Aims and Scope of the Series
This book series aims to establish a well defined forum for Monographs and
ProceedingsontheHistoryofMechanismandMachineScience(MMS).Theseries
publishes works that give an overview of the historical developments, from the
earliest times up to and including the recent past, of MMS in all its technical
aspects.
Thistechnicalapproachisanessentialcharacteristicoftheseries.Bydiscussing
technicaldetailsandformulationsandevenreformulatingthoseintermsofmodern
formalisms the possibility is created not only to track the historical technical
developments but also to use past experiences in technical teaching and research
today. In order to do so, the emphasis must be on technical aspects rather than a
purely historical focus, although the latter has its place too.
Furthermore,theserieswillconsidertherepublicationofout-of-printolderworks

Descriptive Geometry and Mechanism
Science from Antiquity to the 17th
Century: An Introduction

Abstract The focus of this brief introduction is the common birth and parallel
destiny of Descriptive Geometry and Mechanism Science. This argument will

Introduction
DescriptiveGeometryandAppliedMechanics,andmoreparticularlytheTheoryof
Mechanisms, which are at first sight disciplines belonging to separate and disjoint
fields, actually hide a common birth and parallel destiny.
Since ancient times, with Vitruvius and then in the Renaissance with
Brunelleschithetwodisciplinesbegantoshareacommondirectionwhich,overthe
centuries,tookshapethroughlesswell-knownfiguresuntilthemorerecenttimesin
which Gaspard Monge worked.
Understood in its modern sense, the Theory of Machines and Mechanisms can
betracedbacktothefoundingoftheÉcolePolytechniqueinParisandparticularly
to Monge and Hachette, personalities who made a fundamental contribution to the
development of Descriptive Geometry.
Over the years, a gap has been created between the two disciplines, which now
appear to belong to different worlds. In reality, however, there is a very close
relationshipbetweenDescriptiveGeometryandAppliedMechanics,alinkbasedon

extremely solid foundations; just think that without the theoretical foundations of
geometry it would not be possible to draw and design mechanical parts such as
gears,whileinkinematicsitwouldbelesseasytodesignandpredictthereciprocal
movements of the parts in a complex mechanical assembly (Fig. 1).
Thereafter, a long list of scholars can be identified who spanned the two dis-
ciplines, studying and researching in Descriptive Geometry and Mechanics in
alternatingphasesoftheirscientificpaths,andwhowereauthorsofbooksinoneor
another subject matter.
In this book we will try to better delineate this matter, considering some sci-
entistsfromthechosenperiodwhocanbeconsideredofcommoninterest between
the two disciplines, devoting a chapter to each of them. And especially in this
introductory chapter we will discuss four major personalities, one for Antiquity
(Vitruvius),onefortheMiddleAges(VillarddeHonnecourt),onetheRenaissance
(Filippo Brunelleschi), and finally one for the Baroque period (Giovanni Branca).
In our discussion we will try not to lose sight of the development of the two
disciplines, devoting to each personality a brief summary that puts their contribu-
tiontothestateoftheart ofthetimeintoproper context.Continuing ourresearch,
we will make use of the representations that our authors include in their works,

analysing alternately drawings of machines and architectural drawings, or func-
tional representations in geometric theories.
Theanalysesofthesegraphicalrepresentations(whichareoftendesignprojects)
will also lead us to talking about drawings, analysing wherein at times the two
disciplinesintertwineandsometimesconfronteachother,becausetheywerealways
deeply rooted in the culture of their epochs.
Infact,theory,basedonpureknowledgeandtechnology,basedonexperiments,
for centuries remained two opposite worlds. Since ancient times, in the wake of
Aristotelian philosophy, theory was the domain of those who in the Middle Ages
were called practitioners of the “liberal arts”, while technology belonged to the
“mechanical arts”.
In later times, enlargement of the terrestrial and celestial worlds, happening

profound ideological change that accompanies the early developments of technol-
ogy; a new philosophical interpretation of the mechanical arts makes its début—a
way of knowing linked to active exploration of the nature that exceeds the
Aristotelian concept of contemplative science.
Technologicaldevelopmenthasineveryagegreatlyinfluenced evolutionofthe
representation of design sketches, whether it was related to the representation of
architecture or if it was an expression of a project related to mechanics. In par-
ticular, the drawings of mechanical elements such as mechanisms, from an initial,
highly descriptive, representation, has evolved towards an ever greater clarity of
representation that would facilitate a rapid and unequivocal interpretation.
In fact, from the Middle Ages to the Renaissance, technical drawing in general
and especially that of machines and mechanisms, is not an autonomous encoded
language but a figurative representation of an object that only rarely turns into a
schematic simplification, with the use of some simple convention that is tradi-
tionally applied but not formally declared; in addition, there was still a deeply
rootedbeliefthatornamentationenhancesthevalueofthematerial,andthebeauty
of its use.
Technical drawing in today’s sense comes only with the Industrial Revolution,
when production is broken down into various structural levels and the use of the
executive project rather than summary schematisation is introduced to clarify the
features and perform the design calculations.
On the other hand, in terms of Descriptive Geometry, the situation is certainly
more complex.
On the one hand, it can be considered as a discipline that collects in an organic
whole the rules devised by painters and designers to delineate on a flat surface

is obvious that its origins date back to the origin of man. This understanding of
geometry will lead to the development of perspective in painting, with the funda-
mentalcontributionofBrunelleschiand,forarchitecture,refinementoftherulesfor
the representation of construction projects, whose development is still ongoing
today.
