C
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:Rosin. lib. 2. and therefore in respect of the form, it may hold well enough it was anciently an Altar.
D
The supposed Altar.
E
The great stones which made the entrances from the outside of the Trench, seven foot broad, three foot thick, and twenty foot high.
F
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.
G
The scale of fifty foot.
