He also adds to Brahmagupta’s astronomy rules for computing the second component (udayāntara) of the equation of time (SŚŚ 3, 46) and the evection of the Moon (sphuṭacaraphala) (SŚŚ 11, 2–4); the latter rule, which has ultimately an Islamic Ptolemaic origin, had previously been given by Muñjāla. Śrīpati arranged the twenty chapters of the SŚŚ in much the same order as Lalla’s ŚDV, though without the latter’s division into two sections and with the addition of two chapters (13 and 14) on arithmetic and geometry (vyakta-gaṇita) and on algebra (avyaktagaṇita) respectively. The commentary, Gaṇitabhūṣaṇa, composed by Makkibhaṭṭa⁷⁸ in 1377, is preserved only up to 4, 75. - [Previous: c4.s2.64](https://indike.org/pramana/ins.science.pingree-1981.c4.s2.64) - [Next: c4.s2.66](https://indike.org/pramana/ins.science.pingree-1981.c4.s2.66) - [Up: c4.s2](https://indike.org/pramana/ins.science.pingree-1981.c4.s2) ## Linked texts (3) - [Brāhmasphuṭasiddhānta](https://indike.org/pramana/in.astro.siddhanta.early.brahmasphutasiddhanta) — Brahmagupta, Sanskrit - [Siddhāntaśekhara](https://indike.org/pramana/in.astro.siddhanta.early.siddhantasekhara) — Śrīpati, Sanskrit - [Śiṣyadhīvṛddhidatantra](https://indike.org/pramana/in.astro.siddhanta.early.sisyadhivrddhida) — Lalla, Sanskrit --- Source: [https://indike.org/pramana/ins.science.pingree-1981.c4.s2.65](https://indike.org/pramana/ins.science.pingree-1981.c4.s2.65) · Pramāṇa
