The chemist is a horrible, morally corrupt
person,
and there does not seem to be any single term awful enough to describe
him. At least that was Libavius’ opinion of those involved in chemical
experimentation. This scholar even asked, "What is more abject than a
chemist?"
This short quotation from the reviewed book
should
illustrate its approach. We find here an attempt to address significant
points concerning alchemy and chymistry in the turbulent development of
ideas during a historical epoch known as the Scientific Revolution. It
should be emphasized that Moran successfully draws, in the format of a
small book, the multifaceted picture of an epoch in which not only
science, but also European society as a whole, endured deep changes
under conditions that were often stormy. The Thirty Years War was one
such dramatic peak. Concerning Libavius’ opinion of chemists cited
above, we will leave it to the reader to find the explanation of this
seemingly strange attitude. In the book we meet this German scholar
repeatedly.
Although the reviewed book does not consider
itself
to be classified among the ‘top scholarly works’, Moran’s introductory
sentences already indicate that his book is not simply easy reading for
a Sunday afternoon either. Basic knowledge of history in general, and
of alchemy and chymistry in particular, is necessary for understanding
it. The author begins with discussing whether or not alchemy can be
regarded as ‘scientific’ with reference to the revolution in science
that occurred during the sixteenth and seventeenth centuries. In other
words: Was alchemy a science? Past opinions varied broadly, and this
has remained so until recent times. Two extremes can be recalled here.
On one side there appeared a very strict condemnation of alchemy by
Nicholas Lemery, one of the personalities that also appear in the
reviewed book. Contrary to Lemery, about two centuries later, the
chemist Justus von Liebig (1803-73) did not find anything wrong with
alchemy and did not perceive a difference between this science and his
contemporary chemistry. Moran’s book follows the vicissitudes of
alchemy, which had never been included into university curricula,
though it had permeated European society not only in the discussed
epoch.
The publication of Moran’s book coincides
happily with William R. Newman’s Promethean Ambitions
(see the following review). Although the latter book covers a much
broader historical period and concentrates on different topics, it
should be strongly recommended to study both works, as they are in some
respects complementary. Taken together they can yield deeper insight
into the world of alchemy and early chemistry. But back to Moran’s book.
It is divided into six numbered chapters
followed by a Conclusion,
a list of references, and an index. In this review we will briefly
discuss these chapters, in some cases with remarks that are not
intended as criticisms; the book is written in a compact form, and it
would surely be difficult, if not impossible, to include more
information into such a focused volume. Some of the following comments
are rather suggestions for future editions (the reviewer hopes that
they will appear). On the other hand, it is just its compactness that
makes this book excellent reading for those who want a basic
description of European alchemy during a period of important change.
The list of references is a guide for the further study of this topic.
In the Introduction the author asks
"what
would happen if we could find a way to drop into the sixteenth and
seventeenth centuries and see the world from the historical inside
out?" It is not easy to imagine, because the result would depend on our
social status, if we were a nobleman, a beggar, a scholar, or a soldier
in the Thirty Years War. The last possibility is unlikely; the author
intends to look through the prism of a scholar. Perhaps a broader view
that could be observed from this position would yield a picture like
that described by Marie Boas-Hall in The Scientific Renaissance
1450 – 1630 (Dover, New York, 1994), which is not included into the
list of references.
In the second chapter, Doing Alchemy,
the
reader meets Libavius for the first time in this book. Moran states
that this famous German scholar does not belong "in the pantheon of
great chemists". We can agree with this point of view, because Libavius
seems to have sat uncomfortably between alchemy, with its belief in
transmutation, and the emergence of what gradually became modern
chemistry. The latter contradicted the former. Even among historians
the wish is sometimes father to the thought, and as a result Libavius
has been named as one of the founders of chemistry. This opinion is
true to some extent: his contribution to chemical knowledge is
indubitable, and his most cited work, Alchymia, was surely an
important source of information for its time, but it was not a textbook
of chemistry as we understand it. Sometimes it is forgotten that
Libavius wrote more than just that one book, and therefore Moran’s use
of some of Libavius’ other texts is of considerable interest.
Furthermore, there were other scholars who finally helped chemistry to
crystallize from a complicated mixture of alchemy, chymistry, and
craft. The contribution of artisans should not be overlooked; though
most of them will remain unknown, their practical skills introduced
various chemical processes, as is summarized in U. Klein’s Verbindung
und Affinität (Birkhäuser, Basel 1994), which would also
deserve to be included into the list of references.
Libavius is not the only name that appears in
this
chapter; for we also meet personalities who were active well before the
Scientific Revolution. The changes in meaning of the term fifth
essence
are illustrated by the works of John of Rupescissa, Raymund Lull
(alchemist), and Roger Bacon. Doing alchemy was surely not an easy job,
because it had been accompanied by the repeated failure to transmute
metals throughout the centuries. Yet there was continuous interest in
gold production, and King Henry VI is mentioned as a high-ranking
supporter of this aspect of alchemy. On the other hand, a papal bull
against alchemy issued by John XXII is also discussed. The part of the
latter text that refutes the possibility of metallic transmutation
deserves particular attention. The attitude of the church toward the
question of alchemy is discussed extensively in the above-mentioned
book by Newman.
In the second chapter, "That Pleasing
Novelty": Alchemy in Artisan and Daily Life,
the reader meets famous figures of metallurgy, like Biringuccio and
Georgius Agricola, as well as the much less-known alchemist Isabella
Cortese, an example of a woman active in this field. Among the
prominent representatives of mining and metallurgy Lazarus Ercker is
missing. He could serve as a striking example of how difficult the
question of metallic transmutation actually was. The threshold between
alchemy and chemistry was not easy to overcome, although the obstacle
in Ercker’s case was the chemical reaction in which copper is deposited
from a cupric solution onto the surface of metallic iron. This
reaction, known from antiquity, remained difficult to interpret even
into the eighteenth century. In the statement that appeared in his Beschreibung
Allerfürnemisten Mineralischen Ertzt
(1574), Ecker admitted that seeing iron nails and ladders in mines
changed into copper by vitriolous drainage water convinced him that
metallic transmutation is a possible process. We can follow Ercker’s
change of mind through time. Unfortunately the source we will cite here
is written in the Czech language, which makes it largely inaccessible
to the broader international public. In a manuscript dated 1569 Ecker
had written: "Many think that iron can become copper by the action of
vitriolic water. I will, of course, oppose that iron could have become
copper [...] it [iron] draws copper down and digests it." (L.
Kubátová, Neznámý rukopis Lazara
Erckera 1569
["An unknown manuscript of Lazarus Ercker 1569"], Státní
ústřední
archiv v Praze, 1996). Five years later, this skilled metallurgist gave
up and accepted the transmutation of iron into copper.
To the second part of the title of this
chapter, daily life,
we can perhaps add that it is not easy to describe the social status of
alchemists in the sixteenth and seventeenth centuries. This is
especially true for the German-speaking countries that formed the Holy
Roman Empire, which was a complicated world, split into some three
hundred states. There were numerous reasons for employing alchemists.
The most straightforward was of course the wish to gain access to a
source of gold, but in some cases it was also an effort to simply
demonstrate the status of a court. As P. Vágner has pointed out (Theatrum
chemicum
[in Czech], Paseka, Prague 1995), alchemists were sometimes considered
as part of the ‘living inventory’ of a court, together with
astrologers, musicians, painters, and various other artists. In Bohemia
there is even a typical example of belief in the medical effects of the
philosopher’s stone. The family of Rosenberg died out without a male
heir in 1611, and the last Rosenbergs wanted alchemists to produce
something that would change this fatal situation. Doing alchemy
had been a complicated process in the European Renaissance that still
calls for further study.
An interesting passage of the Moran’s book
deals
with ‘books of secrets’, a tradition reaching back to the Middle Ages.
These books combined knowledge from various fields for practical
purposes. The fourth manual that Moran discusses (p. 58) deals with
solutions for hardening steel tools, and recommends that files be
quenched in linseed oil or the blood of a male goat. This is
reminiscent of a medieval recipe that recommends the urine of a goat
fed on fern for similar purposes (Theophilus, On Divers Arts,
Dover, New York, 1978). The books of secrets are interesting in more
respects. They show that various fields, including alchemy,
communicated with each other to some extent. The goat products
appearing in such recipes, a reflection of natural magic, are
illustrations of belief in the supernatural that was deep in the human
mind for centuries.
Did Paracelsus really burn the books of the
most
respected medical authorities of his time (p. 73)? As some historians
have pointed out, he could have hardly collected enough means to
purchase such an expensive commodity. Yet this legend is not so
important, and does not dominate the third chapter, entitled Paracelsus
and the "Paracelsians".
Here the reader again meets the omnipresent Libavius and his division
of the types of people active in medicine and chymistry. Libavius thus
tried to draw a distinction between various ideas current in his time.
Also included in this chapter is the dramatic history of the French
Paracelsians. Considerable space is devoted to van Helmont, whose
medical philosophy and famous tree experiment are discussed.
Sites of Learning and the Language of
Chemistry
is the informative title of the fourth chapter, from which the
introductory sentence of this review was taken. Libavius’ definition of
chemistry is considered in this chapter, based on his division of what
belonged to chemistry and what not. Moran’s familiarity with the
history of alchemy at German courts allows him to describe the picture
of Marburg in the seventeenth century. This description is central to
the development of the chapter, though his discussion of how chemical
ideas developed and ripened in France from Beguin to Lemery is perhaps
more interesting, as anglophone books on the history of chemistry do
not always give enough attention to that country. Moran tells the story
of the origin of Beguin’s textbook, which was intended to open the
secrets of alchemy, something not thought about before. Beguin’s view
that chemistry is "the art of dissolving natural mixed bodies, and
coagulating the same when dissolved" was later expressed in similar
words by Glaser. Here Moran briefly describes the crucial point that
led eventually to chemistry; though there was still a long way to go.
Also of interest is the further development of ideas concerning acids
and bases.
The ‘English school’ with its prominent
representatives Boyle and Newton is discussed in the fifth chapter Alchemy,
Chemistry, and the Technology of Knowing.
Here, the reader should remember the previous chapter, because it is
especially interesting to compare the French and English chymists. Yet
alchemy in the British Isles is not the author’s only focus, as
suggested by the term ‘technology’ in the title of this chapter, which
begins with a discussion of the difference between experiment and
experience. As the author states, "something happened in the
seventeenth century". The experiments could be performed with a wider
variety of new apparatus, though only the air pump is mentioned. There
could surely be more examples collected, because this topic is of
considerable importance for the Scientific Revolution.
A newly discovered substance, phosphorus, had
attracted the attention of chymists and the broader public in the
seventeenth century. The discovery of this mysterious substance is
attributed to Johann Kunckel (p. 148) in the reviewed book. Kunckel,
however, had received instructions for its preparation from its true
discoverer, the Hamburg alchemist Henning Brand (M.E. Weeks, Discovery
of Elements,
1968). Another famous story has linked the German alchemist Johann
Böttger with the discovery of European porcelain, whereas the fate
of
his tutor, Walter von Tschirnhaus, is presented as being secondary in
this epochal event. As Prandtl had pointed out (W. Prandtl, ‘Zur
Vorgeschichte des Meissener Porzellans’, Chymia, 4 [1958],
115), the "Waldenburger Gefässe", vessels made from vitreous
ceramic
material, were already known in Agricola’s time. In his De natura
fossilium
Agricola even described how to achieve the vitrification of ceramic
material, though the product was not white. According to Prandtl, von
Tschirnhaus had proposed to the Saxonian Elector August II to build a
porcelain factory as early as 1702, but the latter was involved in a
war during that time, and thus had different problems to deal with.
Böttger was accepted in von Tschirnhaus’ laboratory in 1705, and
the
death of his master three years later opened the way for him to accept
the laurels of the discoverer.
The contribution of chemistry and mechanics
to medicine is one of the topics of the sixth and final chapter, The
Reality of Relationship.
Here Moran first discusses the position of various sciences in the
Scientific Revolution, and this question leads to the role of mechanics
in scientific thinking. As a striking example of this approach, the
explanation of the action of organisms by the German physician
Friedrich Hoffmann is given. This scientist applied the laws of
mechanics to this problem. Due space is of course devoted to Newton as
an alchemist, and to his role in the Scientific Revolution.
In the Conclusion the author points
out that
"chemistry itself did not so much replace alchemy as subsume it". In
his opinion, "in a disciplinary sense, chemistry is an extract, a
derivative of alchemy". In this chapter Libavius appears for the last
time, praised for his attempts to spread chemical knowledge. Finally,
when summing up what was said before, Moran emphasizes the role of
alchemy in the Scientific Revolution. Alchemy was one of numerous
voices in a chorus of growing sciences, a voice that has not always
been quite understandable, because alchemy vacillated between dream and
the sober reality of unsuccessful attempts to transmute metals and
spoke in its special language. In the epoch covered by the reviewed
book, the language of chymistry was not much more consistent.
As was said at the beginning of this review, Distilling
Knowledge
is a book that is not easy to classify into a certain group of
literature. In such a small volume not all facets of the complicated
structure of the Scientific Revolution can be touched upon. Therefore
the author selected only details that had far reaching effects.
However, this book is not simply introductory reading about European
alchemy and chymistry in the sixteenth and seventeenth centuries.
Instead, it is something in between: though not a source for the fully
uninitiated, it is built upon classic original texts and modern
secondary sources, and previous knowledge about the history of alchemy
and chymistry is expected. Moran’s book provides a very interesting
picture of the Scientific Revolution observed through the prism of the
alchemical laboratory. This book can be suitable to those who want to
be acquainted with an epoch that played a crucial role in the further
development of Europe. Therefore, it would be interesting for students
of the history of science, as well as of general history, but also as a
source for scholars to find points worthy of further consideration. We
can close by saying that this book is an attempt to distill the essence
of alchemical and chemical thinking in an epoch of turbulent changes in
Europe. The distillate that Moran has prepared fulfills the
expectations – it is very tasty and stimulating.
