgeBrilliance Then again]], as the local wolf pack already accepts her as their leader, [[TrueCompanions she's finally got a family again]].]]
* WalkingTheEarth:[[spoiler:Aidan and Brendan after the Vikings attack Kells.]]
* TheWallAroundTheWorld: Abbot Cellach is obsessed with building a wall to protect his monastery from Viking invasions. [[spoiler: It doesn't work.]]
* WallCrawl: Aisling can do this through magic.
* WellIntentionedExtremist: Abbot Cellach is a mild example. He acts like a total {{Jerkass}} who is obsessed with building his wall, to the point where he disdains and eventually forbids his monks from doing anything else. However, the point of the wall is to keep out the Vikings, who already killed all the family he had except for his young, impressionable nephew, who now wants to do non-wall related things like go outside and create beautiful holy books. [[spoiler:He doesn't listen when Aidan tells him that his wall won't hold and they should all flee instead, which leads to disaster, and his HeelRealisation.]]

* WhyDidItHaveToBeSnakes: Aisling can't enter the buildings in the Abbey, but she comes anyway to free Brendan after seeing him locked up, while visibly trembling and shaking. She's also afraid of Crom Cruach but agrees to help Brendan go into his lair. [[spoiler:Aisling reveals that it's because Crom Cruach wiped out her people, including her mother.]]
