The Shulbasutras of Baudhayana, Apastamba, Katyayana and Manava: With Text, English Translation and Commentary c5.s2.25

c5.s2.25

In the *Śatapatha Brāhmaṇa*, the same measure of the *mahāvedi* as given in the *Taittirīya Saṃhitā* has been adopted.i The *kāmya agnis* such as the *suparṇa garutman*, the *droṇacit*, the *rathacakracit*, the *kaṅkacit*, the *praugacit*, the *ubhāyata praugacit* etc. have been described here.j These *kāmya citis* all measure 7½ sq. *puruṣas*. Regarding the areas of the fire-altars, the *Śatapatha Brāhmaṇa* observes, “According to one (school), *ekavidha agni* should be constructed first, then by an increment of one (*square puruṣa*) successively upto a construction of an unlimited size. But indeed the *agni* (or *Prajāpati*) was to be constructed first as *saptavidha* (7½ sq. *puruṣas* and then by the increment of one square *puruṣa*) in succession is to be made upto *ekaśatavidha* (101½ sq. *puruṣas*)”a Compare this with Baudhāyana’s and Āpastamba’s statements in their *śulbasūtras*b that one fold means 1½ sq. *puruṣas*, two-fold means 2½ sq. *puruṣas*, seven-fold means 7½ sq. *puruṣas* and so on. This has also been explained by other *śulbakāras*.
