The Shulbasutras of Baudhayana, Apastamba, Katyayana and Manava: With Text, English Translation and Commentary c8.t25.12

c8.t25.12

**12.7-12.8.** For the construction of a rhombus or two isosceles triangles on either side of the common base, Baudhyāyana’s rules, *BŚl.* 2.8 may be referred to. The seven-fold fire-altar in the form of a rhombus, with the types of bricks to be used, has been discussed by Baudhāyana (*BŚl.* 15.1-15.6). In the case of the rhombus fire-altar, the bricks are to be made as in the case of the *praugaciti*, and these should be in the form of a rhombus, as Karavinda explains (*karaṇāni cayanavidhiśca praugavat* | *viśeṣaḥtūbhayataḥ praugāḥ iṣṭakāḥ*|)
