Vedic texts contain interesting astronomical lore. The Vedic calendar was based upon astronomical sightings of the equinoxes and solstices which change periodically owing to the precession of the earth on its axis. Such texts as Vedanga Jyotish(*38) speak of a time when the vernal equinox was in the middle of the constellation (Nakshatra) Aslesha (a point about 23 degrees 20 minutes Cancer). This would have occurred around 1400 BC. Many Brahmanas, and the Yajur and Atharva Vedas speak of the vernal equinox in the Krittikas (Pleiades; early Taurus) and the summer solstice (ayana) in Magha (early Leo).(*39) This yields a date of around 2500 BC. Yet earlier astronomical eras than these are mentioned but these two have numerous references to substantiate them. They prove that the Vedic culture existed at the time of the Harappan culture and already had a sophisticated system of astronomy.

Such references were merely ignored or pronounced unintelligible by Western scholars because they yielded too early a date for the Vedas than what was presumed, not because such references did not exist. One point raised by Western scholars was that there was nothing archeological to substantiate such positions and the dates reveal. Now we see there is indeed that archeological evidence through the Harappan or Sarasvati civilization.

Had such astronomical references been found in ancient Greek texts, we might add, they would have been hailed as great scientific achievements, among the greatest of ancient humanity. It is only because they occurred in Hindu texts that they have not been given proper credit. On the contrary we are told that the Hindus were unscientific, which has often been an excuse to ignore the scientific achievements mentioned in the Vedas.

Recently Subhash Kak has also discovered an astronomical code in the structure of the Rig Veda that shows a knowledge of the periods of the planets, as well as reflecting a location for the hymns around 22 degrees north, or the point where the Sarasvati used to enter the ocean.(*40)
