     Stonehenge may have been a prehistoric health center rather than a site for observing stars or a temple

in honor of the dead, scientists said yesterday. New evidence unearthed at the World Heritage Site in more

than 40 years suggests that the monument was a place where the diseased and injured went in groups,

seeking cures.

     After a two-week dig, scientists have concluded that Stonehenge was "the ancient healthcare centre of

southern England" because of the existence of "bluestones"-the smaller columns of dolerite (辉绿岩) that

formed an earlier stone structure.

     By dating pieces of remains to around 7330BC, Tim Darvill, of Bournemouth University, and Goff

Wainwright, of the Society of Amtiquaries have found that hunter-gatherers were at the site on Salisbury

Plain 4,000 years earlier than thought. The first stage of Stonehenge, a round earthwork structure, was

built around 3000BC. Professor Wainwright added: "I did not expect the degree of complexity we discovered.

We're able to say so much more about when Stonehenge was built and why-all of which changes our

previous understanding of the monument."

     The research reveals the importance of the henge's famous bluestones. Hundreds of bluestone chips

gathered at the site have led the team to conclude that the bluestones were valued for their curing effects-the

key reason that about 80 of them, each weighing up to 4 tons and a half, were dragged more than 150 miles

from the Preseli Hills to Wiltshire. After years of research, Professors Darvill and Wainwright have

concluded that, for thousands of years, the Preseli mountain range was home to magical health centers and

holy wells.

      Even today there are those who believe in the curing powers of the springs for coughs and heart disease,

and people who use crystals and bluestones for self-curing. Radiocarbon tests have also revealed that the

construction of the original bluestone circle took place around 2300BC, three centuries later than originally

thought. Interestingly, on the same day died the "Amesbury Archer"-a sick traveler from the Swiss or

German Alps who had an infected knee-whose remains were discovered about five miles from Stonehenge.

The professors believe that he was a devoted religious person who was hoping to benefit from the curing

powers of the monument.
