The Shulbasutras of Baudhayana, Apastamba, Katyayana and Manava: With Text, English Translation and Commentary c8.t4.9

c8.t4.9

**4.12-4.14.** In *ekādaśinī vedi* there are 11 posts arranged in a row, each placed at a distance of 1 *akṣa* from its immediate next. The diameter of each hole in which the pole is placed is a *pada*, and a space of 4 *aṅg.* is left on both sides of the two end-poles. Hence the space covered equals 10 *akṣa* + 11 *padas* + 8 *aṅg.* that is, 1213 *aṅg.* For the construction of the eastern part (i.e. face) of the *mahāvedi* with 11 poles, the length of 1213 *aṅg.* is divided by 24 to calculate the value of each *prakrama*. The distance between the two poles is known as *prakrama*. The length of *prakrama* varies for enlarged altars. For this reason the length of *prakrama* in *mahāvedi* is different from that of *aśvamedha vedi*. Since the face of the *mahāvedi* is 24 *prakramas*, according to Dvārakānātha, one *prakrama* equals $(10 × 104 + 11 × 15 + 4)/24 = 50 ang. 18 tilas (approx.).$
