When astronomers combed by means of an historic Hindu textual content often known as the Rig Veda, they found that it referenced a whole photo voltaic eclipse that occurred roughly 6,000 years in the past — making it the oldest identified point out of an eclipse.
The Rig Veda, a group of sayings and hymns from numerous spiritual and philosophical colleges, was compiled round 1500 B.C. Like almost all spiritual texts, it mentions historic occasions. Most are modern to when it was written, however some stretch again a lot additional. For instance, numerous passages within the Rig Veda point out the placement of the rising solar in the course of the vernal equinox. One reference describes the vernal equinox as occurring in Orion, and one other has it occurring in the Pleiades.
These descriptions permit astronomers to this point these references, as a result of as Earth spins on its axis, it wobbles like a spinning high, altering the relative place of vital astronomical occasions. At the moment, the vernal equinox is within the constellation Pisces. It was in Orion round 4500 B.C. and within the Pleiades round 2230 B.C., which means the Rig Veda recorded some reminiscences of occasions far sooner than its compilation.

The Rig Veda’s language is extremely symbolic and allegorical, making it troublesome to discern which tales are myths and that are historic. However two astronomers — Mayank Vahia of the Tata Institute of Basic Analysis in Mumbai and Mitsuru Soma of the Nationwide Astronomical Observatory of Japan — suppose they’ve discovered references to an historic eclipse. They reported their findings within the Journal of Astronomical Historical past and Heritage.
The passages are flowery however becoming for an eclipse, describing the solar as being “pierced” with darkness and gloom and proposing that evil beings had brought on the solar’s “magic arts to fade.” The astronomers famous that these passages don’t reference the story of Rahu and Ketu, which is a newer Hindu mythology surrounding the eclipse, indicating that these passages had been described earlier than these tales had been created.
Additional passages helped the astronomers slender down the time-frame of the photo voltaic eclipse. It occurred when the vernal equinox was in Orion, and it additionally occurred simply three days previous to an autumnal equinox. It was additionally a complete photo voltaic eclipse, and it should have occurred over the world the place the eventual writers of the Rig Veda lived.
The astronomers discovered that solely two doable dates match these standards: Oct. 22, 4202 B.C., and Oct. 19, 3811 B.C. Each of those dates are sooner than the present file holders for the oldest point out of an eclipse — a clay pill, unearthed in Syria, that recorded an eclipse in both 1375 B.C. or 1223 B.C., and a rock carving in Eire which may reference an eclipse in 3340 B.C.
The newfound reference within the Rig Veda highlights how whole photo voltaic eclipses captivated folks in antiquity and the way historic texts can contribute to our present-day data of celestial occasions.
