Planète was a French magazine of “Fantastic realism” which ran throughout the 1960s. I’ve never seen a copy but sight of the immediately recognisable covers has always fascinated because this was the magazine established in the wake of the huge success of The Morning of the Magicians (1960), a unique “Introduction to Fantastic Realism” by Louis Pauwels and Jacques Bergier. Rather than enthuse at length about The Morning of the Magicians I’ll simply point you to this piece by the late RT Gault from his now-defunct website.
Pauwels and Bergier’s book was oft-imitated but never equalled during the 1970s. Where later authors such as Erich von Däniken tended to plough a single, narrow furrow, Pauwels and Bergier leapt breathlessly from one subject to another: alchemy in the 20th century, Forteana, a lengthy examination of the occult preoccupations of the Third Reich, speculations about nuclear physics, speculations about biological mutation, Hollow Earth theories, etc, etc, all the time dropping quotes from HP Lovecraft, Arthur Machen and Albert Einstein. It’s a very heady mix which is great fun to read even though there’s nothing like a solid argument that comes out of it all.
Planète continued the blend of Futurology and fringe philosophy while using the magazine format to print translations of science fiction and fantasy stories; among other things it was notable for bringing the stories of Jorge Luis Borges to a wider audience in France. The magazine’s name may have been science fictional but the magazine as a whole is closer to the kind of borderline sf/art magazine that New Worlds became under Michael Moorcock’s editorship in the late 1960s. I’ve never seen Moorcock or anyone connected with New Worlds mention Planète but the covers at least pre-empt the style adopted by New Worlds during its large-format run: consistently bold typography and imagery that only obliquely relates to the contents.
