« La matière en était gélatineuse et peu consistante; elle se décomposa, au bout de quelques heures, en un liquide rose et gluant, d’une odeur insupportable.* » — Jean Ray, Dans les marais du Fenn
Aw, good old muck monsters…
Perhaps the first to emerge, at least in the English language, was Theodore Sturgeon’s “It”, published in Unknown’s August, 1940 issue, whose title page warned: “IT wasn’t vicious, IT was simply curious — and very horribly deadly!“
But IT was preceded, by some years, by Raymond Marie de Kremer alias Jean Ray’s superb Dans les marais du Fenn (« In the Fenn Marshes »), first published in the Belgian literary magazine L’ami du livre’s issue of November 1st, 1923! A handful of Ray stories (often published under his alternate nom de plume, “John Flanders”) were published in US pulps, including the legendary Weird Tales, but “Dans les marais…” appears to have somehow, to this day, remained untranslated to English.
This is Supernatural Thrillers no. 1 (December, 1972, Marvel), an adaptation by Roy Thomas, Marie Severin and Frank Giacoia. Cover by Jimmy “Profa” Steranko.
*« Its matter was gelatinous and insubstantial; it decomposed, within a few hours, into a viscous pink liquid of unbearable odour. »
