Harare, Zimbabwe ? Tudor Parfitt has spent years chasing a theory that a lost tribe of Jews wound up in Southern Africa. But his latest leap has landed him in a minefield.

The subject at hand is this British scholar’s contention that the remains of a 700-year-old bowl-shaped relic which he tracked down in a Zimbabwe museum storeroom in 2007 could be a replica of the Ark of the Covenant that carried the Ten Commandments.

According to African legend, white lions of God and a two-headed snake guarded the “drum that thunders” in a cave in southwestern Zimbabwe’s sacred Dumbwe mountains. Parfitt’s theory has sparked fierce reactions from some Zimbabwean scholars, who suspect a plot to superimpose foreign origins on what is purely a product of African culture.

Tudor Parfitt, professor of Modern Jewish Studies at the University of London’s prestigious School of Oriental and African Studies, looks at the remains of a 700-year-old bowl-shaped relic that he thinks could be a replica of the Ark of the Covenant on Feb. 19 at the Harare Museum of Human Sciences in Zimbabwe.

Having long disappeared from public view since its discovery in the 1940s, the artifact is now on display at the Harare Museum of Human Sciences. It is about 45 inches by 24 inches in diameter and 27 inches tall with a pattern of shallow engraving on the outside that could have held gold threads. Scorch marks on the base inside were possibly left by primitive gun powder.

Parfitt, a professor of Modern Jewish Studies at the University of London’s prestigious School of Oriental and African Studies, says he first heard of the vessel during his two-decade search for Jewish tribes lost in Africa.

At the center of that research is a southern African ethnic group variously called Lemba, Remba or waLemba. Parfitt says 52 percent of them carry a Y chromosome known as the Cohen Modal Haplotype (CMH) — unique to ancient priestly Jewish communities and raising the possibility they are descended from Aaron, Moses’ brother. Other groups in Zimbabwe have no CMH.

The waLemba are also set apart from other tribes by such Jewish customs as observing a weekly Sabbath, practicing circumcision, shunning pork and slaughtering animals by methods similar to Jewish kosher rules.

Parfitt acknowledges that theories counter to his are “wholly plausible,” and the museum is careful not to take sides. The materials accompanying the exhibit that opened this year outline both the theories behind the relic.

One says the original Ark of the Covenant may have been destroyed when the Babylonians invaded Jerusalem in 586 B.C., that several copies likely were made and that one was taken to Ethiopia by Prince Menelik, the son of Solomon and the Queen of Sheba. Another could have found its way to ancient Zimbabwe, says the exhibit.

The other posits that it is a purely African relic, and that according to legend, was made by waLemba craftsmen for royal elders to give them magical powers.

In the Zimbabwean Shona language, the artifact is called “Ngoma Lungundu,” the “drum that thunders”; the waLemba call it “the voice of God.”

Parfitt says that according to oral tradition, the waLemba could have been among peoples who left Judea in biblical times and migrated through Yemen to east Africa, Ethiopia and beyond, bringing the ark with them.

Eminent Zimbabwean historian Rob Burrett disputes Parfitt’s theories.

“He is on the wrong track. Wooden drums — ceremonial drums and war drums with great powers similar to those attributed to the ark — are an integral part of African culture,” Burrett said.

The genetic test “doesn’t prove anything,” he said, noting that early European explorers of the east African coast found a strong presence of Arab and Jewish traders moving into the African interior. “These people were certainly not celibate and would have created mixed-blood communities along the way,” he said.

African traditionalists believe the Ngoma is a royal drum so powerful that it imploded and was rebuilt on the original wooden base 700 years ago. Indeed, a splinter from the top of the artifact has been carbon-dated to about 1300, making it probably the oldest surviving wooden object in southern Africa.
