The Shulbasutras of Baudhayana, Apastamba, Katyayana and Manava: With Text, English Translation and Commentary c8.t18.2

c8.t18.2

**21.2-21-4.** *The construction.* Here the method of construction is the same as that already described in the case of the circular trough (chapter 18). We have seen that 120 *ṣoḍaśī* bricks equal 7½ sq. *pu.* 5 *ṣoḍaśī* bricks are taken out and the area of the remaining 115 *ṣoḍaśīs* (103500 sq. *aṅg.*) is turned into a square of side 321 *aṅg.* 24 *ti* (the commentator's value is 321 *aṅg.* 25 *ti*). This square is transformed into a circle of the same area as per *Bśl.* 2.9. In this act of circling the square, each of the 5 *ṣoḍaśī* bricks is cut by the circle and the western portion transferred to the eastern side. In this way, each of the 5 *ṣoḍaśī* bricks is rounded off, one of them forms the head and the remaining 4 are attached to the circle in the 4 intermediate directions (Fig. 75).
