Toilet tied to tale of Dead Sea Scrolls

One of the less sanitary aspects of life in Jesus' day has come into play in the debate over who wrote the Dead Sea Scrolls, how they lived and how they died.

The latest evidence comes from a site that two researchers have identified as the communal latrine for Qumran, the ancient settlement near the caves where the 2,000-year-old scrolls were found.

Israeli anthropologist Joe Zias and James Tabor, a biblical scholar at the University of North Carolina at Charlotte, say the unusual placement of the latrine would be consistent with the theory that Qumran was inhabited by a hard-core Jewish sect known as the Essenes. They even speculate that the latrine's unsanitary conditions may have contributed to ill health among the sect's members.

The prevailing view among archaeologists has been that Essenes at a Qumran monastery were the keepers of the Dead Sea Scrolls — but that view has come under increasing challenge in recent years, with some experts saying Qumran was a fortress or a pottery-making center that had nothing to do with the Essenes.

One of the most vigorous critics of the Essene connection, University of Chicago historian Norman Golb, told MSNBC.com that the latest report from Tabor and Zias "does nothing" to prove that the Essenes lived and worked in Qumran.

"The recent finding of a latrine can, at the most, show no more than that the inhabitants of the area were human beings who practiced some form of sanitation," Golb said.

So what do ancient potty practices have to do with the mystery of Qumran? Although the findings of Zias and Tabor may not be a smoking gun, they represent an intriguing blend of textual analysis and "CSI"-style forensics — intriguing enough to be accepted for publication in Revue de Qumran, an international journal on Dead Sea Scroll science.

Toiletries in texts
It all started with Tabor's reflection on historical texts: The book of Deuteronomy, as well as the Dead Sea Scrolls themselves, considered bathroom duties to be unclean in the sight of God. Thus, the faithful were told that their latrines had to be placed far enough away from the community to be out of sight. Various references specify distances of 1,000 to 3,000 cubits (1,500 to 4,500 feet, or 457 to 1,370 meters), preferably to the northwest of the community.

According to the 1st-century historian Josephus, the Essenes in Jerusalem strictly observed this custom. He marveled at the Essenes' religious and intestinal fortitude, noting that they refused to "go to stool" on the Sabbath — and Tabor speculated that this was because the latrine was farther away than Jews were allowed to travel on the holy day.

Years ago, it struck Tabor that Essenes at Qumran should have had a similar practice. "I thought, 'They must have been doing this if they believed it so fervently. Has anyone ever gone out and looked for this?'" he recalled.

Looking at a map, Tabor saw there was a prime site about 1,640 feet (500 meters) northwest of the Qumran site, sheltered from view behind a bluff. When he walked up to the site, he could see that one area of soil had a significantly different coloration. But how could he prove that it was a latrine, where the Essenes felt it was their religious duty to dig a trench, do their business and shovel dirt back on top?

That's when Tabor called upon Zias, a "bioarchaeologist" who has taken on other biblical puzzles such as the mechanics behind Roman-style crucifixion.

Parasites in ancient poop?
Zias took 10 soil samples — four from the site identified by Tabor, and six from elsewhere in the area as control samples — and had them analyzed by Stephainie Harter-Lailheugue, a French parasitologist from the Centre National de la Recerche Scientifique.

Three of the four samples from the suspected latrine contained desiccated eggs from parasitic worms commonly found in human stool samples (tapeworms, roundworms and pinworms). Meanwhile, none of the control samples turned up evidence of human-specific parasites.

Zias said that would indicate "heavy and continual use" of the site as a latrine.

Usually, the parasites in fecal matter would die out due to exposure to the elements in the Dead Sea region, Zias said. That's what happens to the waste left behind by modern-day Bedouins, for example. But Zias said the Essenes' practice of covering up their waste may have actually preserved the parasites.

Yet another curious twist strengthened the Qumran connection: Similar traces of parasites were found in a soil sample taken from inside the settlement, at a spot that Zias and Tabor think served as an emergency restroom for the Essenes.

As he put together the story, Zias came around to the view that Qumran was actually a pretty unsanitary place to live. "This should be a warning to religious people that you can take things a little bit too far," he told MSNBC.com.
