Microscopic Traces<br />

The def<strong>in</strong>ition of what one is try<strong>in</strong>g <strong>to</strong> determ<strong>in</strong>e is desirable before<br />

an analysis. I will attempt <strong>to</strong> answer two very basic but unconsidered<br />

questions. Are <strong>the</strong>re microscopic particles associated with <strong>the</strong><br />

scrolls? If <strong>the</strong>re are, can <strong>the</strong>se particles be characterized utiliz<strong>in</strong>g<br />

analyses based on <strong>the</strong> <strong>light</strong> microscope?<br />

The material selected was pieces of cellophane tape that had been<br />

removed by <strong>the</strong> Dead Sea Scrolls labora<strong>to</strong>ry of <strong>the</strong> Rockefeller<br />

Museum, Jerusalem. At <strong>the</strong> time of <strong>the</strong>ir discovery, <strong>the</strong> scholars<br />

study<strong>in</strong>g <strong>the</strong> scrolls used cellophane tape <strong>to</strong> jo<strong>in</strong> <strong>to</strong>ge<strong>the</strong>r <strong>the</strong> many<br />

fragments of <strong>the</strong> manuscript.<br />

The glue side of <strong>the</strong>se pieces was scanned utiliz<strong>in</strong>g a stereo microscope<br />

at various magnifications between 6.3 and 40 diameters. Fibers<br />

and microscopic particles of apparent <strong>in</strong>terest were manually removed,<br />

and analyzed utiliz<strong>in</strong>g a polarized microscope at magnifications<br />

between 100 and 630 diameters.<br />

In addition <strong>to</strong> <strong>the</strong> cellophane tape pieces, which were felt <strong>to</strong> be<br />

heavily contam<strong>in</strong>ated by particles of modern orig<strong>in</strong>, two jars associated<br />

with <strong>the</strong> scrolls and on display at <strong>the</strong> Shr<strong>in</strong>e of <strong>the</strong> Book of<br />

<strong>the</strong> Israel Museum were exam<strong>in</strong>ed. These jars were selected because<br />

<strong>the</strong>y had been found whole, ra<strong>the</strong>r than reassembled <strong>from</strong> fragments<br />

that had been washed, and had covers on <strong>the</strong>m. The two jars were<br />

overturned over clean paper and tapped <strong>light</strong>ly. The material fall<strong>in</strong>g<br />

out of <strong>the</strong> jars on<strong>to</strong> <strong>the</strong> paper was analyzed. The analysis followed<br />

<strong>the</strong> same stereo and polarized <strong>light</strong> microscope scheme outl<strong>in</strong>ed above.<br />

Many particles and fibers were found on <strong>the</strong> cellophane tape pieces.<br />

Not every particle or fiber was characterized, but <strong>the</strong> follow<strong>in</strong>g classes<br />

of material were identified: a) hair fragments, human and wool; b)<br />

pollen particles; and c) syn<strong>the</strong>tic and natural fibers. Some of <strong>the</strong><br />

wool fibers were dyed. The natural fibers consisted ma<strong>in</strong>ly of flax<br />

and cot<strong>to</strong>n, with some of <strong>the</strong> cot<strong>to</strong>n be<strong>in</strong>g dyed.<br />

Many particles and fibers were retrieved <strong>from</strong> <strong>the</strong> jars. Aga<strong>in</strong>, not<br />

every fiber or particle was characterized. Hair fragments, <strong>in</strong>clud<strong>in</strong>g<br />

human, animal and wool, were identified. Some of <strong>the</strong> wool fibers<br />

were dyed and one of <strong>the</strong> animal hairs appears <strong>to</strong> be cat of nonmodern<br />

orig<strong>in</strong>. Pollen gra<strong>in</strong>s and <strong>in</strong>sect parts were also present <strong>in</strong><br />

<strong>the</strong> material <strong>from</strong> <strong>the</strong> jars as well as syn<strong>the</strong>tic and natural fibers.<br />

The natural fibers aga<strong>in</strong> consisted of mostly cot<strong>to</strong>n and flax, with<br />

some of <strong>the</strong> cot<strong>to</strong>n be<strong>in</strong>g dyed.
