The ruins are always spoken of as extending two miles along the bank of the river; yet all the structures described or definitely located by any visitor, are included in the much smaller area shown on Mr Stephens' plan, with, however, the following exceptions: "A stone wall with a circular building and a pit, apparently for a reservoir," is found about a mile up the river; the quarry which supplied material for all the structures and statues,--a soft grit interspersed with hard flinty lumps,--is in a range of hills two miles north of the river, where are scattered many blocks rejected by the ancient workers, one being seen on the very top of the range, and another, the largest noted, half-way between the quarry and its destination at the ruins; Fuentes' wonderful cave of Tibulca is in the same range of hills, and may be identical with the quarry, or, as Col. Galindo thinks, with a natural cave in a mountain two leagues distant; one monument is mentioned at a distance of a mile across the river on the summit of a mountain two thousand feet high, but this does not appear to have been visited; and finally, the natives reported to Mr Hardcastle a causeway in the forest, several leagues in length. Yet although so very little is known of outside monuments, there can be no doubt that such exist, not improbably of great extent and interest; since, although heaps of ruins and fragments are vaguely reported in every direction, no attempt at a thorough examination has ever been made or indeed could be, except by removing the whole forest by a conflagration during the dry season.[III-16]
The plan on the opposite page shows the ruins in their actual state, according to Mr Stephens' survey, together with a restoration to what seems to have been something like their original condition. The union of the two effects in one plate is, I believe, a sufficient reason for indulging to this extent in a fancy for restoration, justly condemned by antiquarians as a rule.[III-17]
Returning then to the limits of the plan, we find portions of a wall, _a_, _a_, _a_, which when entire, as indicated by the dotted lines, seems to have enclosed a nearly rectangular area, measuring in general terms 900 by 1600 feet. Whatever treasures of antiquity may be hid in the depths of the forest, there can be but little doubt that this enclosure embraced the leading structures or sacred edifices of the ancient town. These walls would seem at least twenty-five feet thick at the base, and are built, like all the Copan structures, of large blocks of cut stone, of varying but not expressly stated dimensions. They are built, in parts at least, in terraces or steps, and painted. Only one authority speaks of the use of mortar.[III-18]
