"In an earlier part of this volume, it was shown that Raja kesarivarman alias Virarajendradeva I., the victory at Kudalsangamam, must have reigned in the period intervening between the reigns of Rajendradeva and of Kulottunga I., and that, apparently, his immediate predecessor was Rajakesarivarman alias Rajamahendradeva, and his immediate successor Parakesarivarman alias Adhirajendradeva. Since then, Professor Kielhorn’s calculations of the dates of an inscription at Belaturu and of another at Manimangalam (No. 29 above) have established the fact that Rajendradeva ascended the throne (approximately) on the 28th May A.D. 1052, while the reign of Kulottunga I. commenced (approximately) on the 9th June A.D. 1070. Further, Professor Kielhorn has shown that the date of the Manimangalam inscription of the 5th year of Virarajendra I. (No. 30 above) probably corresponds to Monday, the 10th September A.D. 1067, and that, consequently, this king ascended the throne in A.D. 1062-63.
That Rajamahendra reigned between Rajendradeva and Kulottunga I., may be concluded from an Alangudi inscription of the 6th year of Parakesarivarman alias Tribhuvanachakravartin Rajarajadeva (II.), which quotes successively the three following earlier dates : -
(a) Line 22. – “the third year of the lord Vijaya-Rajendradeva, who was pleased to conquer Kalyanapuram and Kollapuram and to fall asleep (i.e., to die in battle) on an elephant.” This statement must refer to Parakesarivarman alias Rajendradeva, who is known to have set up a pillar of victory at Kollapuram.
(b) L. 55.- “the third year of king Rajakesarivarman (alias) the lord Sri-Rajamahendradeva, who, while the law of Manu flourished (as) of old, rescued the great earth from being the common property (of other kings), dispelled (with his) sceptre the dark Kali (age), and was pleased to be seated on the throne of heroes under the shade of a red parasol.”
© L. 63.- “the thirty-fifth year of the glorious Kulottunga-Choladeva, who was pleased to rule after having abolished tolls.” This refers to Kulottunga I., who bore the surname Sungandavirtton, i.e., ‘the abolisher of tolls.’"

Saumyanatha temple – on the same place, left side
This is dated in Saka 1172, Saumya, Rishabha, ba. 15, Friday, Rohini corresponding to A.D. 1249, May 14, Saka year being current on which day there is stated to have been a solar eclipse. It records a gift of all the tolls including the ‘maganmai’ dues leviable at Nirandanur, for the expenses of the several festivals in the temple of Sokkapperumal, by one Perumal-Pillai the headman of Kaliyur and a toll officer, to secure the well-being of Madurantaka Pottappichchola Gandagopalar alias Manma-siddharasa. The record is incomplete.
