Pellucidar

Geography

In Burroughs' concept, the Earth is a hollow shell with Pellucidar as the internal surface of that shell. Pellucidar is accessible to the surface world via a polar opening allowing passage between the inner and outer worlds through which a rigid airship visits in the fourth book of the series. Although the inner surface of the Earth has a smaller total area than the outer, Pellucidar actually has a greater land area, as its continents mirror the surface world's oceans and its oceans mirror the surface continents.

A peculiarity of Pellucidar's geography is that due to the concave curvature of its surface there is no horizon; the further distant something is, the higher it appears to be, until it is finally lost in the atmospheric haze.

Pellucidar is lit by a miniature Sun suspended at the center of the hollow sphere, so it is perpetually overhead giving a time sensation of eternal noon wherever one is in Pellucidar. The sole exception is the region directly under a tiny geostationary Moon of the internal sun; that region as a result is under a perpetual eclipse and is known as the Land of Awful Shadow. This moon has its own plant life and (presumably) animal life, and hence either has its own atmosphere or shares that of Pellucidar. The miniature sun never changes in brightness, and never sets; so with no night or seasonal progression, the natives have little concept of time. The events of the series suggest that time is elastic, passing at different rates in different areas of Pellucidar and varying even in single locales. Also, several characters from the outer world who have lived a long time in Pellucidar seem to age slowly and exhibit considerable longevity. This is known through their interactions with people of the outer world where time remains fixed.

Culture

Pellucidar is populated by primitive people and prehistoric creatures, notably dinosaurs. The region in which Innes and Perry initially find themselves is ruled by the cities of the Mahars, intelligent flying reptiles resembling Rhamphorhynchus with dangerous psychic powers, who keep the local tribelets of Stone Age human beings in subjugation. Innes and Perry eventually unite the tribes to overthrow the Mahars' domain and establish a human "Empire of Pellucidar" in its place.

While the Mahars are the dominant species in the Pellucidar novels, they seem confined to their handful of cities. Before their overthrow they use the Sagoths (a race of gorilla-men who speak the same language as Tarzan's apes) to enforce their rule over the human tribes within the area which they rule. Though Burrough's novels suggest that the Mahar realm is limited to one relatively small area of the inner world, John Eric Holmes' authorized sequel Mahars of Pellucidar indicates there are other areas of Mahar domination.

Within and outside the Mahars' domain are scattered independent human cultures, most of them at the stone age level of development. Technically more advanced exceptions include the Korsars (corsairs), a maritime raiding society descended from surface-world pirates, and the Xexots, an indigenous Bronze Age civilization. All or most of the human inhabitants of Pellucidar share a common world-wide language.

Pellucidar wildlife

Various animals reside in Pellucidar. Some of them are primarily prehistoric creatures that are extinct on the outer world while others were created by Edgar Rice Burroughs. They are listed below by outer world name (if known), Pellucidarian name (if known), and the book in which they first appear, along with any relevant comments.

Races and tribes

Pellucidar also harbors enclaves of various non-human or semi-human races and tribes. Among the known races and tribes in Pellucidar are:

Sequels by John Eric Holmes

John Eric Holmes's Mahars of Pellucidar was a sequel to Burroughs' Pellucidar novels authorized by the Burroughs estate. Publication of Holmes' follow-up novel, Red Axe of Pellucidar, reportedly ready for print in 1980, was reportedly blocked by the estate, and only saw print much later in a limited private edition.

1. Mahars of Pellucidar (1976)
2. Red Axe of Pellucidar (1993)

Tarzan: The Epic Adventures

In the 1996 novel Tarzan: The Epic Adventures by R. A. Salvatore, Pellucidar is featured in the later part of the story. The book is based on the teleplay for the TV pilot of the series Tarzan: The Epic Adventures by Burt Armus. The story is inspired by the Return of Tarzan and Tarzan at the Earth's Core.

In other media

When DC Comics had the rights to the Burroughs properties in the early 70s, they did a comic book adaptation of At the Earth's Core that ran in Korak, Son of Tarzan #46, then moved to Weird Worlds #1-5, then continued with an adaptation of Pellucidar in #6-7. Another Pellucidar story appeared in Tarzan Family #66. Dark Horse Comics will reprint this in trade paperback in 2017.

Pellucidar has appeared in one movie adaptation. The first novel was filmed as At the Earth's Core (1976), directed by Kevin Connor and starring Doug McClure as David Innes and Peter Cushing as Abner Perry.

Pellucidar appears in the Tarzan, Lord of the Jungle episode "Tarzan at the Earth's Core."

The 1996 pilot to the TV series Tarzan: The Epic Adventures also features Pellucidar, as well as the character Jana from the book Tarzan at the Earth's Core. This story also features a race of Mahars that are able to transform into humanoid form.

Pellucidar appears in a few episodes of the Disney cartoon series The Legend of Tarzan, loosely inspired by Tarzan at the Earth's Core. In the show however, Pellucidar is merely described as being a region below Africa where dinosaurs still live. None of the characteristics of it described in the novels are seen.

Pellucidar is revisited by Tarzan and is the central location of the Dark Horse Comics crossover Tarzan vs. Predator at the Earth's Core where Tarzan faces off against the alien Predator species in Pellucidar.

Influence

A tribute story, Maureen Birnbaum at the Earth's Core, appeared in Maureen Birnbaum, Barbarian Swordsperson.

Pellucidar was the major inspiration for Lin Carter's Zanthodon novels of the late 1970s and early 1980s, set in the vast cavern of Zanthodon beneath the Sahara Desert.

The Hollow Earth milieu of Skartaris in the Warlord series of comic books by Mike Grell, published from 1976–1989, is essentially a translation of Pellucidar into the graphic medium, with the admixture of magic and elements of the Atlantis myth.

The hollow interior of the Earth seen in the 2008 Asylum film Journey to Middle Earth bears some similarity to Pellucidar, although the film was intended as a film adaptation of a novel by Jules Verne.

The Hollow World of the fictional Dungeons and Dragons setting of Mystara shares many concepts taken from Pellucidar, such as the polar opening(s), the central sun, the floating moon(s) and the primitive cultures living in the internal surface.

In James P. Blaylock's The Digging Leviathan (1984), a pair of rival scientific teams compete to reach Pellucidar; the story concludes before the goal is attained. Blaylock's Zeuglodon revisits the Pellucidar theme, when a group of children attempt to rescue Giles Peach, one of the characters traveling to Pellucidar in The Digging Leviathan.

In John Crowley's Little, Big (1981), a drug named Pellucidar is mentioned and appears to have an exhilarating and even aphrodisiac effect.

During the initial explorations of Lechuguilla Cave in the late 1980s, a chamber was named "Pellucidar" in honor of these stories.

In Philip Jose Farmer's "Riders of the Purple Wage", there is a concept known as "the Pellucidar Breakthrough"

In the Tunnels Series, the Garden of the Second Sun is strongly based on Pellucidar.
