l Publick Buildings, ought to be large and
streight, and to have many Entrances, to the End the People may come in
and out conveniently; but we shall speak of this more largely in another
place.

The Halls where great Assemblies are to meet, ought to have their
_Ceiling_ very high, and to give them their true Proportion, we must
unite the Length and Breadth, and give the half of the whole for the
height of the _Ceiling_. The Halls where the _Ceiling_ is not so high,
must have only their breadth, and half of their length for their height.

[Sidenote: _Lib. 5. Chap. 2._]

In vast and high places, to remedy the Inconvenience of the noisy Echo,
about the middle of the height of the Wall, must be made a _Cornish_
round about to break the course of the Voice; which without that,
beating against the Walls, would beat a Second time against the
_Ceiling_, and cause a troublesom double Echo.

_Of the Beauty of Buildings._

ARTICLE I.

_In what the Beauty of Building Consists._

_Buildings_ may have two sorts of Beauty, the one _Positive_, and the
other _Arbitrary_. _Positive Beauty_, is that which necessarily pleaseth

accompany her.

As to what regards the Relation of the Parts of the Fabrick one to
another, _Vitruvius_ hath not spoke of it, but only where he prefers the
_Netway_ of Walling before all other sorts of _Masonry_, because of the
Uniformity that is in that Figure, and the laying of the Stones; As to
the Richness of the Materials, he leaves the Disposition to him that is
at the Expences of the Building; and he acknowledges that the Beauty of
the Performance depends wholly upon the Dexterousness and Industry of
the Workmen.

The second sort of _Beauty_, which only pleases by the Circumstances
that accompany it, is of two sorts; The one is called _Wisdom_, and the
other _Regularity_. _Wisdom_ consists in the reasonable use of _Posi
