->''And some things that should not have been forgotten were lost. History became legend. Legend became myth. And for two and a half thousand years, the Ring passed out of all knowledge.''
->-- '''Lady Galadriel''', ''Film/LordOfTheRings: The Fellowship of the Ring''

A thousand years ago, the Glorious Hero led a rebellion against the oppression of the [[NamesToRunAwayFromReallyFast Evil Emperor McDoom]], rallying an army of downtrodden peasants, StormingTheCastle of the dark empire, and defeating the emperor in hand-to-hand combat. His wise leadership ushered in a GoldenAge of peace and prosperity that lasted for four generations, and he is remembered fondly to this day as the great founder and establisher of freedom in the land.

...huh? Wait a second, that's not right at all! See, this isn't just a backstory; his story was actually told in the previous series. He didn't raise the rebellion; he just got caught up in it, and the attack on the castle was just a diversion so he could catch the emperor alone and assassinate him with a dagger InTheBack. [[CombatPragmatist (It was the most expedient way to get rid of the guy.)]] And no one called him "glorious hero" until many years later, when he had dedicated most of the rest of his life to cleaning up the mess left behind by the power vacuum he helped create.

You know this as the reader, but the characters 1000 years later don't. No one from back then is still around today. The language has changed, and ancient records have never been all that good at remaining intact, so certain facts tend to get distorted over time.

The TropeNamer is the [[OpeningNarration introductory passage]] at the beginning of each ''Literature/TheWheelOfTime'' book: ''The Wheel of Time turns, and Ages come and pass, leaving memories that become legend. Legend fades to myth, and even myth is long forgotten when the Age that gave it birth comes again.''

This trope only covers instances where the audience is already familiar with the original picture, and then can see the mythology it gets turned into by later generations.

See AndManGrewProud for when the legend of sorts was a catastrophe instead. Compare FutureImperfect, when it's the audience's era being misremembered like this. Not to be confused with ShroudedInMyth, which is when the mythologizing process happens while the subject of the myth is still alive.

[[folder: Anime And Manga ]]


* The origins of the EasternZodiac in ''Manga/FruitsBasket''. Tohru's mother told her the legend of the Zodiac when she was little, which tells how the Rat tricked the Cat into missing the feast, which causes the Cat to be left out of the Zodiac. The Members of the Zodiac seem to believe this legend, as well, considering that it's one of the main reasons Yuki (the Rat) and Kyo (the Cat) hate each other's guts. However, the true story (which is revealed to the reader, but not the characters, toward the end of the series) turns out to be much different - most notably, the ''Cat'' was [[spoiler:the closest one to God, until he asked WhoWantsToLiveForever]], while the Rat [[spoiler:just happened to be the first animal to be made immortal (after the Cat)]].
* Humanity in ''{{Anime/Diebuster}}'' barely has any records of the events that transpired during ''{{Anime/Gunbuster}}''.
** They are aware that the black hole Exelio at the outskirts of the solar system was man-made in order to stop a Space Monster invasion (and indeed, it was created by [[spoiler:the self-destruct of [[CoolStarship the battleship Exelion]]]]) but falsely believe it was also the event that took out the Space Monsters' main forces (that was [[spoiler:the Black Hole Bomb AKA Buster Machine No. 3, an entirely different vehicle used in an entirely different location in an entirely different battle]]).
** They are also aware that humanity once possessed [[FasterThanLightTravel warp technology]] powered by [[AppliedPhlebotinum degeneracy reactors]] but intentionally sealed the tech away to prevent drawing attention to themselves like they did with the Space Monsters.
** At the same time, they have no records left about any of the single-digit [[SuperPrototype Buster Machines]] or their pilots and completely forgot about the Sol Absolute Defense System, a [[MechanicalEvolution self-evolving]] fleet of [[MechaMooks unmanned Buster Machines]] defending the Solar System from threats - in fact, [[spoiler:the whole conflict in ''Diebuster'' is caused by the emergence of the [[RealityWarper Topless]] causing the fleet to [[HumanoidAbomination mistake humanity for Space Monsters]] and [[GoneHorriblyRight attack]], leading to humanity looking at their [[StarfishAlien decidedly not-of-this-world]] attackers and mistakenly thinking said attackers are the [[TheDreaded legendary]] [[EldritchAbomination Space Monsters]]]].
** The whole thing is epitomized by Nono, a strange RobotGirl who constantly babbles on about a person called Nonoriri whom she really wants to meet for a reason she doesn't know. Then it is revealed that Nonoriri is [[spoiler:Noriko Takaya, the protagonist of ''Gunbuster'' who went missing in action after detonating the Black Hole Bomb in a kamikaze attack. Nono is actually a [[PintsizedPowerhouse miniaturized]] [[SuperweaponSurprise Buster Machine]] designed specifically to mount a search-and-rescue mission for the Gunbuster but ultimately ended up embedded into a long-period comet for several millenia.]]
** All this is justified by the revelation at the end of the series that [[spoiler:''Diebuster'' takes place 12,000 years into the future, just a year before [[ContinuityNod Noriko and Kazumi finally return to Earth]] after their kamikaze run at the end of ''Gunbuster'' exposed them to massive TimeDilation]]. But despite the amount of time that had passed, [[spoiler:humanity still remembers their saviors well enough to set up the [[TearJerker most memorable]] [[CrowningMomentOfHeartwarming scene of the franchise]]. Welcome home, girls.]]

[[folder: Comic Books ]]

* After DC Comics' ''CrisisOnInfiniteEarths'' reboot, due to the fact that so much of the old "Earth-1" continuity was pivotal to the ''Comicbook/{{Legion of Super-Heroes}}'' canon, the pre-Crisis version of history was presented as the 30th century's distorted legends of the "actual" (post-Crisis) continuity. (For a while, at least. But then some {{RetCon}}s were made, and a ContinuitySnarl set in, so who knows is this is still the case in the current version of the Legion.)
* In one ''ComicBook/FantasticFour'' arc they come across a town suffering from [[YearInsideHourOutside Decade Inside Second Outside]]; inside the town the FF are considered legendary heroes (even more so than in Earth-616 RealLife) and are quite upset when they find out about how the FF are really.

[[/folder]]

[[folder: Film ]]

* The religious myth held by the apes in the first ''PlanetOfTheApes'' movie turns out to be a distorted version of Caesar's rebellion and the human war that allowed apes to come to power as depicted in the sequels.
* The prologue to the ''Film/LordOfTheRings'' movies says this is why things came to be as they were at the end of the Third Age: people forgot about past threats, and grew complacent. Sauron exploited that. An unusual example in some ways, as some Elves who witnessed the events in question are still around thousands of years later, but most Men have grown estranged from and fearful of them, and thus don't know the facts.
** Also used in a meta way, as Middle-earth is a fictional past of our world before the Ice Ages...but those events were forgotten save for vague legendary hints. This would have been expanded upon in ''[[TheHistoryOfMiddleEarth The Book of Lost Tales]]'' and ''[[TheHistoryOfMiddleEarth The Lost Road]]''
* A comparatively modern example happens in ''Film/TheRageCarrie2''. Rachel mentions that a mountain of conspiracy theories has cropped up about "what ''really'' happened" during the events of [[Literature/{{Carrie}} the first film]], sarcastically claiming that Carrie went up with Music/ElvisPresley in a UFO. The only thing that everybody can agree on is that Carrie burned down her high school on prom night [[spoiler:and then killed herself and her mother]].

[[/folder]]

[[folder: Literature ]]

* As noted above, ''Literature/TheWheelOfTime''. The series describes history as a circular repetition of seven Ages, and the story is set in the Third Age, which is both after and before our own time. One minstrel in the first book claims to tell tales of an ancient Age which are recognizable as distorted memories of the 20th century, and many of the events of the series bear a distinct resemblance to any number of what we know as ancient mythologies.
** Also happens in-universe every now and then, particularly with Birgitte, who's met half the heroes of the legends in person and probably ''[[{{Reincarnation}} been]]'' the other half.
** The TropeNamer comes from a line at the beginning of every book, but there's a short-term example of it at the end of most books too. Most of the novels end with a line about how rumors and legends spread about the important event at the climax of the book, and how they would be [[GossipEvolution wrong and/or contradict each other]] about most details, but would usually get the most important detail right. Legend fading to myth within a year or so, in-universe.
* ''Literature/TheAlloyOfLaw'', by BrandonSanderson, is set 300-odd years after the {{Mistborn}} trilogy. The events of the trilogy have taken on mythological and religious significance to the later generations. The most humorous of these changes is the ancient [[SacredLanguage High Speech]]; when an example of it is given, it's quickly recognizable to readers as the [[JiveTurkey silly-sounding thieves' cant]] used by a few characters in the original trilogy!
* In ''Dragonsinger'' from the ''DragonridersOfPern'' series, we are introduced to the legend of Moreta, the Dragonlady who saved Pern from a deadly epidemic at the cost of her own life. ''Moreta: Dragonlady of Pern'' (published at a later date) recounts the actual events that gave rise to the legend.
* Another backwards-example from Creator/ElizabethMoon: Gird is considered to be either a saint or a god in ''Literature/TheDeedOfPaksenarrion'', then the author went back and wrote the Legacy of Gird books to show what really happened.
** Foreshadowed in the books when ancient contemporaneous accounts of Gird are found in a lost fortress. Apparently their saint was a bit of a BoisterousBruiser, which is not a surprise, and TheAlcoholic, which is.
* In ''TillWeHaveFaces'' Orual lives long enough to see her sister's life become the Eros And Psyche myth.
* In "The Sorrow of Odin the Goth" by Creator/PoulAnderson, a time traveler is actually responsible for events in a Gothic tribe that will later become mythologized in the Icelandic ''Literature/VolsungaSaga'' ... events which are much more painful, human and error-filled at the time than later generations will realize.
* ''Literature/SeptimusHeap'':
** Five hundred years after Queen Etheldredda's death, her actual gain of immortality and trapping in the Palace attic have become a myth that is recounted in ''The Magykal Papers''.
** The myth of the Black Fiend that lives in the Summerhouse of the Palace seems like a follow-up of [[PantheraAwesome Ullr's]] exploits 500 years earlier.
* Used several times in ''Literature/TheLordOfTheRings'': Even when elves are immortal and remember the distant past, they cannot be everywhere, so Gandalf only learns how to identify the One Ring by reading a scroll that is obscure even to the lore-masters, for their scripts and tongues have become dark to later men. A lot of legends are lost because they don’t have a translation to the common tongue, Celeborn claims that “Old wives keep in memory word of things than once were needful for the wise to know”, and it seems that only the hobbits, with their obsession for stories and relationships, wrote history books. The book even shows that ''The Lord of the Rings''' story will eventually be forgotten and replaced by Myth:
-->''The second disappearance of Mr.Bilbo Baggins was discussed in Hobbiton, and indeed all over the Shire, for a year and a day, and was remembered much longer than that. It became a fireside-story for young hobbits; and eventually Mad Baggins, who used to vanish with a bang and a flash and reappear with bags of jewels and gold, became a favorite character of legend and lived on long after all the true events were forgotten.''
* At the start of ''Literature/ACanticleForLeibowitz'', after the Simplification, humanity's knowledge of its own history has so far degraded that they think [[WorldWarIII the Flame Deluge]] was caused by supernatural forces. It's ultimately inverted, though, in that after another several hundred years, they manage to piece together what really happened [[spoiler:just in time for it to happen all over again]].
* ''Literature/TheSagaOfRecluce'' uses this a lot, as each book mentions a legend or a myth and the actual event is recounted in a separate book, often bearing little resemblance between the event and the legend/myth. Once such instance is the Legend itself.
* In ''{{Holes}}'' the main character says that he had a great-great-grandfather who had stolen a pig from a one-legged Gypsy, and she put a curse on him and all his descendants. The truth actually makes the ancestor, Elya, more sympathetic--he wanted to use the pig for a bride price, and in return, the Gypsy, Madame Zeroni (who actually was only missing a foot) told him he had to carry her up a mountain to drink from a special stream that would restore her strength. After realizing that the girl didn't love him, however, Elya impulsively got on a boat to America and only belatedly remembered his promise.
* A shorter term version of this happens to Harry Dresden of ''Literature/TheDresdenFiles''. We, the readers, know that every time he comes out on top at the end of the book, it's by the skin of his teeth and the help of his friends and allies, he barely survives, and he usually has a hospital stay and not much else to show for it after all's said and done. Others, like members of the White Council, don't know all that, so they see him as this badass superwizard who rides zombie dinosaurs and takes down nigh-invincible enemies single-handedly. This leads to amusing situations like a group of combat veteran Wardens ''hesitating'' to arrest him when Harry, in fact, is concussed and can barely stand up straight.
* The fifth series of ''Literature/WarriorCats'' is a {{prequel}} to the series called ''[[Literature/WarriorCatsDawnOfTheClans Dawn of the Clans]]''. In the first book, ''The Sun Trail'', a she-cat named Rainswept Flower falls into a hole on the moor. After main character Gray Wing saves her, his friends Shattered Ice and Jackdaw's Cry figure out that they can get shelter by tunneling under the moor. Thus, tunneling is invented. The following release, ''Tallstar's Revenge'', takes place in a more familiar time, which is many years after ''Dawn of the Clans''. In it, a hilariously skewed version of tunneling's origin is told where Shattered Ice is some lone action hero who braves a blizzard to dig a hole which saves everyone from starvation. Since it was mentioned in ''Secrets of the Clans'' that stories of the dawn of the Clans are told differently every time, and we've seen several of these stories, it can be reasonably assumed that we'll learn how ridiculously twisted some of the other ones are as well.
* The StarTrekExpandedUniverse novel ''Kahless'' involves a Klingon monk finding an ancient scroll dating back to the founding of the Klingon Empire and appears to have been written by Kahless himself after he left his throne to be alone. With the Empire in turmoil after the knowledge of the scroll is made public, Kahless II (the clone of the original) tries to find the truth and kill the lying monk, as his own memories contradict the scroll (then again, his memories are based on the official records). The scroll tells the story of Kahless in great detail. Kahless didn't rise up against the tyrant Molor becaues it was the right thing to do. He was Molor's faithful lieutenant until being forced into exile after killing Molor's son in a duel. The character of Morath, whom myth remembers as Kahless's brother whom Kahless fought for 12 days and 12 nights for telling a lie, was actually the driving force behind the rebellion, pushing Kahless to stay the course. During the final battle, which Klingon myths depict as a titanic struggle between Kahless and the giant Molor, Kahless and Morath burst into Molor's throne chamber only to find a frail man suffering from a sickness. He tricks Kahless into giving him a dagger to fall on only to throw it at Kahless. Morath takes the dagger for his friend before Kahless kills the tyrant with his CoolSword (which was made by a blacksmith not Kahless). If this is to be believed, than Kahless II is actually the clone of Morath, since the blood on the dagger was used as the genetic sample.

[[folder: Tabletop Games ]]

* ''TabletopGame/{{Warhammer 40000}}'' is full of this.
** The Emperor was ''not'' a god, half his campaigning was in order to eliminate the concept of religion (and one of his children turned against him because he ordered him to stop worshipping him). These days, he's the central figure of humanity's state religion.
** Many of the more primitive worlds ascribe SpaceMarine landings as the GodEmperor sending his Angels of Death, sometimes the Marines looking for initiates are remembered as selecting the worthiest to live with them in paradise.
*** Considering that those selected are the most Badass preteens in [[ProudWarriorRaceGuy often primitive warrior cultures]] and the [[ForeverWar state]] of [[CrapsackWorld the galaxy at large]] this superstition is [[WarriorHeaven fairly accurate]] and as such of a Subversion.
** Done heartbreakingly in a novel where a set of toys are seen in a shop...which date back to and originated in the Soviet Union. When asked what the letters (CCCP) stand for, the shop's owner says "No one remembers anymore."
** Taken to an even greater degree by the [[OurElvesAreBetter resident elves]], the Eldar. The Eldar's civilisation was annihilated in a cataclysmic event known as the Fall, and the only Eldar left in the galaxy are nomadic survivors, pirates, wanderers and a mysterious cult-like organisation dedicated to their trickster god Cegorach. Pretty much all of their vast history stretching back for millions of years has been lost, and what little remains is passed down through prophecy, allegory and song, which means their history becomes more fanciful through each retelling. Not even the Eldar themselves really know much about their history and culture, but it is suggested that a lot of it is based in fact. For example, the long lost "Talismans of Vaul" are actually gigantic space stations with [[DidYouJustPunchOutCthulhu anti-star god weapons]]. There's also the implication that their "gods" are actually the ancient [[{{Precursors}} Old Ones]].
* ''TabletopGame/ForgottenRealms'' has several, including the incident where elves imprisoned three fiends, but the warning became a legend, then a fairy tale, then CurseEscapeClause was fulfilled and three very pissed off nycaloths were released, so they assembled The Army of Darkness which eventually crushed Myth Drannor. For that matter, City of Song itself, despite being relatively recent, became semi-mythological, or at least unpleasant details tend to be left out -- that keying selective spells to attack "allied" races being outlawed after some precedents, or that Cormanthyr ended up ruled by a council because Srinshee was exasperated enough to claim its throne by [[OnlyTheChosenMayWield blade-rite]] only to give a public speech outlining her disgust over their behaviour and teleport away.

[[/folder]]

[[folder: Video Games ]]

* Lampshaded in ''VideoGame/TheLegendOfZeldaSkywardSword''. Gaepora is giving exposition via the legend that has been handed down through the ages in Skyloft, as instructions on what Link is supposed to do. Then Fi, who was actually around when the legend was written, comments that oral tradition is not a very efficient method of data preservation, and proceeds to recite the same legend, but far more detailed.
** This trope is also used to explain the apparent plot holes in the various games' backstories: most of the games take place hundreds or even thousands of years apart, and history has been muddled a bit since the actual events occured.
* This is present in the game ''ShiningForce''. The game opens with a tale of the defeat of Dark Dragon, who vowed to return in 1,000 years. The opening then states that after ten centuries of peace, Dark Dragon was "forgotten by all".
** The gods are perhaps a straighter example [[spoiler:since they're really just regular people who developed highly advanced technology in ages past - most of which has been forgotten or lost even by their descendants]].
* The final scene of ''VideoGame/MassEffect3'' implies that this will ultimately happen to Shepard, since the scene shows a grandparent telling a child the story of "The Shepard." This is also used to explain the various differences caused by the player's choices through their individual playthrough.
* In ''VideoGame/TheElderScrollsVSkyrim'' the events of ''Oblivion'' took place several centuries ago. Due to political upheavals and the Altmer falsely claiming credit for ending the Oblivion Crisis, the exact details of the Champion of Cyrodiil's actions have become confused.
* ''Videogame/DarkSoulsII'' takes place long after the events of ''Videogame/DarkSouls''. The Chosen Undead's journey to determine the fate of the Age of Fire is nothing but a faded memory. This is reflected in the item descriptions for certain items that were in the first game. While some of the lore is consistent, all of the names of the major characters in the first game have been forgotten.

[[/folder]]

[[folder: Web Comics ]]

* ''Webcomic/SluggyFreelance'' has the Gods of Mokhadun, who all withdraw from the mortal realm after a mortal/divine love affair ends up killing several of them, destroying Mokhadun, and nearly ending the world. The survivors slowly forget the truth of the gods as they fade into myth; some, such as the deceased and exiled, are forgotten altogether, while Father Time's name is lost, Dunnuloa, said in myth to now dwell in the moon, becomes Lunoa and then becomes Basphomy, Patron of Halloween (and is then forgotten as she gets replaced by The Pumpkin King), Krig Gaul the God of Joy becomes Kringle, Patron of Kristmas, and female Rana, said in myth to now dwell in the sun, becomes the male Egyptian sun god Ra.

[[/folder]]

[[folder: Western Animation ]]

* The events of ''Franchise/TransformersGeneration1'' have faded into myth during the ''WesternAnimation/BeastWars'' and ''WesternAnimation/BeastMachines'' era. When [[TheStarscream Starscream]] returned by possessing Waspinator, he fooled Megatron into believing that [[ChronicBackstabbingDisorder Starscream]] was a loyal Decepticon who fell in battle against Unicron. Blackarachnia knew enough history (Galvatron killed Starscream for betraying him) to call him out on his lie.
