पञ्चसिद्धान्तिका (आचार्य वराहमिहिर - सूर्य, रोमक, पौलिश, वासिष्ठ एवं पितामह सिद्धान्त)

320 PAÑCASIDDHĀNTIKĀ XVIII.13 seem to think, that the three sectors are each taken wholly to get intermediate values by interpola- tion. An examination of the total of each sector would show how wrong it would be. The true eq. cent. corrected Jupiter is given for the end of any pada we want. We are expected to use these to get the true motion through any segmentation of the total padas, for correct interpolation, and the ends of the segments may fall anywhere, from pada 0 to pada 390. Therefore the small pada seg- ments are used. I shall work out an example at the end to make everything clear. I shall explain the rationale of the instruction in verse 8, of adding or subtracting the difference. The eq. cent-corrected Jupiter is subtracted from the Sun to get the anomaly of conjunction. So, a positive eq. cent. means less anomaly of conjunction. The days left over represent the anomaly of conj. with the 399 days of the synodic period, corresponding to 360° of anomaly. So the day is taken as roughly equal to the degree of anomaly, and the difference in degree subtracted. Vice versa for the eq. cent. corrected Jupiter, it being less then the mean. Varāhamihira is too astute to confuse day and degree, as NP think. (In verses 64-81 too, there is no confusion in the author's mind, as NP seem to think. There he has deliberately chosen the time taken by the Sun to move one degree as the unit of time, and call it 'day', for convenience. This is patent on the face of the synodic periods given, though TS have not even seen it, and are perplexed. We have reason to think that verses 64- 81 are by somebody else). दिन (षष्ट्यांशान्) द्वादश 'खकृतैर्वे (दान्)' 'कृताश्विभिर्द्वौ च । सप्ताष्टकेन वक्री षड्[भागान्] षष्टितः षट् च ॥ १२ ॥ अनुव(क्रो) ऽशीत्यार्का (न्' द्व्यू) नार्ध (श) तेन नव ततोऽस्तमितः । स्थित्वा सैकं मासं स्फुटोद (योऽष्टोत्तरैरङ्गैः) ॥ १३ ॥ ॥ बृहस्पतिः ॥ 12. By 60 days, (Jupiter moves) 12°, by 40 days 4° and by 24 days 2°. Becom- ing retrograde, by 56 days he moves 6° (i.e. -6°) and by 60 days, 6° (i.e. -6°). 13. Following after retrograde, he moves 12° in 80 days, and 9° in 48 days. Then setting, staying so for a month plus one day, he clearly rises moving 6° 8'. Ends Jupiter. The Scheme given
