''Cija--Princess of Atlantis--fights for her life in a savage world of lust and violence[.]''

--the blurb on the Paperback Library edition of ''Atlan''

''Atlan'' (also known as ''The Atlan Saga'', originally published in the 1960s through the 1970s) is a series of British fantasy novels written by Jane Gaskell. The books take place in a prehistoric civilization--"before the continents had changed," state some of the back cover descriptions. Gaskell's intent seems to have been to combine every prehistoric myth into one lengthy narrative. The primary thesis of the novels is that they tell the story of how the human race ''really'' came to be. For instance, Gaskell explains in the introduction to the first novel that the legendary Mesoamerican country Aztlan is synonymous with the lost continent of Atlantis (hence the title of the series), among other alternative historical tidbits.

Princess Cija (pronounced "key-a"), the heroine, begins as a naive seventeen-year-old kept sheltered in her royal tower. Her mother, known only as the Dictatress, has maintained her daughter's ignorance because of a prophecy that Cija would destroy the kingdom if she ever left her tower. As a result, Cija believes that the male half of the human race has gone extinct, that female humans reproduce through laying eggs, and that there is no land war going on around her. When the half-man, half-reptile General Zerd invades Cija's home country, the Dictatress offers him her daughter in marriage after instructing her to kill him. Zerd takes Cija prisoner, and there begin some intercontinental adventures that change the princess irrevocably....

Flawed and obscure though it is, ''Atlan'' is notable for its originality. It's also probably the only series that can be accurately described as a Gothic JungleOpera, influenced as it is by Mervyn Peake's ''Literature/{{Gormenghast}}'', the works of Rider Haggard, the ''Tarzan'' series, old Gothic novels, and obsolete anthropological studies. If nothing else, this series probably represents the dying days of the pre-''Literature/LordOfTheRings''-influenced fantasy genre, which would never revisit the "elder Earth" theme in quite the same way. Tanith Lee has cited this series as an influence on her work (see ''The Storm Lord''), and Gene Wolfe's ''Literature/BookOfTheNewSun'' takes some rather obvious cues from Jane Gaskell's magnum opus.

In order, the books are:

* ''The Serpent''
* ''The Dragon''
* ''Atlan''
* ''The City''
* ''Some Summer Lands''

''The Serpent'' and ''The Dragon'' were originally published as one novel before they were DividedForPublication.
These novels provide examples of:
* AbusiveParents: Most of the mothers Cija encounters insult their children to their faces at the very least. She herself is the only wholly loving mother in the entire series, and even then, sometimes her best intentions fail.
* ActionGirl: Cija has her moments in ''The Serpent'' and ''The Dragon'', such as aiding a camp of soldiers in defending themselves from an ambush.
* ActionSurvivor: Cija and Seka spend most of the series clinging desperately to their lives. Seka is all the more remarkable for being a small child.
* AllMenAreRapists: Not literally ''every'' man in the series is a rapist, but Cija's suspicions of the men she meets on her travels are often well-founded. In fact, ''most'' of the men in the series are sexually abusive--not because they're male, but because the nature of Cija's adventures tends to confront her with bandits, mercenaries, and other brutal, immoral men. Gaskell usually spares the reader the details, however.
* AnachronismStew: One might think that this series takes place in the Mesozoic era, given the descriptions of people riding dinosaurs. However, this impossible coexistence is merely one of several preposterous elements in the series. All evidence indicates that the events of the series predate life on Earth as we know it. [[note]]For that matter, the timeline in this series is jumbled and bizarre. Not only do dinosaurs inhabit Earth at the same time as the human race, but some of the reference books cited in ''The Serpent'' and ''The Dragon'' describe, variously, events that occurred in the Cambrian period, ancient Greece, and pre-Columbian America.[[/note]]
** At one point in ''Atlan'', a character uses the word "lesbian," even though the novel is set several million years before the existence of the isle of Lesbos. Similarly, the first book contains the words "homosexual" and "sublimating." These linguistic anachronisms may be excused by the author's note in ''The Serpent'', which explains that the manuscript has been "translated" into "the language of our day."
* {{Atlantis}}: Obviously.
* AtlantisIsBoring: Averted. Cija travels to Atlan through a glass undersea tunnel and sees all kinds of attention-grabbing fauna there.
* Myth/AztecMythology: A major influence on the series, as was Theosophy.
* BestialityIsDepraved: A surprising amount of sex between humans and animals is referred to, though not shown, throughout the series. More oddly, most of the characters who mention it ''don't'' seem to consider it exceptionally perverted, as unusual as they may find it.
* BittersweetEnding: The conclusion of the final novel.
* [[GreenSkinnedSpaceBabe Blue-Skinned Space Babe]]: The Atlanteans are blue-skinned ''Earth'' people, and Cija describes herself and her serving women as having "blue-white" legs.
** Terez, the dancing girl in ''The Serpent'' and Smahil's ''other'' mistress in ''The Dragon'', has golden skin.
* BrotherSisterIncest: Of all the men Cija has sex with, consensually or not, her half-brother Smahil comes the closest to being her true love...or so she thinks initially.
* CampGay: In ''The Serpent'', Cija encounters Lel, an effeminate boy who describes himself as "wishing [he] had been born a girl." [[TransEqualsGay Before the reader can assume that Gaskell included an impressively early example of a transsexual character in a fantasy novel, Lel appears as the catamite to a decadent aristocrat from a court full of "woman-hating men."]]
* ClassicalAntihero: Cija begins as a pitifully weak heroine and improves as she grows older.
* CombatTentacles: A tentacled creature attacks Cija during a river ride. [[NothingIsScarier All we see of the monster is the tentacles]], but Cija imagines its "friends and relations" lurking below.
* ContemptibleCover: Several editions of the books have blatantly sexual or otherwise unappealing covers. The Orbit editions, the first of which is pictured above, invert the trope with lush landscape covers that present the narrative as ''more'' tasteful than it is. (The covers of the Pocket editions, though not the most dignified, portray the contents of the books more accurately than any others.)
* DamselInDistress and TheIngenue: Cija gets abducted multiple times in every book.
* DinosaursAreDragons: The narration refers to all giant reptiles as "dinosaurs," which it uses interchangeably with "dragons." This terminology includes monstrously huge serpents.
* DisappearedDad: Cija grew up without a father, but she eventually finds him. The results are not heartwarming.
* EldritchLocation: Ancient Atlan is described in-universe as if it were sentient and waiting to take vengeance on those who invaded it. Guess what happens?
* ForegoneConclusion: After all, it ''is'' the [[EverybodysDeadDave story of Atlantis]].
* GoodGirlsAvoidAbortion: Cija wants to keep her [[spoiler:half-human]] fetus at first, but her mother urges her to abort it. [[spoiler:And then Smahil ''forces'' her to get an abortion.]]
* GratuitousRape: Every now and then.
* HalfHumanHybrid: General Zerd. His daughter Seka is three-fourths human. [[spoiler:Cija's daughter Despair is half-ape.]]
* HumanSacrifice: The temple where Cija's father lives and schemes practices human sacrifice regularly and posts the victims' heads on stakes outside.
* HumanoidAbomination: The Changeless, whom Cija thinks are legendary...at first.
* HungryJungle: The jungle is full of monsters, bandits, and murderers--and most of the series takes place in it.
* InfantImmortality: Possibly averted in ''Atlan'', in which Cija's son Nal wanders off in the middle of an earthquake.
* InterspeciesRomance: Zerd was born by a reptile mother to a human father. Zerd's marriage to Cija also counts, despite the lack of actual romance in their relationship.
** In ''The City'', Cija returns to her old tower and finds that apes have overrun it. Shortly thereafter, she becomes a bull ape's paramour. He goes so far as to [[HalfHumanHybrid impregnate her]], which she strangely welcomes. In fact, she loves him more than any of the actual men she meets.
** When Cija finds her father in a temple, she notices that he has married an alligator.
* JungleOpera: ''The Serpent'', ''The Dragon'', and ''The City'' in particular, but all the books take place at least partly in a jungle.
* JustBeforeTheEnd: See ForegoneConclusion. [[spoiler:In this case, however, the end is a new beginning.]]
* LostWorld: The setting as a whole qualifies (being lost temporally in the same way as Middle-Earth, not just physically), but the titular island of Atlan (short for Atlantis) merits this term especially, being shielded by a force field and accessible only via an underwater tunnel.
* MadScientist: The creepy old man who secretly lives in Zerd's Atlan castle is one--and he doesn't just ''appear'' to be murderously insane, either.
* MaleToFemaleUniversalAdaptor
* MarsNeedsWomen: Cija's aforementioned non- and semi-human lovers count, but there are equal-opportunity instances as well.
* MaybeMagicMaybeMundane: Is Cija actually related to the nebulous deities of her country's pantheon, or is she just full of herself? Her inadequacy may seem to suggest the latter, but the interspecies reproduction throughout the series implies that the laws of nature in this prehistory are not what they are now. (That said, witchcraft is a crime in Atlan.)
* MisplacedWildlife: Gaskell's introduction to ''The Serpent'' states explicitly that the flightless birds ridden by the Northern Army are ''Diatryma''...which lived in North America, not South America. See also StockDinosaurs below.
* NewWeird: A very early example, looking forward to the aforementioned ''Literature/BookOfTheNewSun'' and backward to [[Litertature/{{Gormenghast}} Mervyn Peake]], Creator/ClarkAshtonSmith, and, to a lesser extent, Creator/HPLovecraft (with possibly some non-weird Burroughsian influence).
* NiceJobBreakingItHero: Cija sics her carnivorous riding bird on a man who sexually abused a young girl. The bird succeeds in killing the man, but at a terrible price....
* NoWomansLand: One of the countries Cija and Seka visit in ''Some Summer Lands'' has shades of cultural misogyny. Girls and women are not counted in population records, and mothers refer to all their children, regardless of their sex, with masculine pronouns--feminine pronouns themselves are considered insults. Of course, the world abounds with violent men no matter where Cija goes.
* ObfuscatingStupidity: The Dictatress urges Cija to use this tactic on her enemies. Problematically, Cija ''is'' genuinely stupid at first.
* OneGenderRace: As a child, Cija was taught that the human race consisted entirely of women who reproduced by laying eggs. Learning that the storybook creatures called men actually exist surprises her.
* PhysicalGod: Cija believes that she is directly related to divinity and insists on referring to herself as a goddess.
* RagnarokProofing: The first book is supposedly a translation of Cija's diary, which must have [[spoiler:survived an apocalypse millions of years ago]].
* RoyalsWhoActuallyDoSomething
* SexSlave: After running from Zerd's castle, Cija gets kidnapped and sold into slavery at a brothel, but she escapes before being forced into any more sex acts.
* SilentSnarker: Cija's daughter Seka is mute. She also narrates ''Some Summer Lands'' in a far more perceptive and sarcastic manner than her mother could manage.
* SlidingScaleOfIdealismVersusCynicism: Toward the cynical end--the series has a despairing tone all throughout.
* StockDinosaurs: The dinosaurs (excepting the giant reptiles that are ''not'' dinosaurs despite being labeled as such) identified in the series are the ''T. rex'' and some kind of sauropod. However, the trope is averted with the Northern Army's mounts, which are specified as ''[[http://en.wikipedia.org/wiki/Gastornis Diatryma]]'' but should probably be ''[[http://en.wikipedia.org/wiki/Phorusrhacidae Phorusrhacidae]]''.
* SweetPollyOliver: Cija travels in drag in the second half of ''The Serpent''.
* TempleOfDoom: In ''The City'', Cija and the two children she befriends get lost in an underground labyrinth, where they are pursued by men who intend to feed them to alligators. More literally, Cija's father heads a temple in which he plots the downfall of the Dictatress, Cija's mother and the kingdom's secular ruler.
* YourCheatingHeart: When Zerd isn't invading and plundering foreign lands, he's flirting with, sleeping with, and, in a few cases, marrying other women behind his wife's back. Note that Cija is his ''third'' wife, and he never got a divorce from either of the other princesses he married.
