Of Architecture in General.ARTICLE I.Of the Original of Architecture.
Lib. 2.Chap. 1.
T’s related by Historians, That Men, who in former times inhabited
Woods and Caverns like wild Beasts, first assembled themselves to
make Houses and Cities, which was occasioned by a Forest that was
set on fire, which drew all the Inhabitants together by its novelty
and surprizing effects; so that many Men meeting together in the
same place, they found out means, by helping one another, to
harbour themselves more conveniently, than in Caves and under
Trees; so that it is pretended, that Architecture was the Beginning
and Original of all other Arts. For Men seeing that they had
success in Building, which necessity made them invent, they had the
Thoughts and Courage of seeking out other Arts, and applying
themselves to them.
Now even as they took Trees, Rocks and other Things
that Nature her self furnished Beasts to harbour themselves under,
which were made use of as Models for the first Houses, which at
first were only made of green Turf and broken Branches of Trees,
they made use of them afterwards, in the same manner, to arrive at
something more perfect. For passing from the Imitation of the
Natural toLib. 4.Chap. 2.that of Artificial, they
invented all the Ornaments of Edifices that were most curiously
wrought, in giving them the Form and Shape of those things that are
simply necessary to the most natural Buildings: And the Pieces of
Timber of which the Roofs and Floors of Houses are made, were the
Original ofPillars,Architraves,Frises,Triglyphs,Mutils,Brackets,Corniches,FrontonsorPiediments, which are made of Stone or
Marble.The Pillars which are to be smaller at top than at bottom,
were made in Imitation of the Boles or Trunks of Trees, and their
use was taken from the Carpenters' Posts that are made to support
the Building. TheArchitraveswhich are laid across manyPillars, representSummersthat join manyPoststogether. TheFrisesimitate theMuringthat is raised upon theSummersbetwixt the ends of the Beams
that are laid directly upon thePillars. TheTriglyphsrepresent the Ceiling or
Joyner’s work which was made upon the ends of the Beams to conserve
them. TheCornichesare as it
were the extream parts of theJoists. TheModillionsrepresent
the ends of the Sheers, and theDentelsrepresent the ends of the
principalRafter. TheFrontonsare made in imitation of
theFirmsorGirders, upon which is laid the Roof
of the House.There is likewise another Original of Architecture, which is
taken from the Inventers of the several Orders, and those that
added the Ornaments to embellish them. For it’s the commonLib. 4.Chap. 2.Opinion, that the first
Fabrick that was made, according to any of the Orders, was the
Temple that KingDorusbuilt in
Honour ofJunoin the
CityArgos. And it obtained the
name of theDorickOrder,
whenIonthe Conducter of a
Colony, which he established inAsia, made many Temples be built according to the Model of the
Temple built byDorusinGreece.But theIonianshaving
changed some of the Proportions and Ornaments of theDorickOrder, were the Authors of
another Order, which was called theIonick, according to which, they built
a Temple in Honour ofDiana.
The reason of this change was, that this Temple being dedicated to
a Divinity, which they represented under the Shape of a Young Lady,
they thought it was proper to make their Pillars more tapering, the
better to represent the airy Stature of this Goddess, and for this
reason they adorned it more delicately, adding Bases which
represent the Buskin'd Ornaments of the Legs and Feet, according to
the Mode of that time; and Made theChannellingsdeeper to represent the
Foldings and Plaits of a fine light Garment. They put
likewiseVolutesorScrowlsupon theCapital, pretending that they imitated
the Head-Dress of a Young Lady, whose Hair Beautifully descending
from the top of her Head, was folded up under each
Ear.AfterwardsCalimachusanAthenian, embellished
the Capitals of the Pillars, adding to them more BeautifulVolutesorScrowls, and more in number, enriching
them with the Leaves ofBrank Ursineand Roses. It’s said, That this Capital, which, according
toVitruvius, makes all the
Distinction betwixt theCorinthianandIonickOrder, was
invented by this ingenious Artisan upon this occasion. Having seen
the Leaves of the above-mentioned Plant grow round about a Basket
which was set upon the Tomb of a YoungCorinthianLady, and which, as it
happened, was set upon the middle of the Plant. He represented the
Basket by theTambourorVaseof the Capital, to which he made
anAbacusto imitate the Tile
with which the Basket was covered, and that he represented the
Stalks of the Herb by theVolutesorScrowls, which were
ever after placed upon theCorinthianCapital. See Table theIXth.This great Artist likewise invented other Ornaments, as those
we callEggs, because of
theOvalsin theReliefwhich are in the Mouldings of
theCornichesand are
likeEggs. The Ancients called
this OrnamentEchinus, which
signifies the sharp prickly shell of Chestnuts, because they found
these Ovals represented a Chestnut half open, as it is when it’s
ripe.Lib. 3.Chap. 2.He likewise makes mention of
another Famous Author, who found out the proportion of all the
Parts of a Fabrick, which wasHermogenes; to whom he attributes the
Invention of theEustyle,Pseudodiptere, and of
all that is beautiful and excellent in Architecture.ART. II.What Architecture is.
Rchitecture is a Science which ought to be accompanied with
the Knowledge of a great many other Arts and Sciences, by which
meansLib. 1.Chap. 1.it forms a correct Judgment of
all the Works of other Arts that appertain to it. This Science is
acquired byTheoryandPractice. TheTheoryofArchitectureis that Knowledge of this
Art which is acquired by study, travelling and discourse. The
Practick is that knowledge that is acquired by the Actual Building
of great Fabricks. These Two Parts are so necessary, that never any
came to any great Perfection without them both. The one being lame
and imperfect without the other, so they must walk hand in
hand.
Besides, the Knowledge of things that particularly
belong to Architecture, there are infinite other things that are
necessary to be known by an Architect.For, First, it’s necessary that he be able to couch in
writing his intended Building, and to design the Plan, and make an
excellent Model of it.Geometry likewise is very necessary for him in many
occasions.He must also know Arithmetick to make a true
Calculation.He must be knowing in History, and be able to give a reason
for the greatest part of the Ornaments of Architecture which are
founded upon History. For Example, if instead of Pillars he support
the Floors of the House with the figures of Women, which are
calledCariatides, he ought to
know that theGreeksinvented
these Figures to let Posterity know the Victories they obtained
over theCariens, whose Wives
they made Captives, and put their Images in their
Buildings.It’s necessary likewise, that he be instructed in the
Precepts of Moral Philosophy; for he ought to have a great Soul,
and be bold without Arrogance, just, faithful, and totally exempt
from Avarice.The Architect also ought to haveLib.
1.Chap. 11.a great Docility which may
hinder him from neglecting the advice that is given him, not only
by the meanest Artist, but also by those that understand nothing of
Architecture; for not only Architects, but all the World must judge
of his Works.Lib. 1.Chap. 2.Natural Philosophy is likewise
necessary for him for to discover what are the Causes of many
things which he must put a remedy to.He ought also to know something ofPhysick, to know the qualities of the
Air, which makes Places Healthful and Habitable, or the quite
contrary.He should not be ignorant of the Laws and the Customs of
Places for the Building of Partition Walls, for prospect and for
the conveying of Waters and Sewers.He ought to knowAstronomy, that he may be able to make all sorts of
Dials.It was necessary among the Ancients, that an Architect should
have skill inMusickto make and
orderCatapultsand other
Machines of War, which were strung with strings made of Guts, whose
sound they were to observe, that they might judge of the strength
and stiffness of the Beams which were bended with those
Strings.Musickwas also
necessary in those days for the placing musically Vessels of Brass
in the Theatres, as we have said before.ART. III.What are the Parts of Architecture.
Here are Three Things which ought to meet in every
Fabrick,viz. Solidity,ConvenienceandBeauty, which Architecture gives them;
by the due ordering and disposition of all the Parts that compose
the Edifice, and which she rules by a just Proportion, having
regard to a trueDecorum, and
well regulatedOeconomy; from
whence it follows, that Architecture has Eight Parts,viz. Solidity,Convenience,Beauty,Order,Disposition,Decorum,Oeconomy.
Soliditydepends upon the
goodness of the Foundation, choice of Materials, and the right use
of them; which ought to be with a due order, disposition and
convenient Proportion of all Parts together, and of one in respect
of another.Conveniencelikewise consists in the
ordering and disposition, which is so good that nothing hinders the
use of any part of the Edifice.Beautyconsists in the excellent and
agreeable form, and the just proportion of all its
parts.Orderis that which makes, that all the
parts of an Edifice have a convenient bigness, whether we consider
them apart or with Relation to the whole.Dispositionis the orderly Ranging and
agreeable Union of all the parts that compose the Work; so that as
Order respects the Greatness, Disposition respects Form and
Situation, which are Two Things compriz'd under the wordQuality, whichVitruviusattributes to Disposition,
and opposes to Quantity, which appertains to Order. There are three
ways by which the Architect may take a view beforehand of the
Fabrick he is to build,viz.First,Ichnography, which
is theGeometricalPlan;Orthography, which is theGeometrical Elevation, andScenography, which isPerspective Elevation.Proportion, which is also
call'dEurythmy, is that which
makes the Union of all parts of the Work, and which renders the
Prospect agreeable, when the Height answers the Breadth, and the
Breadth the Length; every one having its just measure. It is
defin'd, the Relation that all the Work has with its Parts, and
which every one of them has separately to the Idea of the whole,
according to the measure of any Part. For as in Humane Bodies there
is a Relation between the Foot, Hand, Finger and other Parts; so
amongst Works that are Perfect, from any particular Part, we may
make a certain Judgment of the Greatness of the whole Work: For
Example, the Diameter of a Pillar, or the Length of aTriglyph, creates in us a right
Judgment of the Greatness of the whole Temple.And here we must remark, that to express the Relation that
many things have one to another, as to their Greatness or different
Number of Parts,Vitruviusindifferently makes use of three words, which areProportion,EurythmyandSymmetry. But we have thought it
proper only to make use of the word Proportion, becauseEurythmyis a Greek word, which
signifies nothing else but Proportion; and Symmetry, although a
word commonly used, does not signifie in the Vulgar Languages
whatVitruviusunderstands by
Proportion; for he understands by Proportion, a Relation according
to Reason; and Symmetry, in the vulgar Languages, signifies only, a
Relation of Parity and Equality. For the wordSimmetriasignifies in Latin and
GreekRelationonly. As for
Example, as the Relation that Windows of Eight Foot high, have with
other Windows of Six Foot, when the one are Four Foot broad, and
the other Three: and Symmetry, in the Vulgar Languages, signifies
the Relation, for Example, That Windows have one to another, when
they are all of an equal height and equal breadth; and that their
Number and Distances are equal to the Right and the Left; so that
if the distances be unequal of one side, the like inequality is to
be found in the other.Decorum or Decency, is that which makes the Aspect of the
Fabrick so correct, that there is nothing that is not approv'd of,
and founded upon some Authority. It teaches us to have regard to
three things, which are,Design,CustomandNature.The Regard to Design makes us chuse for Example, other
Dispositions and Propertions for a Palace than for a
Church.The Respect we have to Custom, is the Reason, for Example,
That the Porches and Entries of Houses are adorned, when the Inner
Parts are Rich and Magnificent.The Regard we have to the Nature of Places, makes us chuse
different Prospects for different Parts of the Fabrick, to make
them the wholsomer and the more convenient: For Example, the
Bed-Chambers and the Libraries are exposed to the Morning Sun; the
Winter Apartments, to the West; the Closets or Pictures and other
Curiosities, which should always have equal Light, to the
North.Oeconomy teaches the Architect to have regard to the Expences
that are to be made, and to the Quality of the Materials, near the
Places where he Builds, and to take his Measures rightly for the
Order and Disposition;viz.to
give the Fabrick a convenient Form and Magnitude.These Eight Parts, as we have said, have a Relation to the
Three first,viz. Solidity,Convenience,Beauty, which suppose,Order, Disposition,Proportion,DecorumandOeconomy. This is the reason that we
divide this first Part only into Three Chapters; the first is of
the Solidity; the second of the Convenience; the third of the
Beauty of the Fabrick.
Of the Solidity of Buildings.ARTICLE I.Of the Choice of Materials.
HE Materials of whichVitruviusspeaks are, Stone, Brick, Wood, Lime, and Sand.
All the Stones are not of one sort, for some are soft,
some harder, and some extreamly hard.Those that are not hard are easily cut, and are good for the
Inner Parts of the Buildings, where they are cover'd from Rain and
Frost which brings them to Powder, and if they be made use of in
Buildings near the Sea, the Salt Particles of the Air and Heat
destroys them.Those that are indifferently hard, are fit to bear Weight;
but there are some sorts of them, that easily crack with the heat
of the Fire.There is likewise another sort of Stone, which is a kind of
Free-Stone; some are Red, some Black, and some White, which are as
easily cut with a Saw as Wood.The best Bricks are those which are only dry'd and not baked
in the Fire; but there are many Years required to dry them well:
and for this Reason, atUtica,
a City ofAfrica, they made a
Law, That none should make use of Bricks which had not been made
five Years: For these sort of Bricks, so dry'd, had their Pores so
close in their Superficies, that they would swim upon Water like a
Pumice-Stone; and they had a particular Lightness, which made them
very fit for all sorts of Buildings.The Earth of which these Bricks were usually made was very
Fat, and a sort of White Chalky Clay without Gravel or Sand, which
made them Lighter and more Durable; they mixed Straw with them to
make them better bound and firmer.The Woods which were made use of in all Buildings, are Oak,
Poplar, Beech, Elm, Cypress, Firr; but some of them are not so
proper for Building as others.
