THE INDIAN ANTIQUARY
OCTOBER, 1924
about İth of a radi. It is just probable that such a slight difference might have been caused by the Astronomical systems of those early centuries. Dewan Bahadur L. D. Swamikannu Pillai also agreed with me on this point, when recently we had a talk on the subjeot.
(2) 10th March. A.D. 680, Kali 3780.--This date was pointed out by F. Kielhorn. This fulfils all the requirements.
(3) 11th March, A.D. 776, Kali 3875.-Dr. Burnell after consulting an Astronomer pointed out A.D. 774, but certainly he must have meant 775. This is also correct. (4) 15th March, A.D. 1320, Kali 4420.- This is also pointed out by Kielhorn.
We now have four dates which suit the Astronomical requirements. One of them must be the date required.
The date of Parkara Iravi.-We must here discuss the date of Parkars fravi Varmar also, whose inscriptions form a subject of comparison with the Vira Raghava plate. The date of Pårkara Iravi can be fixed with certainty on Astronomioal grounds.--
We have a fairly large number of inscriptions of his time. Some of them giving regnal years or age and the positions of Jupiter. I give below a list of those inscriptions with the years and respective positions of Jupiter.
The Perunna inscription of the 14th year11 Jupiter in Makara (10th Rabi). The Tirukkotittanam Inscription No. 2, 13th year Jupiter in Itavam (2nd Rasi). The Tirkkákkara Inscription No. 3, 31st year Jupiter in Dhanu (9th Raci). The Perunna Inscription 33rd year Jupiter in Itavam (2nd Radi). The Tirunelli oopper plate 46th year Jupiter in Chinnam (5th Radi). The Tirukkakkara Inscription No. 5, 58th year Jupiter in Chinnam (5th Radi). The Tirunelli plate No. 2, 43rd year Jupiter in T'uldm (7th Rasi).
It will take nearly a year for Jupiter to travel one rasi and nearly 12 years to travel the whole rafichakram (ecliptic) of 12 rasis. The 13th and the 31st year inscriptions may go together. The 33rd, 46th and 58th year inscriptions may also go together. The 14th year inscription stands alone, so does the 43rd year inscription also. These four kinds of insoriptions cannot be reconciled. The 14th and the 13th year inscriptions cannot be reconciled because in the 14th year Jupiter was in the 10th rasi and in the 13th year it was in the 2nd rafi. Then again the 14th year inscription and the 33rd year inscription cannot be rooonoiled, because there is a difference of 19 yours between them, and Jupiter will return to the 10th rafi after 11 or 12 years and in the course of the remaining 7 or 8 years it should reach the 5th or the 6th rati, but it is in the 2nd rafi. The 14th year and 43rd year inscriptions cannot be reconoiled, because out of the 29 years of difference 23 or 24 years are required for it to come back to the 10th raki. The remaining 5 or 6 years will bring it to the 3rd or 4th rasi, but it is in the 7th rabi. Then the 31st year inscription, which may be reconciled with the 13th year insoription, cannot be reconciled with the 33rd year inscription, because in the 31st year Jupiter was in the 9th rdéi and in the 33rd year it was in the 2nd rabi. Again the 33rd, 46th and 58th year insoriptions which may go together oan. not be reconciled with the 43rd year inscription; because in the 43rd year Jupiter was in the 7th rabi and in the 46th year it was in the 5th råsi. If the years given are all regnal years, there must have been four Parkara Iravi Varmars. In case we suppose that in some of them the regnal years and in others the ages are given, these may be reduced to two. Anyhow from the style, language and paleography it is evident that the inscriptions of all the
11 12th year opposite the second means 14th (12 plus 2) year. This is quite evident from the TepkA6 piller inscription of Arikesari lines 38-57 (Trau. Arch. Series, Vol. 1, pp. 99-102).
