I recently wrote about Close to Critical, a 1950s novel that I first read in the late 1960s. Some time after that I read City of the Chash and its sequel, Servants of the Wankh  (in Dutch, it wasn’t until the late 80s that I started reading mainly in English), the first two volumes in the Planet of Adventure series. It took me some time to convince myself to read the books: the blurb on the first one said that it was “brilliant and hallucinating” (‘briljant en waanzinnig’) and that somehow put me off as it sounded like some experimental prose that I had tried (and failed) to read. However, I was a voracious reader (during school vacations 2 or sometimes even 3 books per day) and ever since I had read Robert Heinlein‘s Orphans of the Sky while at an astronomy camp in the summer of 1968, I did not read anything but science fiction. So at some point, I had actually read all science fiction books that our local library offered and found myself forced, despite the off-putting “maniacal” and the fact that I had never heard of the author (Jack Vance, 1916-2013), to give these books a try anyway. That was a fateful decision, leading to a lot of joy (reading many more wonderful Vance novels and stories) and a lot of anguish (impatiently waiting for the next volumes in the tetralogy to appear, which took more than a year – something close to eternity when you’re 16 years old…).

Where Hal Clement had shown me the wonderful and amazing worlds that science fiction writers can imagine, Jack Vance blew me away with the strange and alien cultures that his mind produced. Some of his most alien cultures were actually human… In fact, as I learned later, the Planet of Adventure series is a somewhat atypical example of Vance’s work, which most often describes human worlds and cultures and much less often includes alien species. Well, Tschai, the world on which these novels are situated, contains not just one, but at least four separate and very different alien species: the Chash (which come in three very distinct varieties: the decadent Old Chash, the more dynamic Blue Chash, and the barbaric Green Chash), the Wankh (in later editions called “Wannek”), the Dirdir, and the indigenous Pnume. There’s a fifth alien species, the Phung, but it remains unclear whether this is really a separate species or an insane variant of the Pnume. When an explorer from Earth, Adam Reith, crashes on Tschai, he finds to his bewilderment that it is also inhabited by humans, in an even more bewildering diversity of peoples, races, tribes, and varieties. These humans are the descendants of Neanderthals and other humans taken from Earth by some of these aliens in prehistoric times. Each one of the four alien species has a specialized variety of humans to serve them (with the interesting exception of the Wankhmen) and that have evolved to resemble them physically (the Dirdirmen, for example) or mentally (the Pnumekin). The other peoples of Tschai are descendants of members of these client races that for some reason or another were expelled from their communities.

Over the years and decades, I re-read these novels several times. So much so, that I actually could point out on a map of Tschai the different places visited by Reith in sequence. I don’t recall when I read my old Dutch copy of the tetralogy for the last, umpteenth, time, but recently I decided that I wanted to read the novels yet again, but this time in their original English. I wasn’t disappointed. Within a week of the arrival of my new copy, I had finished it (it was a busy week, so I could not read as much as I wanted…). The books, I am happy to report, have withstood the ravages of time quite well and are still a fascinating read.

The narrative follows Reith, who tries to obtain a spaceship to return to Earth to warn humanity for the threat that these alien species represent. His quest takes him all over Tschai, which provided Vance with the canvas on which to paint dozens of different human cultures, each with its own peculiar habits and strange religious beliefs. Vance is not a writer who waxes philosophical about how such customs, rituals, and religions emerge or how a culture gets established. However, when reading a book like Planet of Adventure, I really cannot imagine that someone would only read this as an adventure novel and nothing more. One simply is forced to wonder how all this came about. In some cases, this is obvious. The Dirdirmen, for example, believe that they originate from a Primeval Egg, which lay partly in the sun, partly in the shade on the Dirdir homeworld. When it hatched, the Dirdir emerged from the sunny side and the Dirdirmen from the shaded side. As one of Reith’s travel companions, the Dirdirman Ankhe at afram Anacho says: “They are Sun, we are Shade… The Dirdir are the highest form of cosmic live; Dirdirmen can only emulate and this we do, with pride”. To approach this ideal Dirdir form as much as possible, the Dirdirmen have practiced selective breeding for many millennia, supplemented with surgery and the use of artificial body parts. The Dirdir, in turn, mostly seem to barely acknowledge the existence of the Dirdirmen. Nevertheless, it appears clear that the origin of this creation story must be the Dirdir themselves, who have made it up to keep the Dirdirmen in their place as useful servants.

The books are filled to the brim with inventive concepts and ideas. For example, on Tschai money does grow, albeit subterranean, not on trees. One might expect that this would make it easy to become rich. Not so. Money remains scarce, because it only grows in one particular region and the Dirdir use this as their hunting ground, where they return to their pre-civilized feral state and hunt the humans that search for money, roasting and eating their prey. Fascinating and puzzling are the decadent Yao, where individuals have a plethora of personal names, each to be used only in precisely defined circumstances that are almost impossible to grasp for outsiders. Some rituals look silly to us, like the sect that considers the act of ingesting nourishment to be something intrinsically personal, not to be performed in public, much like we think about sex. My favorites in the book are the mysterious Pnume, with a recorded history of millions of years. Although the fourth volume of the series plays almost exclusively in their underground realm (somehow, “subterranean” seems out of place and “subtschaian” is awkward), they remain at the end only slightly less mysterious than before.

When reading these descriptions of wonderful, mysterious, silly rituals, cultures, and religions, I find it impossible not to reflect on how real-world religions, rituals, and cultures came about and wonder whether some of our beliefs and habits have perhaps a similar, almost trivial, origin, where someone or some group made up something to further some selfish goal. That, of course, is what good science fiction does: it makes you think.

In short, these books have remained as fascinating as when I read them for the first time, almost half a century ago. Of course, knowing these books so well, by now the surprise is gone for me, although the sense of wonder remains. So I envy you, if you don’t know Tschai yet, because there is no equivalent to the sensation of discovery that you get when you read these books for the first time.
