Roy elaborates further on this example, stating that when 'the sun became united with Orion at the vernal equinox...[this] commenced the yearly [YajnaVaraha] sacrifice'. The vernal (March) equinox marks the onset of spring, and is celebrated in Indian culture as the Holi festival (the spring festival of colours).

I.G. Pearce states that the Satapatha Brahmana - along with other Vedic texts such as the Vedas, Samhitas, and Tattiriya Samhita - evidences 'the astronomy of the Vedic period which, given very basic measuring devices (in many cases just the naked eye), gave surprisingly accurate values for various astronomical quantities. These include the relative size of the planets the distance of the earth from the sun, the length of the day, and the length of the year'. A.A. Macdonell adds that the Satapatha in particular is notable as - unlike the Samhitas -  in it the Earth was 'expressly called circular (parimandala)'.

In the construction of fire altars used for sacrifices, Kak also notes the importance of the number, configuration, measurements, and patterns of bricks representing factors such as: 

Vedic Meters: The rhythmic structure of verses in sacred utterances or mantras, particularly from the RigVeda
Area/size and numeric equivalences: Units of time such as Muhurtas, months, seasons, and days; and Vedic numerology, an example being the Falcon altar (see left image), which was constructed from five layers of 200 bricks each, the total 1,000 bricks symbolising the Purusha, the first principle of creation, enumerated in the RigVeda (10.90):

Notably, P. N. Sinha states that the number 1,000 represents 'the thousand Maha yugas of every Kalpa' (about 4.32 billion years), illustrated by the 1,000 hoods of the Naga Vasuki/Ananta on which the Earth is supported. I.G. Pearce, F. Staal, and D.M. Knipe all agree with Kak, repeating that the number, layering, size, and configuration of bricks to construct sacrificial altars - real and symbolic - as detailed in texts such as the Satapatha
relation to the constellation of Orion. Roy elaborates further on this case, express that when' the sun became united with Orion at the youthful equinox... [this ] commenced the yearly [ YajnaVaraha ] forfeit'. The youthful (March) equinox marks the onset of spring, and is celebrated in Indian polish as the Holi festival (the spring festival of colours). 

 I.G. Pearce submit that the Satapatha Brahmana - along with early Vedic texts such as the Vedas, Samhitas, and Tattiriya Samhita - evidences' the astronomy of the Vedic time period which, given very basic measuring device (in many cases just the naked center), gave surprisingly accurate value for various astronomic quantities. These include the relative size of the planets the distance of the earth from the sunlight, the length of the day, and the length of the year'. A.A. Macdonell adds that the Satapatha in particular is notable as - unlike the Samhitas -   in it the Earth was' expressly called circular (parimandala)'.
