The Shulbasutras of Baudhayana, Apastamba, Katyayana and Manava: With Text, English Translation and Commentary c8.t1.6

c8.t1.6

Āpastamba (*Aśl.* 6.5, 15.4) has prescribed the same values of Baudhāyana for *īṣā*, *akṣa*, *yuga*, *puruṣa*, *vyāyāma*, *aratni* and *prādeśa*. These units of Āpastamba have been used by both Kātyāyana (*Kśl.* 2.1, 5.9) and Mānava (*Mśl.* 2.1, 4.4). The unit *pada* has been made equal to 12 *aṅgulas* by Kātyāyana (*Kśl.* 5.9). The term *vitasti* has been used in place of *prādeśa* by these two latter *śulbakāras* as well as by Kauṭilya in his *Arthaśāstra*b, while its value remains the same. Mānava (*Mśl.* 4.2-4.4) has supplied some more units, e. g. 6 *tuṇḍa*=1 *bāla* of 3 years old calf; 3 *bālas* =½ mustard seed; 2 mustard seeds=1 *yava*a; 1 *aṅgula*=6 *yavas*; and 1 *prādeśa*=10 *vitastis*.
