The year of first "Kudamulukku Peru Vilaa" (Kumba Abhisekam ceremony) of Thanjavur "Rajarajaeswarem Thirukkoyil"
The greatest Tamil Emperor of Tamil Nadu India of the medieval period was the Rajaraja Chola- 1 (A.D.985-1014).
The Kannada Inscription of the region Balmuri in Mysore District refers to conquests made by the Chola general Panchavan Marayan alias Mummudi Chola-Nagandavaranam. This inscription is dated the 28th year of Rajaraja Chola - 1 being Saka year 934. Hence the year of accession of Rajaraja - 1 on Chola throne = (934-[28-1]) = Saka Year 907.
This is further confirmed by another Inscription of the region Kallahalli in Mysore District dated 27th year of Rajaraja Chola - 1 being Saka year 933. That is (933-[27-1]) = Saka Year 907.
It has been determined by the Historians of India that any Saka year + 78 =Christian Year expressed in terms of A.D. Hence Saka year 907 = 907 + 78 =A.D.985. We are aware Saka year 907 covers the period of last 9 months from April A.D.984, and the period of first 3 months up to March A.D.985.
terms of Christian era would have been between January A.D.985 to March A.D.985. However for our purpose we will take the mean of this period and approximately conclude that Rajaraja Chola - 1 date of accession on the Chola throne was mid February A.D.985.
Now from one of the Thanjavur Rajarajaeswarem Temple Inscription we note that " .in the 25th year& 275th day Rajaraja Chola, that Udaiyaar Sri Rajarajathevar gave a copper pot to be kept on`thari' of the copper sthupi of "Sri Vimanam" of Sri Rajarajaeswarem Udaiyaar ".Hence it is understood that this was in the year A.D.985 Februrary + [25-1]years + 275 days (9 months) = A.D.1009 February plus 9 months = A.D.1009 November.
We also note from same inscription in this same temple that " in the 26thyear & 20th day " .Ko Rajakesarivarman alias Sri Rajaraja Thevar ..gave `thaanam' .at the `Thirukkattrali' (granite stone temple) which (he says) "I got it constructed Sri Rajarajaeswaremudaiyaar ".Here it is very clear that in his 26th year & 20thday (1 month approx) = A.D.985 February + [26-1] years + 1month = A.D.1010 February plus 1 month = A.D.1010 March, the construction of the Rajarajaeswarem temple was complete.
Thusit is confirmed that the "Kudamulukku Peru Vilaa" of Thanjavur Rajarajaeswarem Thirukkoyil took place in between A.D.1009 November and A.D.1010March.
If we take the mean of this period we arrive at an approximately accurate year and month when the "Kudamulukku Peru Vilaa" of Thanjavur Rajarajaeswarem Thirukkoyil took place being in A.D.1010 mid January.
This year being A.D.2010, the Tamil Nadu Government under the `great initiative' of the Honourable Chief Minister Kalaignar M. Karunanithi is celeberating the 1000th year (2010 - 1010) of completion of construction of Thanjavur Rajarajaeswarem Thirukkoyil (temple) also known as Periya Koyil, on September 25th & 26th more fittingly as a mark of highest appreciation of the great "architectural marvel" produced in granite stone, in reverence of the "God Siva" (i.e.God- as Siva) by Emperor Rajaraja Chola - 1.
It will be more fitting should the Tamil Nadu Government in this year of this great event rename the "Chennai International Airport" which is presently being developed into a ultra modern Airport - as "Rajaraja Cholan International Airport" in memory of the great son of the soil, which will give a world exposure and recognition to this great Tamil Emperor of Tamil Nadu.
