Of the outer wall of the circular building the most interesting portion is decidedly that to the south-east. A few courses below the summit on the outside, from point A to point B on the plan, runs the pattern, formed by two courses having the stones placed chevron-wise, neatly fitted in with smaller stones receding a little, so as to make the pattern at a distance appear as if it stood out in relief, whereas it is really flush with the wall. This pattern coincides with the sacred enclosure inside, terminating at point B exactly where the enclosure terminates, and at the other end at point A about half-way down the narrow passage, forming thus an arc of one and a half right angle. Its connection with the sanctity of the place is obvious, and into its relation to the orientation of the temple Mr. Swan will enter fully in the ensuing chapter. Along this portion of the wall, and on this only, large monoliths were inserted, most of which have fallen away; but those still standing show that they were equidistant. Here too the top of the wall has been neatly paved with slabs of granite, and must have formed a broad promenade, presumably approached by steps from a point near the main entrance. Here one can still walk with ease, whereas on the inferior portion of the wall it is now scarcely possible to scramble. The labyrinthine character of the interior will be best grasped by a glance at the plan. Entering from the northern portal, we at once plunge into its intricacies. The great and astounding feature is the long narrow passage leading direct from the main entrance to the sacred enclosure, so narrow in parts that two people cannot walk abreast, whilst on either side of you rise the stupendous walls, thirty feet in height, and built with such evenness of courses and symmetry that as a specimen of the dry builder’s art it is without a parallel. The large blocks of cut stone used in Egyptian, Greek, and Roman masonry must have been comparatively easy to deal with as compared with these small stones of rough granite built in even courses in a circular wall of immense thickness and height. The idea at once suggests itself that the people who erected these walls had at one time been accustomed to build in bricks, and that in the absence of this material they had perfected a system of stone-building to represent as nearly as possible the appearance of brick; also another reason for the use of small stones may have been to enable them to construct the tower and curves with greater accuracy. The facings of the stones are all uniform, but most of them run back into the wall irregularly, acting in the same way as throughs in our dry-built walls at home in preserving the building from falling. In this narrow passage, at point S, is the remarkable hole, executed with perfect neatness through the thickest part of the wall, about the actual use of which I am able to give no definite theory. It
