“Another broad street runs close to the main street, from the trench mentioned, toward the east, for about a quarter of a league, ending at a small hill which overlooks the town, on whose summit is a circular wall, not unlike the curb of a well, about a full fathom in height. The floor within is paved with cement, as the city streets. In the centre is placed a socle or pedestal of a glittering substance, like glass, but of what composition is not known. “This circular structure was the tribunal or consistory of the Cakchiquel Indians, where not only was public hearing given to causes, but also the sentences were carried out. Seated around this wall, the judges heard the pleas and pronounced sentences, in both civil and criminal causes. After this public decision, however, there remained an appeal for its revocation or confirmation. Three messengers were chosen as deputies of the judges, and these went forth from the tribunal to a deep ravine, north of the Palace, to a small but neatly fitted up chapel or temple, where was located the oracle of the demon. This was a black and semi-transparent stone, of a finer grade than that called _chay_ (obsidian). In its transparency, the demon revealed to them what should be their final decision. If it was that the sentence should be confirmed, the accused was immediately executed on the central pedestal mentioned, which also served as a place of torture. If, on the other hand, nothing could be seen in the transparency of the stone, the accused was forthwith discharged. This oracle was also consulted in all their military undertakings; and war was declared or not, as it seemed to dictate, as is stated both by Spaniards and the oldest natives. But in the early days of our occupation, when these facts came to the knowledge of the Reverend Bishop Don Francisco Marroquin, of glorious memory, he gave orders that this stone should be artistically squared, and he consecrated it and used it as an altar stone, and at this day it is so employed on the grand altar of the convent of _San Francisco de Tecpan goathemala_, and it is considered a jewel of unusual beauty and value. The size of the stone is a full half yard in each direction. “The principal gate of this stronghold or citadel was upon the causeway mentioned; and they say it was closed with two doors set in the solid wall, the external one opening outward, the internal one inward, and both were of the stone called _chay_. Thus, one of these doors backed up against the other, as we sometimes see double doors in our prisons. They were always guarded with double guards, one within, the other without, and these guards were changed every seven days. In the open country, on the other side of the ravine, there were a number of mounds, about a quarter of a league apart, extending for a considerable distance. On these, lookouts were constantly stationed, to give notice of the invasions of the Quiches or of the Sotojil king.”
