The Earth is Four Cornered like a Brick – Satapatha Brahmana 6.1.2.29

Rigveda as well as Satapatha Brahmana tells us, the earth is four cornered like a brick.^[1]The Satapatha brahmana Part. 3  Translated by Eggeling Julius (1894), page 154 – 155

The text isঃ

Here now they say, ‘Wherefore is Agni (the fire-altar) built of this (earth)?’ But, surely, when that deity (Pragâpati) became relaxed (fell asunder), he flowed along this (earth) in the shape of his life-sap; and when the gods restored him (put him together), they gathered him up from this earth: this earth then is that one brick, for Agni is this earth, since it is thereof that the whole Agni is built up. Now this earth is four-cornered, for the quarters are her corners: hence the bricks are four-cornered; for all the bricks are after the manner of this earth.^[2]6:1:2:29 Satapatha Brahmana Part III (SBE41), Julius Eggeling tr. (1894) – Sacred-texts
