Terry Pratchett’s Discworld novels comprise among the most great, good, and weird fantasy satire ever written. Even after a long time of being a fan, I am rediscovering new bizarre particulars each time I choose up a Discworld guide, whether or not it is my fifth time studying it or my fiftieth, and I am keen on how deeply intertwined the lore is. Sadly, with Pratchett’s passing years in the past, it looks like one of many best mysteries on the Disc – one which’s been theorized about since Discworld‘s very first books – will go unanswered.
The World Turtle Great A’Tuin, upon whose again the Disc rotates, actually serves as the inspiration of the Discworld, but so little tangible details about the creature and its species is ever detailed within the books. We do not even know the intercourse of Nice A’Tuin – a element that lots of the Disc’s more narratively central characters are deeply involved about, contemplating that whether or not A’Tuin is a prime or a backside might effectively have disastrous penalties for the Disc (and the elephants!) perched delicately upon its again.

Whereas lots of the trivialities of the Disc are explored or defined all through the primary sequence, or within the Science of Discworld aspect books that Pratchett co-wrote with science writers Ian Stewart and Jack Cohen, the small print of Nice A’Tuin’s reproductive biology are by no means revealed, solely teased. Actually, even the element that the Disc is balanced atop Nice A’Tuin is not essentially taken as a tough truth by its inhabitants; Omnism, the widespread faith that worships the Nice God Om, really believes the Disc to be spherical, very like our personal world.
It is fairly tough to present an intensive veterinary examination to a turtle that’s roughly 10,000 miles lengthy and floating by means of a vacuum.
Omnism is not the one purpose why nobody is aware of the intercourse of Nice A’Tuin, although. The larger concern is that it is fairly tough to present an intensive veterinary examination to a turtle that’s roughly 10,000 miles lengthy and floating by means of a vacuum. Furthermore, whereas real-world sea turtles exhibit comparatively minor sexual dimorphism, often associated to the scale of the tail or the presence of greedy claws on the forelimbs, these are small particulars that depend on with the ability to evaluate A’Tuin to a different member of its species.

One Underrated Discworld Detail Is A Breath Of Fresh Air Compared To Other Fantasy Books
Terry Pratchett’s Discworld is a large and sprawling set of books with one refreshing element that units it other than different fantasy sequence.
Such an examination was the purpose of the nation of Krull, who despatched a capsule over the Disc’s edge on the finish of The Color of Magic in hopes of getting a solution. Sadly, because the capsule wound up containing the long-suffering wizard Rincewind and his companion Twoflower as a substitute of the assigned chelonauts, no scientific observations of word have been made, and Rincewind and Twoflower have been rescued from the destiny of drifting endlessly by means of area at first of The Mild Implausible.
The Eggs In The Mild Implausible Make A Convincing Case That Nice A’Tuin Is Feminine
With Little Dependable Information On A World Turtle’s Habits, It is A Query Of Inference
Whereas not one of the Disc’s inhabitants in The Mild Implausible or in any other case handle to get a glimpse of Nice A’Tuin’s reproductive anatomy – which would not have helped anyway, since turtles hold their fiddly bits inside their cloaca, no matter intercourse – there may be at the very least one element in that guide that may very well be a touch. On the finish of The Mild Implausible, as A’Tuin approaches the good crimson star that the Disc thinks is an omen of doom, the star’s eight ominous moons crack aside to disclose eight child World Turtles, every with a Disc of their very own.
The Octavo, a grimoire saved comparatively contained at Ankh-Morpork’s Unseen College, is believed by the wizards there to be essentially the most highly effective spellbooks in all of creation. This can be true, for the reason that operate of the spells appears to be to assist the World Turtle infants hatch, and few issues are as highly effective as the flexibility to deliver life into the world.
Provided that till that time, A’Tuin was the one World Turtle mentioned within the books, it could be affordable to imagine that these hatchlings belonged to it ultimately, and that A’Tuin is their mom. In any case, it is A’Tuin’s presence, and the spells from the Octavo, that triggers their hatching; but that assumption does not really maintain as much as scrutiny, because it depends on a good variety of different assumptions, and any wizard price their pointy hat would level out that correlation doesn’t, in actual fact, indicate causation.

Correlation Does Not Suggest Causation, Even With Regard To Large Magical Area-dwelling Reptiles
Though A’Tuin’s presence leads to the eggs hatching, there isn’t a indication that A’Tuin laid the eggs within the first place, and whereas the hatchlings do observe A’Tuin away from the crimson star, they finally go on their very own approach. It is simply as doubtless that A’Tuin was pushed by intuition (and even magical compulsion) to be current for the hatching, relatively than any particular maternal connection.

Out of all of Terry Pratchett’s unbelievable and unforgettable forged of characters, these are essentially the most enduring, compelling, and sometimes hilarious.
Neither is there any correlating conduct we are able to assume based mostly on our personal world’s sea turtles, as their hatchlings must fend for themselves as quickly as they emerge from their eggs. Whereas A’Tuin is proven affectionately greeting the infants within the BBC miniseries adaptation of The Color of Magic, this is not a element current within the authentic textual content. In the long run, Discworld‘s Nice A’Tuin and its reproductive cycle stay a cosmic thriller that may by no means be solved – though I prefer to suppose Terry Pratchett needed it that approach.
