Chapter of the First Book; That which appertains to Religion, of which he treats in the Third and Fourth Books, and that which relates to publick Conveniencies, as Town-Houses, Theatres, Baths, Academies, Market-places, Gates; of which he treats in the Fifth Book.
The Gnomonical part is treated of in the Ninth Book.
The Third Part which treats of Machines, is treated of in the Tenth and Last Book.
Besides these particular Matters of Architecture, there are Three things that appertain to all sort of Edifices, which are, Solidity, Convenience, and Beauty. He speaks of Solidity in the Eleventh Chapter of the Sixth Book; of Convenience, in the Seventh Chapter of the same Book; and of Beauty through the whole Chapter of the Seventh Book; which contains all the Ornaments that Painting and Sculpture are capable of giving to all sorts of Fabricks; and as to Proportion, which ought to be esteemed one of the principal Foundations of Beauty, it’s treated of throughout all his Works.
But to make it better understood, in what Method every Book explains those things, we must tell you, That in the First Book, after having treated of those things that belong to Architecture in General, by the Enumeration of the Parts that compose it, and of those that are required in an Architect, the Author explains in particular what choice ought to be made of the Seat where we ought to Build, as to Health and Convenience; after he speaks of the Foundations and of the Building of Fortifications, and the Form of Towers and Walls of Cities, he dilates himself upon the Air and Healthiness of the Situation.
In the Second Book, he speaks of the Original of Architecture, and what were the first Habitations of Mankind; after he treats of the Materials, viz. of Brick, Sand, Lime, Stones, and Timber: After which he treats of the different Methods of laying, binding, and Masonry of Stones. He Philosophizes upon their Principles, and upon the Nature of Lime, upon the choice of Sand, and the time of cutting of Wood.
The Third Book treats of the Proportion of the Temples, and of seven sorts of them which are those called Antes, Prostyle, Amphiprostyle, Periptere, Pseudiptere, Diptere and Hypæthre. After he speaks of the Different spaces that ought to be betwxit every Pillar, to which he gives the Five Names following, (which in the latter Part of this Book shall be more fully explained, as well as divers Terms of Art) viz. Pycnostyle, Systyle, Diastyle, Aræostyle and Eustyle. After that, he gives in particular the Proportions of the Ionick Order, and demonstrates that it has a Proportion with Humane Bodies.
The Fourth gives the Proportion of the Corinthian and Dorick Orders for Temples, with the Proportions of all the Parts that compose them.
The Fifth treats of Publick Fabricks, viz. of Market-places, Theatres, Palaces, Baths, Schools for Sciences, and Academies for Exercises, and in Conclusion, of Sea-Ports; and after occasionally discourses at large upon Musick, because, speaking of Theatres, he gives an account how the Ancient Architects, were in some places of the Theatre wont to place Vessels of Brass to serve for several sorts of tunable Echo’s, and augmenting the Voice of the Comedians.
In the Sixth he teaches what were the Proportions and Forms of private Houses among the Greeks and Romans, as well in the City as Country; and describes all the parts of the House, viz. the Courts, Porches, Halls, Dining Rooms, Chambers, Cabinets and Libraries.
In the Seventh he treats of the manner of making use of Mortar for Plaster and Floors; how Lime and the Powder of Marble ought to be prepared to make Stuck. He speaks likewise of the Ornaments that are common to all sorts of Buildings, as Painting; and all sorts of Colours, as well Natural as Artificial, that the Ancients made use of.
In the Eighth he speaks of Waters, and Rivers, and Fountains; viz. of their Springs, of their Nature, and Properties; how they are to be sought; and of the Conduits that are to bring them to Cities and Villages.
The Ninth is wholly Gnomonical, and teaches the manner of making Sun-Dials, and gives an account of the Rules of Geometry, how to measure solid Bodies. He discourses at large of the Course of the Stars, and the particular Description of those that are called Fixed Stars.
The Last is taken up wholly in the Description of making Machines to lift up great Weights, and others for several uses; viz. for the Elevation of Water for Corn-Mills, Water-Organs and Measuring the Way as well by Sea as by Land; but it chiefly treats of Machines fit for the use of Building and War.
PART I
Of Architecture that is common to us with the Ancients
CHAP. 1
Of Architecture in General
Lib. 2.
Chap. 1. IT’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 to Lib. 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 of Pillars, Architraves, Frises, Triglyphs, Mutils, Brackets, Corniches, Frontons or Piediments, 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. The Architraves which are laid across many Pillars, represent Summers that join many Posts together. The Frises imitate the Muring that is raised upon the Summers betwixt the ends of the Beams that are laid directly upon the Pillars. The Triglyphs represent the Ceiling or Joyner’s work which was made upon the ends of the Beams to conserve them. The Corniches are as it were the extream parts of the Joists. The Modillions represent the ends of the Sheers, and the Dentels represent the ends of the principal Rafter. The Frontons are made in imitation of the Firms or Girders, 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 common Lib. 4.
Chap. 2. Opinion, that the first Fabrick that was made, according to any of the Orders, was the Temple that King Dorus built in Honour of Juno in the City Argos. And it obtained the name of the Dorick Order, when Ion the Conducter of a Colony, which he established in Asia, made many Temples be built according to the Model of the Temple built by Dorus in Greece.
But the Ionians having changed some of the Proportions and Ornaments of the Dorick Order, were the Authors of another Order, which was called the Ionick, according to which, they built a Temple in Honour of Diana. 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
