They took likewise great Care to make the Approaches to the Walls difficult, ordering their Ways so, that they came not directly, but to the Left of the Gate. For by this means, the Besiegers were constrained to present to them that were upon the Walls the Right side, which was not covered with a Buckler. The Figure of a _strong_ place ought neither to be Square, nor composed of Angles that advance too far. But the Ancients made them with many Sinuosities or Corners, for Angles that are too far advanc'd, are more advantageous for the Besiegers, than the Besieged. The thickness of the Wall was so ordered, that two Armed Men might walk by one another upon the Wall without justling. They made their Walls strong and durable, with sindged Beams of Olive, which bound them and kept them up. Although there be nothing that makes the Ramparts so strong as Earth, they had not for all that the Custom of making Terrasses, unless it were in some place where some Eminency was so near the Wall, that the Besiegers might easily enter. To make the Terrasses strong, and to hinder the Earth from pushing down the two Walls that supported it, they made Buttresses or Counter-forts which went from one Wall to another, to the end, that the Earth being divided into many parts, might not have that weight to push the Walls. Their Towers were round, for those that are square are easily ruin'd by their War-like Engines, and their Battering easily broke down the Corners. Directly against the Tower, the Wall was cut off within the breadth of the Tower, and the Walls so interrupted were only joyned with Joyces, which were not nailed down; to the end, that if the Enemy made themselves Masters of some part of the Wall, the Besieged might take up this Bridge made of Joists, and hinder their further advance. ART. II. _Of Temples._ [Sidenote: _Lib._ 4. _Chap._ 4.] The second Sort of Publick Fabricks, which are those that belong to Religion are the _Temples_, which among the Ancients were of two Sorts; some were after the _Greek_, and some after the _Tuscan_ Fashion. The _Temples_ after the _Tuscan_ Fashion were Square, the _Greeks_ made them sometimes Round, sometimes Square; in the Square _Temples_ of the _Greeks_, there are three Things to be considered, _viz._ The Parts that compose it, the Proportion of the _Temple_, and its _Aspect_. The Parts of the Square _Temples_, were for the most part Five; for they had almost every one of them a Porch before the Temple called _Pronaos_, and another Porch behind the _Temple_, called _Posticum_, or _Opisthedomos_, the middle of the _Temple_, called _Cella_, or _Sacos_; the _Portico's_ or _Isles_, and the _Gate_.
