Jyotihshastra: Astral and Mathematical Literature c3.38

c3.38

The Āpastamba, which is divided into six *paṭalas* and twenty-one *adhyāyas* (3 *adhyāyas* in *paṭalas* 1, 3, and 5, 4 in *paṭalas* 2, 4, and 6), presents essentially the same material as does the Baudhāyana, though with fewer variations on the basic forms of the altars, in 223 *sūtras*. It was commented on by Kapardisvāmin,²⁴ who apparently lived before 1150 (Kapardibhāṣya); by Karavindasvāmin,²⁵ who has followed Kapardisvāmin (*Śulbapradīpikā*) and quotes from the Āryabhaṭīya; by Gopāla²⁶ (*Rahasyaprakāśa*); and by Sundararāja, the famous Kerala astronomer of the end of the fifteenth century (Sundararājīya).
