Here, also, was found a very beautiful fragment of one of the friezes, representing a female figure stepping into a chariot, the face of which, happily but slightly injured, retains even now the finish of a cameo. Mr. Newton’s next plan of ascertaining, if possible, the boundary-wall of the _temenos_ was a happy one, as he thus, at once, discovered a mass of marble blocks, piled one above another, and intermixed with fragments of statues; and thus unearthed, (1) a colossal horse, in two pieces, and part of the head of another horse, with the bronze bridle still adhering to it; (2) a lion in fine condition, and another in two pieces; (3) a draped female figure broken in half; (4) a head of Apollo. All these sculptures were found heaped together, and had evidently not been disturbed since they had fallen. The conclusion was inevitable, that parts of the colossal horses of the quadriga from the top of the monument had now been met with; and that this quadriga and much of the pyramid, its support, had been simply hurled upon and over the wall of the _temenos_, and that Mr. Newton had, in fact, found them just as they had fallen, it may be 1,700 years ago.[39] Near to the horse’s head, too, was found a face of a colossal male head, presumably that of some personage connected with the quadriga, and, from its general style, which is analogous to the idealized portrait of Alexander the Great on the coins of Lysimachus, most likely from a statue of Mausolus himself. The face has a noble expression, and by a happy accident, the outlines of the features have remained uninjured. Though we have no actual evidence on this subject, it is probable that the statue we have called Mausolus was standing in the chariot at the top of the monument. On the south side of the building Mr. Newton found several portions of what, when put together, were clearly parts of one of its wheels. The fragments consisted of part of the outer circle, half the nave, and a piece of one of the spokes. The wheel, originally, had six spokes, the alternate intervals between each spoke having been closed to ensure by its solidity the strength of the whole wheel. As what has been found shows that the wheel was 7.7 inches in diameter; and as the horses could scarcely have been less than 10 feet in length, we may fairly suppose the top of the pyramid on which the quadriga stood was at least 24 feet long. From other calculations it may be shown that the pyramid was 23½ feet high: but for these and other similar details we must refer our readers to Mr. Newton’s work on the Mausoleum. Footnote 39: It is reasonable to conjecture that the first ruin of the Mausoleum was due to the earthquakes of the first and second centuries A.D., to which we have already alluded.
