"THE MYSTERY OF STONEHENGE" TO BE SEEN ON "CBS NEWS RETROSPECTIVE" The Mystery of Stonehenge," an award-winning exploration of the origins of the mysterious ruins on England's stark Salisbury Plain, south of London, will be rebroadcast on "CBS News Retrospective" Sunday, Aug. 12 (6:00-7:00 PM, PT) on the CBS Television Network.

Produced by the late Harry Morgan and originally broadcast on the Network on Feb. 1, 1965, "The Mystery of Stonehenge" that year won an Ohio State Award and a George Foster Peabody Award.

Stonehenge, clusters of monolithic stones forming a unique pattern, for centuries has been a source of speculation over who built it, how it was built, and, most important, why it was built. Located in Wiltshire, it is one of Great Britain's prime tourist attractions.

In June 1964, Dr. Gerald Hawkins, an astronomer at the Smithsonian Astrophysical Observatory in Cambridge, Mass., proposed that the original function of Stonehenge was to serve as an astronomical observatory and a crude computer, basing his theory on solar and lunar calculations for approximately the year 1,500 B.C.

The astronomical alignments of the concentric stone circles were checked scientifically, along with the 56 peripheral "Aubrey holes" --so named for the antiquary who first investigated them. The results, shown on the broadcast in a unique sequence filmed at dawn as the sun rose over the great stones, indicate that the monument could have been used by Stone Age people to calculate a 19-year eclipse cycle.

CBS News Correspondent John Hart, host of the retrospective series, points out that in the eight years "since 'The Mystery of Stonehenge' was originally broadcast, Hawkins' theory has been challenged, mainly by Robert Newton and Robert Jenkins of John Hopkins University.

"They say the 56 Aubrey holes probably had no astronomical meaning at all to the people who built Stonehenge," Hart adds. "Since all the other stone circles in Britain have different numbers of Aubrey holes, it's just as likely that the holes stood for the number of families in the clan."

None of the theories since Hawkins' has been accepted as definitive, however. So, as Hart says on the broadcast, "For those of you who are romantic, Stonehenge can remain a mystery."

CBS News Correspondents Charles Collingwood and Alexander Kendrick are the reporters on "The Mystery of Stonehenge." Robert Chandler is the executive producer, and Peter Poor is the producer of "CBS News Retrospective."
