212 ASTRONOMICAL CONSTANTS Manda and sighra epicycles of the planets : 26-28(i). The manda epicycles (of the same planets) are 32, 14, 60, 70, and 28 (degrees) respectively; and the sighra epicycles are 72, 260, 40, 234, and 132 (degrees) respectively. The Sun's apogee and epicycle are the same as those of Venus (i.e., 80° and 14° respectively). The Moon's epicycle in the midnight day-reckoning is stated to be 31 (degrees). Positions of the so called manda and sighra pātas of the planets : 28(ii)-31(i). (The following directions for) the degrees of the (manda and sighra) patas of the planets as devised (under the midnight day-reckoning) should be noted carefully by learned scholars. Add 180° to the longitudes of the mandoccas (apogees) and sighroccas of Mercury and Venus, and subtract 3 signs from the mandoccas (apogees) and sighroccas of the remaining planets. Then are obtained the longitudes of the manda and sighra patas of the planets. (Also) add 2 degrees to the longitudes of the manda pātas and sighroccas of Venus, Satura, and Jupiter; and 1 degrees to those of Mars and Mercury. (It should be noted that) the sighra patas have been stated for all the planets excepting Mercury. (Mercury does not have a sighra pāta).¹ That is to say, the longitudes of the manda-patas of Mars, Mercury, Jupiter, Venus, and Saturn are 21°5, 41°-5, 12°, 262°, and 152° respectively; and the longitudes of the sighra-patas of Mars, Jupiter, Venus, and Saturn are (sighrocca - 88°-5), (sighrocca - 88°), (śighrocca + 182°) and (sighrocca - 88°) respectively. 1 This passage represents rather old ideas of Hindu astronomy. The conception of manda and sighra pātas does not occur in any other work. Our translation agrees with the interpretations given in the various commentaries. The translation given by P. C. Sengupta in the intro- duction to his Khaṇḍa-khādyaka is wrong.
