Digging up the Saudi past: Some would rather not

RIYADH, Saudi Arabia — Much of the world knows Petra, the ancient ruin in modern-day Jordan that is celebrated in poetry as "the rose-red city, 'half as old as time,'" and which provided the climactic backdrop for "Indiana Jones and the Last Crusade."

But far fewer know Madain Saleh, a similarly spectacular treasure built by the same civilization, the Nabateans.

That's because it's in Saudi Arabia, where conservatives are deeply hostile to pagan, Jewish and Christian sites that predate the founding of Islam in the 7th century.

But now, in a quiet but notable change of course, the kingdom has opened up an archaeology boom by allowing Saudi and foreign archaeologists to explore cities and trade routes long lost in the desert.

The sensitivities run deep. Archaeologists are cautioned not to talk about pre-Islamic finds outside scholarly literature. Few ancient treasures are on display, and no Christian or Jewish relics. A 4th or 5th century church in eastern Saudi Arabia has been fenced off ever since its accidental discovery 20 years ago and its exact whereabouts kept secret.

In the eyes of conservatives, the land where Islam was founded and the Prophet Muhammad was born must remain purely Muslim. Saudi Arabia bans public displays of crosses and churches, and whenever non-Islamic artifacts are excavated, the news must be kept low-key lest hard-liners destroy the finds.

"They should be left in the ground," said Sheikh Mohammed al-Nujaimi, a well-known cleric, reflecting the views of many religious leaders. "Any ruins belonging to non-Muslims should not be touched. Leave them in place, the way they have been for thousands of years."

In an interview, he said Christians and Jews might claim discoveries of relics, and that Muslims would be angered if ancient symbols of other religions went on show. "How can crosses be displayed when Islam doesn't recognize that Christ was crucified?" said al-Nujaimi. "If we display them, it's as if we recognize the crucifixion."

In the past, Saudi authorities restricted foreign archaeologists to giving technical help to Saudi teams. Starting in 2000, they began a gradual process of easing up that culminated last year with American, European and Saudi teams launching significant excavations on sites that have long gone lightly explored, if at all.
