In the large second trench I have brought to light a second wall of smaller stones, 12 feet high, which runs parallel with the great circuit wall, and thus forms a curve of about the third part of a circle. It enters the adjoining field, which is now being excavated, and its direction parallel with the great circuit wall seems to have been unintentional. It is not, however, vertical, but its western face slopes at an angle of 75 degrees with the horizon, like the great tower of Ilium. It deserves attention that here and there we see in this wall wrought flat slabs, which give the impression that the wall belongs to a later period than the Cyclopean circuit wall. On this wall are two parallel rows of large, closely-joined slabs of a calcareous stone, which show the same inclination as the wall, and appear to form, with the part in the adjoining field, a full circle. If so, the wall, on which these rows of slabs stand, can only have been built for the purpose of supporting them in this lower part of the Acropolis, and of raising them to the level of their prolongation on the much higher neighbouring ground. It deserves particular attention that on the inner side of the supposed circle, namely, on the side towards which the parallel rows of slabs incline, the vacant space has evidently been filled up with _débris_ to the very top of the wall immediately after its completion.[200] [Sidenote: THE THIRD SCULPTURED TOMBSTONE.] I frequently found here, at a depth of from three to four feet, ashes of burnt animal matter, also masses of bones of animals, but no bones which I can identify as human, for no skull has turned up. The space between the two slanting parallel rows of slabs was filled with _débris_, mixed with innumerable fragments of beautiful archaic pottery, and a great many Hera-idols, but no bones were found there. Within the curve, and very near to the two parallel rows of slabs, I brought to light two more sculptured tombstones of a hard calcareous stone (see Nos. 141, 142), one of which is in the same line with the two sculptured slabs which I have already described, and only 1 ft. 5 in. south of them. It is 3 ft. 8¾ in. broad at the base, and 3 ft. 7½ in. at top; 6 in. thick, and 4 ft. 2 in. long; and thus the line of the three tombstones together is 13 ft. 8 in. long. This newly discovered third tombstone (No. 141) shows, like the two others, on its western side, a sculpture in bas-relief, which is divided by a horizontal fillet into two compartments, and is encompassed on all sides by two parallel fillets. Of the upper part of the stone a piece, apparently about one foot high, is missing. In the upper compartment is represented a warrior, whose head and neck are not now visible on account of the breaking of the stone. He is represented standing on a chariot drawn apparently by only one horse[201], the outstretched hind and fore legs and the uplifted tail of which seem to
