Astronomical Evidence on the Age of the Rgveda
Summary
The article examines the age of the Rgveda by analyzing astronomical evidence from Vedic texts, particularly the Taittiriya-Samhita, Tandya-Brahmana, and Kausitaki-Brahmana. The main argument is that these treatises belong to different periods, as evidenced by their differing rules for year-beginnings and intercalated months, which reflect distinct Nakshatra epochs. The Taittiriya-Samhita and Tandya-Brahmana favor the Krttika epoch, beginning the year at the Magha full moon or the Ekastaka, while the Kausitaki-Brahmana reflects a later Mrgasiras epoch, preferring the Pausa month and explicitly detailing the thirteenth intercalary month. This discrepancy suggests a gap of about a thousand years between the compositions. The article also discusses the Pole Star, noting Jacobi's identification of Alpha Draconis as the Dhruva pole star around 2780 B.C., which supports the antiquity of Vedic rituals. Winternitz challenges this interpretation of the Satapatha-Brahmana, arguing the Pleiades remained visible in the east around 1100 B.C. The text further reviews scholarly views on the origin of the Nakshatra system, rejecting foreign influence in favor of an indigenous Indian development, and debates the art of writing in ancient India. While Max Muller argues for a purely oral tradition due to the absence of writing references, the author suggests that the vast Vedic prose literature and the discovery of the Indus script imply that writing was known, at least during the Brahmana period.

Conclusion
The article argues that the age of the Rgveda can be determined by analyzing astronomical data embedded in Vedic texts and Brahmanas. Key findings include the identification of distinct Nakshatra epochs—such as Krttika, Mrgadiras, and Punarvasu—which correspond to specific year-beginning months like Magha, Pausa, and Caitra. By comparing the Taittiriya-Samhita, Tandya-Brahmana, and Kausitaki-Brahmana, the study reveals a chronological gap of approximately one thousand years between these treatises, challenging earlier assumptions that they belonged to the same period. The significance of these findings lies in their ability to establish a precise timeline for Vedic antiquity, supporting the theory that the Rgveda dates back to at least 3000 B.C. Furthermore, the analysis of intercalary months and the precession of the equinoxes provides robust astronomical evidence, reinforcing the high antiquity of Vedic civilization and its sophisticated understanding of celestial mechanics.
