XVIII.5 XVIII. VĀSIṢṬHA-PAULIŚA – RISING AND SETTING 315 TABLE I Motion on the synodic circle (computed)
| Superior conjunction | Retrograde begins | Retrograde ends |
|---|---|---|
| 30 days 37½° | 9 d. −2¼° | 243 d. 258 ° |
| Rising West | 5 d. −2½° | Setting East |
| 60 d. 74 ° | Setting West | 30 d. 37½° |
| 60 d. 73 ° | 5 d. −2½° | Superior conjunction |
| 60 d. 68¼° | Inferior conjunction | Total 514 d. 575½° |
| 27½ d. 26¼° | 5 d. −3° | |
| 12½ d. 9¼° | Rising East | |
| 17 d. 7 ° | 5 d. −2½° | |
| 6 d. ¼° | 9 d. −2¼° | |
| Next, 1¼° for 23 days is too too small to be correct. Further, the correct total of days and degrees | ||
| clearly given by the numbers will be spoiled by this. So I have given the meaning as 5¼° in 17 days, | ||
| which fairly agrees with the actuality, by introducing a (vi) for the defect of two mātrās and emending | ||
| sapādāṃśaṃ into sapādārdhān. | ||
| Since the motion only 15′ for the 6 days near the stationary point as seen in the actual, the siddhānta is | ||
| justified in combining this with the −2° 13′ for the next 9 days and giving −2° for 15 days. But, for the | ||
| next 5 days, the motion is almost −2½° and not −2°, and this is an observational error. For the 5 days | ||
| forming the half period of invisibility till the inferior conjunction, the actual motion is about −3° but we are | ||
| constrained to make it −2° for agreement with the other numbers, especially when it is left to be under- | ||
| stood, no motion being given by the text. A glance at the comparative table will make everything clear. | ||
| TS have made the serious mistake of thinking that the segments given begin with the | ||
| superior conjunction instead of the rising on the west (vide the scheme given in the Sanskrit | ||
| Commentary, p. 98). By the total of 610 days, they have given that the rising takes place 26 | ||
| days after superior conjunction, passing 22½°, which is absurd because it should be 37½° in 30 | ||
| days, i.e. half the time and degrees given for the time from setting to rising. They do not realise that | ||
| this is the period of the quickest motion. Within the scheme they get the 77° for 85 days, by making | ||
| a drastic change in the wording of the text. Further, for 85 days in that part, the motion would be | ||
| more than 91°. Giving 1¼° for 3 days near the stationary point is wrong since it should be practi- | ||
| cally zero. −4° for 5 days in retrograde is too great. But they have given the same −4° for the 10 | ||
| days in the ativakra region where the rate should be the greatest. | ||
| As for NP, they have correctly interpreted that in the three 60-day periods after rising, the | ||
| motions are 74°, 73° and 72°, that from setting in the east and rising in the west there are 75° for | ||
| 60 days, half before the superior conjunction and half after, and that near the inferior conjunction | ||
| there are 50 days of retrogression and −12°, half of each falling on each side of the point, as given | ||
| by the text. Adding these we can account for 250½° in 235 days. Since we should get 287¾° for | ||
| the 292 days from the superior to the inferior conjunction, we have still to account for 37¼° in 57 | ||
| days. This we must seek in the second half of verse 3. By some likely emendations we can secure | ||
| this, as I have done. But NP have drastically changed the text as | ||
