The first layer of verification concerns the author’s identity. Varāhamihira is mentioned by name in the works of later Indian scholars, most notably (10th century), who wrote a detailed commentary on the Bṛhat Saṃhitā . More importantly, the text itself cites earlier authorities (e.g., Āryabhaṭa, Parāśara, Garga) and is cited by later astronomical works like the Pañcasiddhāntikā (also by Varāhamihira). The consistency of technical terminology—especially the use of the siddhāntic planetary models and the unique 60-year Jovian cycle —across his known corpus strengthens the case for common authorship. Thus, verification here is bibliographical : the authorial attribution is consistent with the intellectual milieu of 6th-century Ujjain, a known center of jyotiṣa .
Some modern enthusiasts claim to have “verified” Varāhamihira’s predictions of earthquakes (Chapter 32) or planetary colors (Chapter 3). Such claims are pseudoscientific. When Varāhamihira states that an earthquake preceded by a red halo indicates a coming war, this is a cultural correlation, not a testable hypothesis. Verification in the modern empirical sense would require controlled, repeatable observations—which are impossible for unique historical events. Thus, to speak of “Varāhamihira verified” as a scientific claim is a category error. The text is a compendium of traditional knowledge, not a lab manual.
The Brhat Samhita states: “When ants carry eggs, when the crow bathes in dust, and when the rainbow appears in the west—rain is imminent within 48 hours.” Biometeorologists have verified these biological indicators. Ants move eggs to higher ground (rising humidity). Crows dust-bathe to remove parasites before rain increases humidity. This is not superstition; it is phenology—the study of periodic biological phenomena. The verification accuracy stands at 85% for short-term forecasts.

The text acts as an early manual for agricultural planning. Chapters on Megha Shastra detail cloud classification, wind patterns, and rain metrics. Varahamihira tracked early signs of monsoon patterns up to six months in advance by evaluating: Cloud colors and density. Atmospheric halos and lightning frequencies.

The (literally the "Great Collection") is a monumental 6th-century Sanskrit encyclopedia authored by the polymath Varahamihira during the Gupta Empire's "Golden Age". Serving as his magnum opus, this 106-chapter treatise is far more than a book of astrology; it is a holistic record of ancient Indian scientific and cultural life. The Story of the Polymath's Legacy
Varahamihira describes the Rahu (shadow planet) model for eclipses. While today we know eclipses are caused by the Moon’s node, his computational algorithm for the duration and magnitude of a solar eclipse was tested against known eclipses from 500–600 CE. The Brhat Samhita’s formulas predict eclipse timings within a 15–20 minute margin of error – remarkable for naked-eye astronomy.
📍 He refined the calculation of the vernal equinox and was among the first to suggest that the Moon shines by reflected sunlight. Explain his astrological predictions ? Compare his work to modern science ? Such claims are pseudoscientific
: He was the first to propose that termites and certain plants could serve as bio-indicators for finding underground water, a method modern science has since explored.
The most robust verification of the Brhat Samhita comes from its astronomical sections, which are deeply indebted to the Surya Siddhanta .
