Words beginning with "pa" frequently shifted to "ha" (for example, puli became huli, and paalu became haalu), and terms containing "va" were often replaced by "ba" sounds, as seen in the evolution of perbolal to Hebbal.

A significant inscription dated to 750 CE on a hero stone commemorates Kittayya, a resident of Perbolanadu (modern-day Hebbal), who bravely defended the region against a Rashtrakuta invasion.

Sripurusha's extensive kingdom encompassed present-day Kolar, Bangalore, Krishnagiri, Salem, Erode, Mandya, Mysore, Coorg, Chikamagalur, Shimoga, and Tumkur districts.

[4] Another significant artifact from Hebbal is a 750 CE Durga idol, bearing a fragmented Kannada inscription, now preserved in the Anjaneya Temple in Bhoopasandra.

This inscription records a land grant to the goddess Durga, suggesting the presence of an ancient shrine or temple dedicated to her in the region.

Scholars propose a potential link between this Durga idol and the Hebbal-Kittayya hero stone, suggesting that Kittayya himself may have venerated this deity.

The surrounding area was also a prominent agricultural hub and a crucial trade route connecting Bengaluru to Hampi and other regions, enhancing its significance within the broader network of the Ganga kingdom.

To ensure long-term preservation, a group of committed citizens, led by P. L. Udaya Kumar, a former tech professional and current Honorary Director of the Mythic Society Bengaluru Inscriptions 3D Digital Conservation Project team, initiated a crowdfunding campaign to construct a mantapa.

The funds raised enabled the construction of a mantapa designed in the Ganga architectural style, reflecting the period to which the inscription belongs.

Interestingly, the mounted warrior is depicted in an unusual kneeling position on the horse’s back, rather than the traditional seated posture.

This hero stone sheds light on the concept of Uralivu, illustrating how Kittayya bravely fought and sacrificed his life in defense of his town.

The text of the inscription in Purvada halegannada language and written in Ganga period Kannada script was deciphered by eminent epigraphist Dr. P.V.

[1] A literal translation of the inscription is: "When SriPurusha Maharaja was ruling the Earth, Pelnagattarasa was administering Perbbolalnaadu-30, Kittayya the brother-in-law of Arakommora of Kodandale clan attained Indra Loka in an uuralivu battle during a Rattavadi attack.

Sripurusha’s kingdom referred to as Gangavadi 96000[9] extended to the regions of modern-day Kolar, Bangalore, Krishnagiri, Salem, Erode, Mandya, Mysore, Coorg, Chikamagalur, Shimoga and Tumkur districts.
