Motion of Venus
76. Deduct 1,18,122 from the 'days'. Multiply by 2 and divide by 1151. Take
the remainder and divide by 2. We have the 'days' from the conjunction of
Venus.
77-78. In 5 'days' Venus lags by 9°, and rises in the east. In 15 days it lags 21°.
In 64 days it lags 15°. In 164 days it gains by 35°. Then it sets in the east. Then
in 40 days it gains 10°, and joins the Sun. Then, moving in accordance with
the reversed order of the days for cycles given, it rises, after the days given
from setting to conjunction (i.e., 40 days), in the west, and moves till it reaches
the setting in retrograde (and getting into the inferior conjunction) section.
Note 1. I have corrected mitīndu into dhṛtīndu for agreement with the Sun in superior conjunction
which alone fits. TS's correction (also NP's) mahīndu does not bring agreement with the Sun either
at superior conj. or inferior conj. There can be another possible correction matīndu (mati is 8). In
the 64 days, flanking the retrograde, the days may be a little more or less, since a small error of
observation can produce a difference of a large number of days. The lacunae is filled by me with
sapañcakāstriṃśat, meaning 35°, to fit the number of degrees wanted to make up the total zero, and
fitting the number of days given. TS's emendation, kṛtāṣṭabhiḥ will be far from fitting the total.
