Antiquities of the Mesa Verde National Park: Cliff Palace

by Jesse Walter Fewkes

As the kiva is the men's room, and as religious exercises are largely controlled by men, such ceremonies occur in kivas, which are practically the ceremonial rooms.[45]

KIVAS OF THE FIRST TYPE

All kivas of the first type are constructed on the same general plan, the different parts being somewhat modified by surrounding conditions. While their general form is circular or cylindrical, some are square with rounded angles, others oblong, and others more or less heart-shaped. Their diameter and height vary according to circumstances, but this type is always subterranean when possible, even though excavation in the rock may be necessary.

The walls of the kivas are sometimes double, and the masonry is generally well constructed. The walls show evidences of plastering, which is decorated in some instances with paintings or incised figures. The number of pilasters is commonly 6, but 4 and 8 are also evident; rarely, as in kiva M (the subtype), all are missing. Between these pilasters are the so-called banquettes, one of which is usually larger than the others. The banquettes are generally built 3 or 4 feet in height, consequently they could scarcely have been intended for seats.

The pilasters are commonly rectangular, sometimes square, the size being about uniform from base upward. In rare instances a pilaster has a cubby-hole[46] in one side. Where circumstances require the ventilator penetrates the rear portion of the pilaster, but the flue never enters the side of the kiva under a pilaster.

The pilasters, which are almost universal in kivas of the first type, as has been shown in the description and illustrations of the eight kivas of Spruce-tree House, served as supports for the roof beams. These rafters of pine rested upon and served to support other logs laid one over another, so that finally the roof opening was covered. Across the middle of the walls, at the top, two long parallel logs were placed, in order to add stability to the roof structure. These beams were set far enough apart to allow a hatch midway between their ends, which served the purpose of an entrance and also permitted the escape of smoke from the fire directly below.

Over the framework of logs were laid small sticks, filling the interstices, and above these was spread a layer of cedar bark; the whole was then covered with clay, thus bringing the upper surface of the roof to the level of the adjacent plaza. Whether the kiva walls projected above the plaza and roof level is unknown, but possibly they did, and there may have been a slight elevation of the hatchway, as in the Hopi kivas. It is commonly believed that the kiva roof was level with the surrounding plaza and that the entrance was through a hatchway, but no depression or other sign of a ladder or of its resting place on the kiva floor has yet been found in any of the Mesa Verde ruins.

The floors of the kivas are commonly of hardened adobe; unlike those of the Hopi kivas they are never paved with stones, but the natural rock often serves for that purpose. It is not rare to find the surface of solid rock that forms the kiva floor cut down a few feet to a lower level. Although generally smooth, when the floor is the natural rock there are sometimes found in it small, cup-like, artificial depressions similar to those in the horizontal surfaces of the cliff or in slabs of detached rock.

The fire-pit, which is found in all kivas of the first type,[47] is a circular depression situated slightly to one side of the middle of the room. While generally lined with adobe, slabs of stone sometimes form its border, and it is also to be noted that one or two of these small stones sometimes project above the floor level. The fire-hole is sometimes deep, and is generally filled with wood ashes, indicating long use.

Every kiva of the first type has a lateral passageway for the admission of air, opening into the chamber on the floor level, generally under the large banquette. This passage, or tunnel, here designated a flue, communicates either directly with the outside or turns upward at a right angle and forms a small vertical ventilator which opens at the level of the plaza. Between the entrance into the flue from the kiva and the fire-hole there rises from the floor a device called the deflector (sometimes called an altar), the object of which was to prevent flames and smoke being drawn into the ventilator, or to evenly circulate the inflowing fresh air in the chamber. This deflector may be (1) a low stone wall, free on both ends; (2) a curved wall connected with the kiva wall on each side with orifices to allow the passage of air; (3) a stone slab in the kiva floor; (4) a bank, free at each end, supported by upright stakes between which are woven twigs, the whole being plastered with clay.[48]
