Children of steam and scalded rock, a story you have to tell,
Writ in the glare of sunshine bright,
Sculptured and etched in marble white,
Illuminated in colors bold,
Richer than ever parchment old,
Children of steam and scalded rock, what is the story you have to tell?
Our legends are old, of greater age than the mountains round about.
We have kept our secrets epochs long,
They are not to be read by the passing throng.
It is nothing to us what men may say.
If they wish our story the price they must pay
In hard brain work, ere the tales are told. We challenge mankind to draw them out.
Children of steam and scalded rock, your challenge must rest for the present age.
I have scarcely broken the outer crust
That covers the greater truth, but I trust
Some man will follow and therein find
Knowledge, that to the Present shall bind
The Past with cords wherein entwine
Threads of the perfect truth, divine.
Children of steam and scalded rock, some man to come will accept thy gage.
A poem by Bradley Moore Davis, University of Chicago, published
in his 1897 paper in the journal Science and describing for the first time
microbes present in Yellowstone hot springs.
This book will tell you the story of those who “accept thy gage.”

Prologue
The souls of the damned writhe in pain in the cauldrons of hell. Life appears
to be incompatible with the flames of Satan. Plunge a crab into a pot of boil-
ing water and it comes out cooked— but dead. Plunge your own finger in and
the pain is unbearable. It’s indisputable: even if we like heat, preferably in the
shade on a beach, we must stay within the limits of what is reasonable. And
yet, in the last thirty years, scientists have discovered microbes that thrive
in temperatures that exceed those of the hottest deserts in the world. These
creatures, whose existence is revealed only under a microscope, live in places
that humans have equated with the gateway to hell. They are found in Solfa-
tara, near Naples, Italy, which the ancient Greeks believed was the home of
Charon, whose boat transported the souls of the dead on their final voyage,
and in Iceland, the island where Jules Verne’s heroes journeyed to the center
of the earth. These microscopic single- celled organisms have telling names,
such as Acidianus infernus, which likes both “infernal” temperatures and ex-
treme acidity, or Pyrococcus abyssi, the “burning shell of the abyss.” These
are thermophile microbes (from the Greek therme, “heat,” and phylos, “that
which loves”). The most infernal among them have been baptized as “hyper-
thermophile” microbes because these amazing beings, which love the highest
temperatures, flourish only between 80 and 110°C and freeze below 70°C.
These microbes from hell, whose existence was unknown to scientists
until relatively recently, are today at the heart of particularly active research.
International meetings have been devoted to them every two years since 1990,
bringing together first dozens, then hundreds, of scientists from throughout
the world. Why such passion for living beings so different from us? Some
evolutionists believe that thermophile and hyperthermophile microbes can
teach us a lot about the way life appeared on our planet, at a time when it
Description:At the close of the 1970s, the two-domain classification scheme long used by most biologists—prokaryotes versus eukaryotes—was upended by the discovery of an entirely new group of organisms: archaea. Initially thought to be bacteria, these single-celled microbes—many of which were first found
