REFERENCE TO ARYABHATA These two verses show that Brahmagupta was not hostile to Arya- bhata when he wrote this Khandakhadyaka; he merely intends presenting the subject matter on simple lines and furnishing the results obtained by Aryabhata in a simpler way. In the following verse of the same chapter, he refers to Aryabhaṭa's midnight day-reckoning systein: The mean Saturn diminished by 3 seconds, the Sighrocea of Mercury diminished by 22 seconds, the mean Mars increased by 2 seconds and the mean Jupiter increased by 4 seconds are equal to the respective mean planets of Arya- bhaṭa's "midnight-system".¹ 53 In the Appendix of the Khandakhadyaka known as Khanda- khadyakottara, we again find a few verses where the name of Aryabhata occurs; Three of these verses have been reproduced from the Brahmasphutasiddhanta (BrSpSi I. 62, 63; II.47) : Aryabhata made the apogee of the Moon as moving more quickly and the node as moving more slowly than their actual motions; if his constants give correct results in rela- tion to the end of tithis [i. e. conjunction etc.] or eclipses. they must be considered as accidental as are the letters cut into wood by weevils. (KK. IX.1; BrSpSi. I. 62) On seeing me, who possess the most accurate knowledge of mean motions, men who have learnt from the works of Srişena, Vişnucandra and Aryabhata, cannot face me in any meeting just like deer on seeing a lion (KK. IX. 2; BrSpSi. I. 63) As the apparent planets beginning with Mars as derived from the works of Srişena. Aryabhata and Vişnucandra, are far deviated from their true places, the works of these authors are therefore not valued among the learned.² (KK. IX. 3: BrSpSi. II. 47) 1. तिसृभिः शनिईशीघ्र द्वाविंशत्या कुजोऽधिको द्वाभ्याम् । चतसृभिरधिको जीवोऽर्द्ध' रात्रिकार्यभटमध्यसमाः ।! 2. अकृतार्यभटः शीघ्रगमिन्दूच्वं पातमल्पगं स्वगतेः । तिथ्यत ग्रहणानां घुयाचरं तस्य संवादः ||१|| मध्यगतिक्षं वीक्ष्य श्रीषेणार्य्यभट विष्णुचन्द्रज्ञाः । सदसि न भवन्मयभिमुखाः सिंहं दृष्ट्वा यथा हरिणाः ||२|| दूरभ्रष्टाः स्पष्टाः श्रीषेणार्य्यभटविष्णुचन्द्र षु । यस्मात् कुजादयस्ते विदुषां नैवादरस्तस्मात् ||३|| - KK.I.7 - KK.
