XV.9 XV. SECRETS OF ASTRONOMY 285 7. Though the Sun is low near the horizon, near sunrise or sunset, the Moon, being higher up, can hide the Sun like a cloud. VM here answers an objector to his stand (5-6). He is unaware that the case in (7) is similar to that (5-6). TS’s emendations paramocca, which means ‘standing high up in the sky’, will make an eclipse itself impossible. NP’s emendation candroparasamavastha does not give the sense of ‘being under the Moon’ given by them for the expression. अस्माकमुदयसमये येषामल्पास्तगो दिवसनाथः । मध्याह्नो वा येषां तेषामपि न युगपद्ग्रहणम् ॥ ८ ॥ तदतीतमुदयगानां क्षणद्वये (नैष्य)दस्त(देशा)नाम् । मध्याह्नदे(श)गानामनवरतं वर्तमानेन ॥ ९ ॥ 8. For people who have sunset and for people who have mid-day, when we have sunrise, for all of us, the solar eclipse does not occur at the same time. 9. Throughout the time when there is eclipse for the mid-day people, it is past for the sunrise people by four nāḍikās, and will be yet to occur for the sun- set people by four nāḍikās. The context is the solar eclipse and the Moon is near the Sun, So for the sunrise people the apparent longitude of the Moon has increased by parallax, and the circumstances of the eclipse are advanced by more than four nāḍīs. The opposite happens for the sunset people, and the circumstances are delayed by four nāḍīs. The duration itself is shortened by a slow rate of change of parallax for both. Therefore when the mid-day people’s eclipse begins, the morning people’s eclipse has ended, and when it ends, the evening people’s eclipse has not begun. So there is no overlapping of them. The explanation given by me is general, and several other circumstances will have to be taken into account. But VM’s statement is correct in a general way. Hindu astronomers give the maximum parallax converted into time as four nāḍīs. We must contrast this with the lunar eclipse, which begins and ends at the same moments, wherever the Moon is visible on the earth. 7a. A.B. यद्यं (B. द्य) द्युदये; C. ग्रासे ह्युदये 8a. B.
