Here's a review I wrote while researching an exhibit for Chicago's
Museum of Science and Industry. I've added rec.arts.sf.written to the
newsgroup line, since I think the story qualifies as eo-SF.  And the
kids there are always asking about SF writers who are also scientists... 

                Johannes Kepler's Voyage to the Moon

Johannes Kepler (1571-1630) was the astronomer who recognized that the
planets move around the Sun in ellipses, a discovery which led
directly to the Newtonian revolution which gave us our present
understanding of the laws of physics.  One of his books, *Somnium* or,
in English, *Dream*, is a fictional voyage to the Moon. 

Duracotus, a native of Iceland, studies astronomy with Tycho Brahe in
Denmark.  When he returns home he discovers that his mother knows far
more about the Moon than Tycho does; she reveals that she is a witch
and converses with demons who regularly travel through space.  (Kepler
studied with Tycho, the greatest astronomical observer of his age, and
his mother was once accused of witchcraft and imprisoned.) 

The witch summons a demon, who explains that travel to the Moon is
possible only when the shadow of the Earth touches it-- that is,
during a lunar eclipse.  "Because the opportunity is so fleeting, we
take few human beings along, and only those who are most devoted to
us.  Some men of this kind, then, we seize as a group and all of us,
pushing from underneath, lift him up into the heavens.  In every
instance the take-off hits him as a severe shock, for he is hurled
just as though he had been shot aloft by gunpowder to sail over
mountains and seas.  For this reason at the outset he must be lulled
to sleep immediately with narcotics and opiates.  His limbs must be
arranged in such a way that his torso will not be torn away from his
buttocks nor his head from his body, but the shock will be distributed
among his individual limbs.  Then a new difficulty follows:  Extreme
cold and impeded breathing. 

"The cold is relieved by a power which we are born with; the
breathing, by applying damp sponges to the nostrils.  After the first
stage of the trip is finished, the passage becomes easier. At that
time we expose their bodies to the open air and remove our hands. 
Their bodies roll themselves up, like spiders, into balls which we
carry along almost entirely by our will alone, so that finally the
bodily mass proceeds toward its destination of its own accord.  But
this onward drive is of very little use to us, because it is too late. 
Hence it is by our will, as I said, that we move the body swiftly
along, and we forge ahead of it from now on lest it suffer any harm by
colliding very hard with the Moon.  When the humans wake up, they
usually complain about an indescribable weariness of all their limbs,
from which they later recover well enough to walk."

In this passage Kepler demonstrates that he understands many of the
problems of space flight:  The need for sudden acceleration, the
dangers of its effect on the body, the cold of space, the gradual
thinning of the atmosphere, the "onward drive" provided as the Moon's
attraction grows.  Some of these he must solve by magic, such as the
demons' lifting power and warmth.  Some he tries to solve by plausible
invention-- arranging the passengers' limbs and applying the damp
sponges-- just as a modern science fiction writer would.  Though
*Somnium* was written in 1609, nearly sixty years before Newton
published a complete theory of gravity, Kepler evidently knew that
planets attracted other massive bodies and that the attraction became
weaker with distance. 

The bulk of the story is concerned with a detailed description of
astronomy as seen from the Moon.  The Earth hangs fixed in the sky,
the Sun arcs slowly overhead every 28 days, eclipses are markedly
different from terrestrial ones, and the behavior of the planets is
somewhat novel.  Kepler evidently delighted in working out the facts
of lunar astronomy, and his whole story is carefully consistent with
the known facts of seventeenth-century science.  He speculates on the
effect of long days and nights on life on the Moon.  Plants and
animals take forms with tough skins to endure the scorching Sun, and
the oceans boil at noon. 

The *Somnium* may be said to be the earliest "hard-science" SF story:
one which hews closely to the line of contemporary science. Amusingly,
Kepler yielded to a temptation that must have afflicted many a
subsequent hard-SF writer-- he added footnotes to explain the
meticulously built scientific background to his story.  The footnotes
run more than four times the length of the story itself!

		Belated Reviews #20:  "Voyages to the Moon"
 
For #20 I'm going to toss in a joker.  "Voyages to the Moon" (****), by 
Marjorie Hope Nicolson, is not a book that long-term readers are generally
familiar with and that newer readers typically slide their eyes over in
used bookstores.  It's relatively hard to find.  It's also not fiction.
It's definitely belated, though:  This 1948 book is a history of space-travel
fiction (particularly, but not exclusively, travels to the moon) before the 
nineteenth century.  Strongly recommended for readers with an interest in
the subject.
 
There is a long but sparse history of fictional space travel stretching
back to classical times, and Nicolson does not ignore it.  The publication
of Galileo's astronomical discoveries in 1610, however, seized the imagination
of Europe, and turned what had been a trickle of such stories into a flood.
People started thinking of the moon and planets as actual places that might
be visited, that might be inhabited.
 
	"There are but three ways of going thither," said a Herald
	in Ben Jonson's 'News from the New World'.  "One is
	Endymion's way, by rapture in sleep, or a dream.  The other
	Menippus's way, by wing, which the poet took.  The third,
	old Empedocles's way; who, when he leapt into Aetna, having
	a dry sear body, and light, the smoke took him, and whift
	him up into the moon."  Jonson harked back to old legend and
	tradition, but John Wilkins, who in 1638 published his
	'Discovery of a New World in the Moon', looked forwared to
	a scientific future much more than back to a literary past.
	"There are," he declared, "four several ways whereby this flying
	in the air hath been, or may be attempted.  Two of them by the
	stregth of other things, and two of them by our own strength.
	1. By spirits, or angels.  2. By the help of fowls.  3. By wings 
	fastened immediately to the body.  4. By a flying chariot."
 
Insofar as serious writers attempt to be in agreement with the best
understanding of their day, it was hardly inconsistent to include spirits
and angels in the list.  Indeed, one of the most significant lunar voyages
of this time was Kepler's "Somnium", published posthumously in 1634, in 
which the astronomer combines a demon-powered trip to the moon with concerns
about gravity, the availability of air, and extremes of temperature.
 
Nicolson uses Wilkins's typology to structure her book thematically.  After
discussing the supernaturally-powered voyages invented by Kepler and others,
she proceeds to cover the topic (too frequently neglected by writers of
modern science fiction :) of bird-powered space flight.  Among the most
significant of these is Francis Godwin's "Man in the Moone: or A Discourse
of a Voyage Thither by Domingo Gonsales", published shortly after Somnium.
Domingo had no intention of visiting the moon when he trained his swans to
carry him.  (Unlike many later fictional inventors who never seemed to allow
for the possibility of failure, Domingo was cautious enough to let a lamb
be the first passenger.)  What he didn't realize was that swans fly to the
moon, come fall, to hibernate.
 
Scientific details play a smaller role in Godwin's tale than in Kepler's.
Like many of his successors, Godwin used the moon primarily as a convenient
place in which to set a Utopia, and much of the book deals with his
description of a society which -- but for certain physical quirks -- might
as well have been located in El Dorado.
 
Flight by the use of artificial wings attracted the most literary interest
before the nineteenth century, since it appeared at the time to offer the 
most realistic prospect for human flight.  Most of the tales Nicolson
discusses in this section, while possibly important to the literary tradition,
do not actually involve space flight.  She has a great deal of fun describing
Restif de la Bretonne's 1781 "La Cecouverte australe Par un Homme-volant, ou 
Le Dedale francais" (call it "The French Daedalus").  This is the tale of
Victorin, who determines to develop usable wings so that he can take his 
Christine away from the society which forbids their love.  Years -- and
about a third of the novel -- go by while he painstakingly studies birds
and insects, builds models, and finally develops working wings.  He locates
an inaccessible mountain, stocks it with the basic necessities (plants,
animals, servants), and finally swoops down and carries Christine off.  (He
seems to have neglected to tell her that he was planning to do this, but
fortunately she proves sympathetic.  They are married by a priest that he
also had the foresight to fly off with.)
 
There are many kinds of chariots, or artificial conveyances one might use.
The best remembered of the seventeenth century are those of Cyrano de
Bergerac, whose 1656 "Histoire Comique des Estats et Empires de la Lune"
(published in translation in 1687 as "The Comical History of the States
and Empires of the Worlds of the Moon and Sun") is distinguished by the
author's insistence on travelling by as many different conveyances as
possible.  His first attempt involved strapping vials of dew to his body.
Since the sun sucks up the dew in the morning, it stood to reason that
he might be carried with it.  This approach actually proved *too* effective
(he broke too many vials in his efforts to keep from overshooting the 
moon), and his second attempt involved the use of fireworks to propel the 
first fictional rocket ship.  His most ambitious vehicle was solar-powered 
in a more modern sense, and used a giant magnifying glass to drive an air 
stream strong enough to sustain space travel.
 
The last chapter is devoted to travels by means which Wilkins overlooked.
The most priceless of these is the 1666 "The Description of a New World,
called The Blazing World", by the Duchess of Newcastle.  The heroine of
this story is kidnaped and taken to the North Pole where all aboard the
ship freeze to death, "the young Lady onely, by the light of her Beauty,
the heat of her youth, and Protection of the Gods, remaining alive."  It
turns out that there is no Northwest passage:  The North Pole provides
passage to another world, instead.  Our intrepid heroine enters this
world, where she eventually becomes its philosopher-empress.  (One gathers 
from Nicolson's description that the book, however delightful its premises, 
is painful to read beyond this point.)
 
The influence of the space romances of the seventeenth and eighteenth
centuries upon modern science fiction is indirect, but profound.  Nicolson
shows how the writers whose works most directly affected modern space-travel
fiction -- writers such as Jules Verne and H.G. Wells -- were in their turn 
influenced by these earlier works.  She deplores, however, the often-
ponderous technological orientation that these writers gave the genre.
 
(This is not to say that the older, non-technological literary traditions
of space flight ever died.  We still get John Carter wishing himself to
Mars, Tycho Bass being blown off the planet, Dr. Dolittle riding to the
moon on a butterfly (one of my personal favorites), and no detectable
reduction in the incidence of out-of-body space-travel.  And we still get
destination worlds which -- beyond serving as locations for whatever
society the author wishes to espouse -- are a lot more like Kansas than
like Oz.)
 
I never though much about the pre-industrial contribution to the genre.
I knew that Daedalus flew with wings, that Cyrano used dew, that Gulliver 
travelled on a flying island, that Thor and Astolfo drove chariots.  If 
I'd though about it, which I didn't, I'd have assumed that these classics 
had had some influence on science fiction, but wouldn't have realized that
these were the tip of the iceberg.  "Voyages to the Moon" is a window upon 
an extensive literature which served as a rich source of inspiration for
the authors we consider the "early" writers of science fiction.

Standard introduction and disclaimer for Belated Reviews follows.

Belated Reviews cover science fiction and fantasy of earlier decades.
They're for newer readers who have wondered about the older titles on the
shelves, or who are interested in what sf/f was like in its younger days.
The emphasis is on helping interested readers identify books to try first, 
not on discussing the books in depth.
 
A general caveat is in order:  Most of the classics of yesteryear have not
aged well.  If you didn't encounter them back when, or in your early teens,
they will probably not give you the unforced pleasure they gave their
original audiences.  You may find yourself having to make allowances for
writing you consider shallow or politics you consider regressive.  When I
name specific titles, I'll often rate them using the following scale:
 
**** Recommended.
***  An old favorite that hasn't aged well, and wouldn't get a good
	reception if it were written today.  Enjoyable on its own terms.
**   A solid book, worth reading if you like the author's works.
*    Nothing special.
 
Additional disclaimers:  Authors are not chosen for review in any particular
order.  The reviews don't attempt to be comprehensive.  No distinction is 
made between books which are still in print and books which are not.
