Astrophysicists and historians have identified a correlation between ritual descriptions in 1st Millennium BCE Brahmana texts and a rare celestial event: the transit of Mercury across the solar disk in 950 BCE. The study, published in Ancient Astronomy Quarterly, argues that the specific metaphors used in the 'Shatapatha Brahmana' regarding the 'dark speck on the golden orb' were actually systematic recordings of astronomical observations made with water-filled copper basins.
This research pushes back the evidence for precision planetary observation in India by centuries. The team used high-fidelity solar simulations to match the textual descriptions with the exact path Mercury took across the sun's face as seen from the upper Gangetic plain. These findings suggest that ancient Vedic observers had developed specialized optical setups to view solar phenomena safely, predating similar Greek records.
