Oldest Known Record of Total Eclipse Is Younger Than Thought, Study Says
Scientists missed by 150 years in dating the oldest known reliable record of a total solar eclipse, a clay tablet that also reflects fear among the ancient observers, researchers said today. Scientists had concluded about 20 years ago that the eclipse, recorded on a clay tablet found in Syria, occurred on May 3, 1375 B.C. But in today's issue of the British journal Nature, two Dutch scientists report their analysis shows the eclipse really happened about 150 years later, on March 5, 1223 B.C. The tablet was found in 1948 in the ruins of Ugarit, an ancient city near Syria's Mediterranean coast. One side appears to tell of a solar eclipse, and the reverse side reads, ``Two livers were examined: danger.'' ``Apparently the anxiety caused by the eclipse of the Sun and the sudden appearance of Mars had to be resolved by an explanation through liver divination,'' wrote the researchers from the University of Amsterdam and Leiden University. They concluded that the earlier text analysis of the tablet misidentified the time of year in which the eclipse occurred. The new study indicated the eclipse really happened in late February or early March. In addition, the text apparently indicates that Mars was visible at the time of the eclipse, the Dutch researchers said. They compared those criteria and the likely age range for the tablet to a list of possible total solar eclipses visible from Ugarit. Only the event in 1223 B.C. fills the bill, the researchers said. In an accompanying editorial, Christopher B.F. Walker of the British Museum in London cautioned that their conclusion ``can best be regarded as a plausible hypothesis.'' The translation of the tablet's text is not certain, and the study assumes that citizens of Ugarit followed an Egyptian-style calendar, for which no supporting evidence is available, he said. Even if the tablet is 150 years younger than previously believed, it would remain the oldest known reliable record of a total solar eclipse, Edwin Krupp, director of the Griffith Observatory in Los Angeles, said in a telephone interview. The next-oldest record was made in China in the Eighth Century B.C., said Krupp, a researcher in ancient astronomy.
