The Intervall betwixt the Trench and Work.
The Work it self; in the inmost part whereof, there is a stone appearing not much above the surface of the earth, (and lying towards the East) four foot broad, and sixteen foot in length. Which, whether it might be an _Altar_ or no, I leave to the judgement of others, because so overwhelmed with the ruines of the Work, that I could make no search after it, but even with much difficulty, took the aforesaid proportion thereof. Yet for my part, I can apprehend no valid reason to the contrary, except that the whole constructure being circular in form, the Altar should rather have been placed upon the center of the Circle, then enclining to the circumference. Neverthelesse it cannot be denied, but being so sited, the _Cell_ (as I may call it) was thereby left more free, for the due performance of those severall superstitious rites, which their Idolatry led them to. Besides, though the _Altare_ amongst the _Ancients_ was exalted and raised somwhat high above the earth; yet, their _Ara_ was made quadrangular, not very high, and as some will have it close to the ground, being consecrated as well to the supernall as infernall Deities: and therefore in respect of the form, it may hold well enough it was anciently an Altar.
The great stones which made the entrances from the outside of the Trench, seven foot broad, three foot thick, and twenty foot high.
The parallel stones, on the inside of the Trench, four foot broad, and three foot thick; but they lie so broken, and ruined by time, that their proportion in height cannot be distinguisht, much lesse exactly measured.
The Groundplot of the work, as when first built, in a greater form, with the foure equilaterall triangles making the _Scheame_, by which the whole work was composed.
The six principall entrances, three whereof directly opposite to those of the Trench.
The stones which made the outward Circle, seven foot in breadth; three foot and an half thick, and fifteen foot and an half high: each stone having two tenons mortaised into the _Architrave_, continuing upon them, throughout the whole circumference. For, these _Architraves_, being joynted directly in the middle of each of the perpendicular stones that their weight might have an equall bearing, and upon each side of the joynt a tenon wrought, (as remains yet to be seen) it may positively be concluded thereby, the _Architrave_ continued round about this outward circle.
