Cistern Feature Description

Given the importance of water in any food system it is not surprising that cisterns are one of the more important, and ubiquitous features in the survey region. Unfortunately most cisterns are nearly impossible to record accurately. It is especially difficult to determine the dimensions of the inner chambers. While seeking to gather this data, be especially careful that you do not fall into the cistern.

A. No. of Chambers

If you can safely determine the number of chambers in the cistern, place the total in this space.

B. Material

The material should always be limestone, but if by chance there is some other material, describe it in the blank following "Other."

C. Facing

In this section, mark the entry "Unfaced" if the cistern wall shows no signs of an exterior or interior lining. If there any signs of plaster, check the space next to "Plaster." If mud, check the space next to "Mud." Very rarely you may find traces of paint on plastered walls. If the paint is in the form of a design, make sure the architect draws it, and whether or not there is a design, be sure to enter the Munsell color.

D. Plan

In this section describe the floor plan of the cistern. If the cistern is basically "Rectilinear," mark the third space. If round, mark "Circular." An "Oval" cistern can be elliptical or egg-shaped, as well as oval. An "Apsidal" cistern has three linear walls connected in a "U" shape and one semi circular wall which forms an apse at the open end of the "U." "Irregular" indicates amorphous shapes which cannot be grouped. When there are no qualifiers, an "a" is placed in the entry blank and you imply that the feature's plan is very close to the ideal. Most cisterns will be circular, square, or irregular.

E. Tooling

On cistern walls, look for signs of "Tooling." If there are tool marks, enter the width of the tool mark in cm and a range of lengths. Make a quick sketch of tool marks, checking the space labeled "Sketch" and file it with the Feature Sheet. Make sure photos are taken of all types of stone cutting in each feature, then check the "Photo" entry.

F. Dimensions

The nature of cisterns in the survey region often prevents entry by the recorder. In these cases accurate measurement will be impossible. If you were able to enter the cistern, check the space following the label "Meas[ured]." If you were unable to enter sufficiently for measurement but sufficiently to make dimensional estimates, check the space following the label "Est[imated]." Most cisterns will have debris covering their floors. If possible, estimate the "Depth of Debris." The contents of this debris may help determine what a cistern has been used for. If it was impossible to even estimate any or all pertinent dimensions, leave these spaces blank. In the space following "Remarks," be sure to include the reason why you were unable to make accurate measurements of the feature.

G. Principal Opening

This portion of the description section deals with the shape of the principal opening that gives access to the cistern. Note both the shape and the dimensions of the opening in the appropriate spaces.

H. Secondary Opening

Cisterns usually have secondary openings which are used for the collection of runoff water. Much smaller than the primary opening to the cistern, these can be difficult to locate. If you are able to locate this opening, fill in the appropriate blanks and in the remarks section describe this opening's spatial relationship to the main cistern opening.

I. Cistern Floor

The material on the floor of a cistern is usually the best indication of its present function. Generally a mix, determine the relative percentages of these materials on the surface of the cistern's floor and mark the appropriate spaces.

J. Preservation

Place an "X" in the appropriate blank. If you are unable to enter a cistern to determine the degree of preservation, place an "X" next to the label "U.D." and explain this on the "Remarks" line.

K. Capstone

Many cisterns have their openings blocked by a "Capstone." These are composed of various types of materials; we have encountered everything from concrete plugs to the hoods of automobiles. When recording a cistern, place an "X" in the appropriate space.

L. Cistern Use

Cisterns usually enjoy a long period of use, and although the advent of deep well technology in the survey region has changed water procurement strategies, many are still in use today. If this is the case, check the space beside "Presently In Use." If the cistern appears usable but is not being used, check the space beside "Presently Out of Use." If the Cistern has "Collapsed," mark the appropriate space. Cisterns are sometimes reused, often as herding pens, after their collapse. If this is the case, place an "X" in the appropriate space and describe its new use.

M. Remarks

The "Remarks" section belongs to the overall description of the feature. You may want to record subtleties which are not included in the specific entries above. If so, please give a thoughtful, concise, and specific description.
