There are two inscriptions found in this hillock. First one is seen near to relief sculptures (right side of
Mahaveerar) and it was engraved in Grantha script and Sanskrit language. It is a mixture of prose and poetry. It explains that Rajamalla established two temples for
Jinaraja in Vidyadri (hillock) in Saka 815 (892-93 A.D). It also explains
Arunkal-anvaya (school of Jain Monks), which was adorned by illustrious pontiffs, who had successfully crossed the vast expanse of the sea of knowledge of all the sciences, belonged to
Nandi Sanga of
Jinendra Sanga. Though the inscription mentions two temples, the second one is not yet found. The second inscription which was engraved in Tamil (Tamil portion, prose) and Grantha (Sanskrit portion, poetry) characters, located at the foot of the hillock in the northern side of the temple. The Sanskrit portion explains the exaltation to the
Arunkal-anvaya belonging to the
Nandi Sanga of
Dravida Sanga. The Tamil portion records that Vajranandhi-Yogindrar, the disciple of Gunaviradevar who was the
Mandalacharya of
Arunkal-anvaya caused to be constructed a flight of steps. These steps (see the picture gallery) are still in good condition. Rajamalla II had built another Jain rock cut temple in Vallimalai in
Vellore district during the same 9th century C.E. This leads to the conclusion that some parts of northern Tamil Nadu was under the rule of this
Western Ganga King Rajamalla II. ==Picture gallery==
