XVIII.28 XVIII. VĀSIṢṬHA-PAULIŚA – RISING AND SETTING 333 An examination of the rate shows that the perigee is situated at the end of the Makara (Capricorn) and the apogee at the end of Kaṭaka (Cancer), which both fairly agree with the actual. TS say that they do not understand this verse, and no translation is given; its place being taken by a question mark. NP translate thus: “In the first gati 240 plus 28 minus 1/2 (= 267 1/2) (days). One should calculate days for every two signs from Pisces.” It is clear that they do not see that this verse gives the detailed rate of motion of the Type I gati in the diads of rāśis from Pisces, as affected by the equation of the centre. They think that the first motion given in verse 25, which 186° according to them, takes 267 1/2 days, as given by them here. If so, what use is the instruction to calculate for “every two signs from Pisces”? 'विषय-[रस-] खर-(रस-)र्तु-पञ्चका[न्] 'दशगुणान् द्वि[ती]यगतौ | सहितान् 'स्वरैकपक्षर्तु-चन्द्र-शीतांशुभिः' क्रमशः || २८ || 28. The II type motion, in the same order, (i.e. for each month of the diads, Pisces–Aries, etc.) for the 18° take 5 × 10 + 7, 6 × 10 + 1, 7 × 10 + 2, 6 × 10

• 6, 6 × 10 + 1, and 5 × 10 + 1 days. This gives 57 days each to move in the signs Pisces–Aries, 61 days for each of Taurus-Gemini, 75 days for each of Cancer-Leo, 66 days for each of Virgo-Libra, 61 days for each of Scorpio-Sagit- tarius, and 51 days for each of Capricorn-Aquarius. From the days given, it can be seen that there is a slight tilt in the apogee towards Leo, and in the perigee towards Aquarius. This small difference from the findings in verse 27 shows that the values are empirical. As for the readings, rasa has been inserted because we want six numbers for the six diads, and one is wanting. Symmetry requires that it must be rasa (= 6) there. Also two mātrās are wanting. sapta is emended into rasa because, 76 for Virgo-Libra, with 72 on one side, and 61 on the other side, will take the apogee to the end of Virgo, 60° off from its place. The average for II type motion is 18° for 81 days which is about the average of the mean rate and 0 (stationary). Thus I type motion is faster than the mean, and the II type slower, as we have sur- mised. TS have expressed inability to interpret this verse also, and not translated it. Yet they have made an emendation which need not be taken seriously, since it has been done without understanding. NP have interpreted the verse as giving 57, 71, 72, 66, 61 and 51 by inserting ṛtu as the fourth. But symmetry shows that the second number 71 is wrong, and it must be 61, to avoid the jump from 57 to 72. At any rate, read with their interpretation of verse 27, we can see that they do not under- stand the use of this series of numbers. They do not even say these are days. 28a.
