the possible destructive influenceof the sudden exposure to air and light, as well as damage by occasional visitors, the excavators were forced to uncover the ifnds rapidly and carry out some conservation, packaging and trans­ portation measures on the spot. In any event, though this seriously interfered with the full scientiifc docu­ mentation of the assemblage as it was uncovered in the cave, it contributed to the exceptional state of preserva­ tion of the organic material.Phase A few remains of an earlier burial were excavated under this burial.

Stratigraphy

The ifnds exposed in the cave have clear stratigraphical signiifcance, further conifrmed by the results of the 14C tests carried out on several items (Jull et al., this volume). The ifnds are attributable to three phases (from top to bottom), as follows: Phase A: A covering layer of soil mixed with much gravel and a thick layer of rock­rabbits' dung covered

Despite the initial excitement, it soon became evident that there was no connection whatsoever between these coins and the earl­ ier organic materials found in the cave. B: Under the covering upper layer, a well­preserved plaited reed mat came to light, which had been placed in the ifssure (Fig. 2.2), on the cave lfoor. Someof the mat's edges, which protruded above the rock ledge and were thus close to the surface, were damaged and poorly preserved. The mat probably padded the ifssure walls. The skeleton ofan adult male wrapped in cloth (Fig. 2.3) was discovered on the mat. The skeleton was almost fully articulated, with the exception of the skull, which was found nearby, at a distance ofc. 0.40 m from the skeleton. We could not estab­ lish with conifdence whether the skull had been intention­ ally placed next to the skeleton or whether it had been pushed aside toward the right­hand side of the cave by rodent activities (Nagar, this volume). all the material in the cave.

examination of the condition of the textile and verified through actual experimentation on small, detached frag­ ments. For example, a more concentrated glycerol solu­ tion was found to be best for treatment of the stiffer and more brittle fragments. Water, as a chemical, affects the composition of such organic materials as textiles, which contain water within their fibers and cells. This water is in equilibrium with the environment surrounding the material. When sub­ jected to aridity (as in our case), water loss results in shrinkage (Cronyn 1990:287). Water also plays an im­ portant though indirect role in the decay of porous organic materials, by conveying salts; in our case, the proximity of the cave to the Dead Sea is an unknown )though probable) factor in the deterioration of the tex­ tile. In cleaning, of course, water can have a beneficial effect, facilitating the removal of accumulated acidity, which impairs the vitality of the textile. Water provides an eiffcient medium for realigning the weave of a frag­ ment and re­establishing its shape. But water can also have a shock­effect upon very dry linen, and must be used cautiously to avoid irreversible damage. The absence of water generally provides an excellent condition for preservation, though it may have led to shrinkage and embrittlement of the organic material. In our case, the interior of the cave, with its low ceil­ ing, would temper lfuctuations of temperature and humidity. Water was an obvious choice: Its practicality was proved through experimentation, using the minute frag­ ments as trial pieces. But the use of water alone led to disintegration upon drying. To provide the water prerequisite of softening of the textile, to preserve the ifbers and to facilitate lfattening, it was necessary to

117

find a means of reducing this stress. One means was rinsing in a mixture of IMS and deionized water, thus reducing drying time (the proportion of IMS can be increased to almost 1000/0, if needed). Another means, a compromise, was to carry out both humidifying and drying very slowly. Examples follow:

fragments, all differing in condition, were treated solely with mist produced by an ultrasonic 1. Small, folded

humidifier, set for low humidity and strength. A humid­ ity chamber was set up, with the nozzle of the ultrasonic humidifier placed inside. The fragment being tested was covered with filter­paper, to protect it from dripping condensate. Lighter­colored fragments were found to require less time (as little as an hour) to soften and be opened than beige­colored fragments; beige­brown fragments often split while being opened (even after 72 hours of treatment); and brown­black fragments would collapse, regardless of length of treatment. 2. A series of a fragments of similar quality were sprayed with a softening solution of glycerol, IMS and deionized water, sprayed intermittently into the humid­ ity chamber. Though better than No. 1, the results were not satisfactory. 3. A group of fragments was treated with a solution of IMS, deionized water, and glycerol in a higher concen­ tration. It was found that the stiffer and more brittle the fragment, the longer the period of treatment re­ quired, and the higher the concentration of glycerol needed (Table 21.1). The above results are general, due to the wide range of conditions present. The precise treatment of each area was, of necessity, somewhat intuitive. The fragments and areas treated with higher concen­ trations of glycerol called for further treatment: patting with a cotton­wool wad, slightly dampened with a mix­ ture of deionized water and IMS, to draw off the excess glycerol. Glycerol evaporates very slowly, and textiles treated with it in solution need to be rinsed in a mixture of deionized water and IMS.4 A slight glycerol residue does, of course, remain; but the advantages of its use in softening brittle fabric and in preparation for opening up the textile, by far outweigh this disadvantage. The theoretical sideof selecting methodsof treatment should be stressed: (a) Do as little as possible, and with minimum intrusion; (b) organize treatment to proceed as slowly as possible; (c) allow condition to determine the time factor; though treatment should proceed slowly, its duration should also be as brief as possible; (d) be lfexible and exercise caution with regard to cleansing and softening agents; (e) be lfexible in selecting the type

Textile B: The Rectangular Cloth Initially, this piece was thought to be a corner of the large textile; after spreading it out, however, it proved to be an independent cloth (95 x 160 cm). The opening of this piece was complex and diiffcult. It was saturated with red ochre, very stiff and brittle ­ a caked, multi­

layered mass (Fig. 21.7). Little cleaning could be accom­ plished with brushes, for it was almost impossible to penetrate folds. After some hours in the humidity cham­ ber, we began opening the textile section after section, taking care to avoid over­humidification, which would have prevented the removal of the damp sand. The stronger areas were cleaned with brushes and the dirt was vacuumed up. At intervals, the chamber was opened and some of the folds could be unfolded and cleaned of sand; further softening proceeded, as described above. As soon as an area was suiffciently supple, flexible weights were placed on it (Fig. 21.8), and the textile was returned to the humidity chamber. Areas treated with higher concentrations of glycerol were specially treated to remove as much glycerol as possible.

constant complications and ruled out use ofa hermetic­ ally closed humidity chamber, though an improvised tent proved efficient. In general, treatment was the same as had been applied to Textile B. The surface of the textile was first vacuumed; the improvised humidity chamber was then constructed over the piece; light­ weight tripods resting on filter­paper were inserted to raise and support the nylon coveringof the 'tent'. The

Areas saturated with red ochre, and accordingly brittle, were very gradually flattened out, using sand­ bags of graduated weight: once an area had been softened, a light lfexible weight was placed on it. Several hours later it was replaced with a somewhat heavier one, and so on.5 To dry the textile after complete lfattening, iflter­paper was repeatedly changed above and beneath. Sandwiched in this manner, with lfexible weights over the iflter paper, and changing the paper every few hours, it slowly dried out (see Fig. 3.31).6

nylon covering was weighted down by a periphery of sand­bags. The nozzle of the humidiifer was installed within the 'tent' wherever needed, usually on one of the tripods, high above the surface. Where the condition of a particular area was weak, treatment was completed prior to beginning another area (Fig. 21.9), butif less treatment was required, work proceeded concurrently on two areas.
