No verbal description can give a correct idea of the elaborate workmanship of the numberless idols. One, described by Mr Stevens as the most beautiful in Copan, he considers equal to the finest Egyptian sculpture; and thinks, indeed, it would be impossible, with the best instruments of modern times, to cut stones more perfectly. They are generally from twelve to fourteen feet in height, about four wide, and two or three deep. On the front is, in all cases, a human head, with arms and hands, surrounded by the most intricate carving. Frequently other smaller heads appear below the large one. In many instances the legs and feet, as well as the body, are represented. The backs and sides are covered with the most elaborate hieroglyphics, deeply carved-- the whole forming a mass of rich ornamentation. Before several of the idols stand altars, also carved in the same finished way. The most interesting figure--which, unlike all the others, is remarkable for its simplicity--is that of a human being, bearing on its head a heavy cross-like crown. It cannot fail to remind those acquainted with the idols of Babylon of the Triune God represented in the sculptured stones of those far-famed ruins. STONE QUARRIES. Some two or three miles from the ruins are the quarries, from which the stones for the buildings and statues of Copan are evidently taken. Here still exist huge blocks of stone, in different degrees of preparation. Near a river was found a gigantic block, much larger than any in the city, which was probably on its way thither, to be carved and set up, when the labours of the workmen were arrested. It is difficult to conjecture how these vast masses were transported over the irregular and broken surface of the country, and particularly how one of them was set up on the top of a mountain two thousand feet in height. A place of this name was captured by Hernandes de Chaves at the time when its now broken monuments, ruined terraces, walls, and sculptured figures, were entire, and were all richly painted; and it seems strange that Europeans could have beheld its wonders without spreading the report of them throughout the civilised world, yet no account of this strange city was extant till it was visited by Mr Stevens.
