If, as Besson
declares, he began to assemble his mechanical inventions in 1544, it
is difficult to assume, as biographers vie with each other to do, that
he was born in 1540. It would be preferable to consider the early 1530s,
or even the end of the 1520s. Let us not forget that he was a native
of Colombière, in the Oulx valley, at that time the Escarton
d’Oulx. So Besson was born in the Vaux area. We know nothing about
the origin of his reformed faith. He died in 1573, perhaps in Montargis
where he lived near Renée de France, the duchess of Ferrare who
welcomed numerous Huguenot refugees. Among them was Androuet du Cerceau,
her architect, the originator of the engravings in the Livre
and the Théâtre des instruments.
Even if
several shady areas remain, we now know much more about the history
of the conception of this work, its preparation, its financing, of its
various phases starting from the initial manuscript, the manufacturing
of it, and its successive publications and editions. It is no doubt
the major work of this inventor of machines, engineer and distiller
who introduces himself in his works as a teacher of mathematics. What
was it that caused Jacques Besson to initiate for posterity the literary
genre, the "théâtre de machines"?
We know
very little about his training. He was probably fluent in Latin, because
he published his first work in that language. He might have begun his
education at the Abbaye d’Oulx which had a grammar school. After
his first years of study, he tells us that he left for Italy and one
can surmise that it was there that he began to assemble drawings of
machines and instruments. These collections were put together by all
mathematicians/inventors of machines or engineers. The historical studies
of these last decades have fully confirmed this. The main part of Besson’s
professional activity was "mathematical", which included mixed
mathematics and mechanics. His mathematics courses certainly included
courses on theory- in particular, those he taught in Paris in Latin
in the early 1550s and some courses in pratical and mixed mathematics
in Geneva from 1559 to 1562 and in Orléans from 1565 to 1569.
As an engineer and mechanical engineer, an inventor of instruments and
machines, quite possibly Besson was active as early as his youthful
trip to Italy, but his first known works are situated in Switzerland:
from 1557 to 1559 in service with the city of Lausanne, then with the
lords of Berne, and from 1559 to 1562 with the city of Geneva. At the
same time as he taught lessons of mathematics he accomplished various
public works which fell within the province of his mechanical competence.
These activities brought him a modest but regular salary. If it is plausible
to think that he put his engineering talents to work when he was with
Olivier de Serres, from 1562 to 1564, we have no trace of it. We know
that he was in Orléans from 1564 to 1569, teaching practical
mathematics, because of the publication of his Cosmolabe (Paris,
1567). The invention of this instrument gave rise to an impropriety
on the part of two of Besson’s disciples, "Remon Poynet"
and "Benoît l’Enginneur", a manufacturer of mathematical
instruments, for, in 1566 Poynet published in Paris, at the bookseller
Michel Julien’s shop, Le Cosmolabe, à la roynes mère
du roy. Its dedication is dated June 1566. As early as September
1566, Besson denounced the theft, "ils ont usurpé le droit
de leur maistre", emphasizing that "chacun cognoist assez
par l’effect de mes autres inventions, si j’ay esté
capable de trouver le Cosmolabe". In turn he dedicated
his treatise to Catherine de Médicis and his editor Philippe
de Roville obtained a royal privilege. The inventions listed by Besson
in the foreward of the Cosmolabe deal with several geometrical problems
with practical applications, with chorography, perspective, geography
and astronomy. He proposes machines and instruments, a certain number
of which would make up the Théâtre des instruments
mathématiques.
We see further
mention of the future theatre of machines as dedications and printer’s
notes appear during these years. In August 1568 Besson dedicated his
Art et moyen parfaict de tirer huyles et eaux to François
de Balzac d’Entraigues and asserts that "par vostre moyen
j’ay poursuivi et continué l’exercice de mes estudes
Mathematiques". September 6, 1569, in his dedication to the Art
et science de trouver les eaux et fontaines cachées sous terre,
he wrote "je travaille aussi à present, pour dedier à
Sa Majesté, à un ample livre, distribué en plusieurs
inventions nouvelles d’instruments & machines utiles".
December 8, 1570, Galiot du Pré, printer of the Art et
moyen parfaict de tirer huyles & eaux writes about Besson that
he "a impetré & obtenu cette faveur & commandement
du roi notre sire, de luy bastir & dresser un autre sien œuvre,
declaratif de diverses machines inventions mathematiques, for recommendables
& necessaires à nostre Republique". Besson thus obtained
royal support and in his preface to the 1571 edition of the Art
et moyen parfaict de tirer huyles et eaux..., he explains that
he owes François de Montmorency for having introduced him to
the king and for having made him understand "qu’il est impossible
que je puisse proffiter au public, et subvenir aux frais qu’il
me conviendra faire, pour mettre en evidence mes œuvres et inventions
de mathematiques, sans estre liberalement aydé et entretenu de
sa Majesté".
In December
1570 Besson, who had left Orléans a year earlier, was living
in Montargis. When he went to Paris he resided with Philippe Lo, an
apothecary, in the faubourg Saint-Jacques. A protégé of
the duchess of Ferrare, Besson was therefore close to Androuet du Cerceau
whom he asked to engrave the plates of the Livre d’Instruments.
And as explained by Galiot du Pré, busy with preparing the engravings,
one can assume that his manuscript was finished. This manuscript, discovered
at the British Library, was presented by Alex Keller (1976) saying "in
short, we have here not only an early state of Besson’s book,
but also the unique short treatise which summarises the theories of
mecanics which he believed his inventions exemplified" (p. 76).
In fact, after the dedication to the king, the manuscript includes a
whole first theoretical part, made up of twenty-two principles and two
"communes sentences", a part that was not taken up again in
the successive editions of the work. It shows an Aristotelian approach,
in which intervene particular analytical elements taken from the Problèmes
mécaniques of the Pseudo Aristotle. As in his Art et
Science de trouver eaux et fontaines, Besson asserts the autonomy
of mathematical reasoning and its power to explain the effects obtained,
even if its hypotheses are not physically established. This approach
has a lot in common with the tradition belonging to the inventors of
machines of antiquity who are searching for methods of calculating and
do not claim to attain the physical truth of the phenomena, but only
to calculate the effects of external causes (i.e., artificial ones).
In this respect, Besson’s frequent reference to Copernicus aims
at making very clear the advantage obtained by a hypothesis confining
its ambition to saving appearances, that is, giving a mathematical account
of phenomena, by taking support from an undeniably false representation
of the world (heliocentrism). The manuscript was carefully studied by
Alex Keller (1976), and Denise Hillard (1981) compared it word by word
with the first edition (Latin/French) dated probably 1571, at the latest,
the beginning of 1572. In fact, "à Jaques Besson, ingenieur
et mathematicien a été allouée la somme de 560
l. t. en consideracion de ses services et pour le recompenser d’ung
livre des angins et instrumens mathematiques qu’il a presenté
et dedié a sadite majesté…" was found in the
Comptes royaux, dated May 12, 1572. It came out in Paris, printed by
Fleury Prévost, if the card catalogue at the Part-Dieu Library
in Lyons can be believed.
The few
rare copies of the first edition which have come down to us note neither
place of publication nor date. The privilege, on the back of the title
page, indicates: "donné à Orleans, l’an mil
cinq cens soixante-neuf, le vingt-septiéme iour de Iuin".
Let us not forget that in December 1570 the printer Galiot du Pré
announced that Besson was marshaling and preparing "les figures
necessaires audict œuvre". The recovered manuscript is the
one which Androuet du Cerceau used as a model to engrave his copper
plates, for a great majority of the drawings which were reproduced in
the plates were inverted. Four of the sixty plates of the Livre
premier were engraved by René Boyvin. The "first"
book of the Instruments et machines... did not have the sequel
that Besson had planned, and his projects were interrupted by his death
during the year 1573.
