The Porch was a place covered at the Entrance at the greatest part of _Temples_, being as broad as the whole _Temple_. There were three sorts of them. Some were surrounded with Pillars on three Sides; Others had only Pillars in the Front, the Sides of the Porch being made up by the continuation of the Side-Walls of the _Temple_; Others were made up at the Sides, partly by Pillars, and partly by the Continuation of the Side-Walls of the _Temple_. The _Posticum_ of the _Temple_ was equal to the Porch, having likewise a Gate, but all Temples had not _Posticums_, though almost every _Temple_ had its _Pronaos_, or Porch. The Middle of the _Temple_, called _Cella_, was a place inclosed with four Walls, having no Light but at the Gate, unless it were uncovered, as we shall shew hereafter. The _Portico's_ which make the Isles, were ranks of Pillars, sometimes single, sometimes double, which stood along the Sides of the _Temple_ on the out-side: some _Temples_ wanted this part. The Gates of the _Temples_ were different according to the difference of the Order of the Architecture, according to which the _Temple_ was built: there was the _Dorick_, the _Ionick_, and the _Attick_. The height of the _Dorick_ Gate was taken by dividing into 3 parts and an half, the space which is from below to the bottom of the _Plat-fond_ of the _Portico_, which _Platfond_ was called _Lacunar_: they allow'd 2 to the height of the Gate under the _Lintel_: this height was divided into 12 parts; 5 and an half were taken for the breadth of the Gate below, for above it was straiter by a 3d. part. A 4th. part, and even an 8th. part of the _Chambranle_ or _Door-Case_, according to the height of the Gate, which was to be less straitened above, the higher it was. The breadth of the _Chambranle_ or _Door-Case_, was the 12th. part of the height of the Opening of the Gate. The _Chambranle_ or _Door-Case_ grew straiter and straiter towards the top, _viz._ the 4th. part of its breadth: it was only edged with a _Cymatium_, with an _Astragal_. Upon the _Cymatium_ above the _Chambranle_ or _Door-Case_, was a _Frise_ called _Hyperthyron_, which had the same breadth with the _Chambranle_ or _Door-Case_. Upon this _Frise_ was placed a _Dorick Cymatium_, with a _Lesbian Astragal_; both of them jetting out very little. Upon the _Moulures_ the _Flat-Crown_ was placed, with its little _Cymatium_, which jetted out the whole breadth above of the _Chambranle_ or _Door-Case_, with its Mould.
