The inscriptions of Thiruvadakudi Mahadevar or Panchanadeswara temple glean interesting information about the temple and village. Twelve inscriptions are copied from the temple complex in the year 1903 and all the inscriptions belong to Chola period, particularly of Middle Cholas. Few fragments are seen on the prakara walls probably of Nayak period. The inscriptions mention the deity as Thiruvadakudi Mahadevar and the village as Thiruvadakudi, a devadana neighbourhood of Allur. Thiruvadakudi was under the administration of Sabha, denotes the village a Brahmin settlement. The present Allur was two different villages in the medieval period, the northern part of the village a Brahmin settlement and also a devadana in the name Thiruvadakudi whereas the southern part of the village was a non-brahmin settlement known in the name Allur. Allur and Thiruvadakudi were under Uraiyur kurram in the early period, later in the Middle Chola period it was under the administrative division of Keralanthagavalanadu. However, an inscription of Kulottunga III gleans that the Uraiyur Kurram came under Rajagambiran Valanadu. The earliest inscription of this temple complex belongs to Parantaka Chola I and inscriptions of Rajaraja Chola I, Rajendra Chola I, Kulottunga III are also found in this temple complex. The inscriptions of Thiruvadakudi Mahadevar temple richly glean the administration, endowment, festivals and various rituals, consecration of deities in the temple.
The earliest inscription of this temple complex belongs to Parantaka Chola I. A sixth regnal year inscription of Parantaka Chola I records purchase of land by Pudi Madevadigal from the Isanamangam Parudai. The inscription details the boundaries for the land. Isanamangalam was a neighbourhood hub of Allur and Parudai was the Mulapparudaiyar, an assembly of the sabha villages. Pudi Madevadigal was the queen of Kannara deva, the half brother of Parantaka Chola I. A fifth regnal year inscription of certain Rajakesari records the son of feudatory Virasola Ilangovel (a) Orri Mathuranthaka endowed thirty kalanju of gold for burning a perpetual lamp in the sanctum for Parantakadeva.
Saiva sacred hymns Thevaram and Thirupathiyam were recited in the temple, an inscription of Rajadhirajadeva I records that certain Ambalattadi Thirunavukkaraiyan was appointed to recite in the temple and to draw thuni paddy daily from the temple treasury as remuneration. Besides, certain other rights and privileges were also guaranteed to him as per King’s order.
It is quite interesting to see nearly seven inscriptions speak about food offerings to the Brahmins who excelled in Vedas. Individuals, family, royal personalities also gifted for the cause. An inscription records certain Sandhi nagarattal, Kadan Nachchadevi, Nakkan Vennavalan each gifted gold to feed a Vedic brahmana. The inscription mentions Nakkan Vennavalan alias Thillai Azhagu was a Thalaikoli. As like, another inscription records thirty three kalanju of gold was gifted by Pirantagan Vallan queen of the feudatory Mathuranthaka Irukkuvel (a) Ilangovel to feed ‘uttama agaram’ to one vedic Brahmin daily. Uttama agaram was the food with good quantity and varieties viz., rice, kari, ghee, thayir, betel and areconut to be served for the feed. As paddy forms the medium of exchange, for the above said list, measures of paddy is mentioned for each dish including the measure for the helpers, in addition, all these to be meted out from one kalam of paddy. The inscription also mentions the gift of bronze utensil weighing 25 palam for serving the food. Both the inscriptions belongs to Rajaraja Chola I.
An inscription of Rajendra Chola I records a woman and her four sons from Vanarkkurai, a brahmadeya in Keezhar kurram gifted five kalanju of gold to feed five Vedamvalla brahmanas in the day of new moon. The inscription mentions Sendan Vikramakesari, his brothers Sendan Achapidaran, Sendan Kavali, Sendan Tirunilakandan, his mother Vikramakesari Ponni each gifting one kalam of paddy, collectively five kalam of paddy. Totally thirty kalam of paddy to be procured for the feeding out of the interest accumulated from the deposited gold and the responsibility of carrying out the endowment was undertaken by the Sabha. Another inscription of the same king gleans the arrangement made by the Sabha over the procurement of thirty kalam of paddy. It was to be procured from a ‘karsei’ named ‘Manarkadu Punsei thidal’ in addition, it states that once it was a fallow land.
Two inscriptions speaks about consecration of various deities in the temple. An inscription of Rajadhiraja deva I records the installation of the deity Umaskanda sahithar by Ogaiudaiyan Kariyudaiyan, an officer of Nadu cadre. The other deities gleaned through the inscriptions are Neelivana Vidangar and Pirattiyar, Pillaiyar, Pasupathadeva. It is quite interesting to see Pasupathadeva installed in this temple. The same inscriptions also details about the food offerings for the installed deities. The thirty seventh regnal year inscription of Kulottunga III records the consecration of Thirukamakottamudaiya nachiyar in the second prakara of the temple complex by a kaikola named Avathukathan.
The inscription also refers measures, Angadi kudingaikal was a gold measure was in usage in this region during Rajaraja Chola I period, as like, Devar pandarakal, probably a standard paddy measure in the temple gleaned in an inscription.
