The first exhibits that portion of the façade toward the north end of the building. The tail of one serpent is held up nearly over the head of the other, and has an ornament upon it like a turban, with a plume of feathers. The marks on the extremity of the tail are probably intended to indicate a rattlesnake, with which species of serpent the country abounds. The lower serpent has its monstrous jaws wide open, and within them is a human head, the face of which is distinctly visible on the stone, and appears faintly in the drawing. From the ruin to which all was hurrying, Don Simon cared only to preserve this serpent's head. He said that we might tear and out carry away every other ornament, but this he intended to build into the wall of a house in Merida as a memorial of Uxmal.

The second engraving represents the two entwined serpents enclosing and running through the ornaments over a doorway. The principal feature in the ornament enclosed is the figure of a human being, standing, but much mutilated. The bodies of the serpents, according to the representations of the same design in other parts of the sculpture, are covered with feathers.

The two engravings represent about one fifth of the whole façade; the other four fifths were enriched with the same mass of sculptured ornaments, and toward the south end the head and tail of the serpents corresponded in design and position with the portion still existing at the other. Had it been our fortune to reach this place a few years sooner, we might have seen the whole entire. Don Simon told us that in 1835 the whole front stood, and the two serpents were seen encircling every ornament in the building. In its ruins it presents a lively idea of the "large and very well constructed buildings of lime and stone" which Bernal Dias saw on landing at Campeachy, "with figures of serpents and of idols painted on the walls."

At the end of the courtyard, and fronting the gate of entrance, is the façade of a lofty building, two hundred and sixty-four feet long, standing on a terrace twenty feet high. The ascent is by a grand but ruined staircase, ninety-five feet wide, flanked on each side by a building with sculptured front, and having three doorways, each leading to apartments within.

The height of this building to the upper cornice is twenty-five feet. It has thirteen doorways, over each of which rose a perpendicular wall ten feet wide and seventeen feet high above the cornice, making the whole height forty-two feet from the ground. These lofty structures were no doubt erected to give grandeur and effect to the building, and at a distance they appear to be turrets, but only four of them now remain. The whole great façade, including the turrets, is crowded with complicated and elaborate sculpture, among which are human figures rudely executed: two are represented as playing on musical instruments, one being not unlike a small harp, and the other in the nature of a guitar; a third is in a sitting posture, with his hands across his breast, and tied by cords, the ends of which pass over his shoulders. Of the rest there is nothing which stands out distinct and intelligible like the serpent, and the whole, loaded as it is with ornament, conveys the idea of vastness and magnificence rather than that of taste and refinement.

This building has on curious feature. It is erected over, and completely encloses, a smaller one of older date. The doorways, walls, and wooden lintels of the latter are all seen, and where the outer building is fallen, the ornamented cornice of the inner one is visible.

From the platform of the steps of this building, looking across the courtyard, a grand view presents itself, embracing all the principal buildings that now tower above the plain, except the House of the Dwarf. The engraving opposite represents this view. In the foreground is the inner façade of the front range of the Monjas, with a portion of the range on each side of the courtyard. To the left, in the distance, appears the Casa de la Vieja, or of the Old Woman, and, rising grandly above the front of the Monjas, are the House of the Turtles, that of the Governor, and the Casa de Palomos, or the House of the Pigeons.
