Halmidi inscription
The Halmidi inscription is the oldest known Kannada-language inscription in the Kadamba script. While estimates vary slightly, the inscription is often dated to between 450 CE - 500 CE. The inscription was discovered in 1936 by Dr. M. H. Krishna, the Director of Archaeology of the (princely) State of Mysore (present-day Karnataka region of India), in Halmidi, a village in the Hassan district. The original inscription is kept in the Office of the Director of Archaeology and Museums, Govt. of Karnataka, Mysore, and a fibreglass replica has been installed in Halmidi. Discovery and dating 

In a report published in a Mysore Archaeological Department Report (MAR) in 1936, Krishna dated the inscription to 450 AD, on paleographical grounds. Later scholars have variously dated the inscription to 450 AD, 470 AD, 500 AD, "about 500", and "end of the fifth century A. D. or the beginning of the 6th century A.D." Epigraphist, D. C. Sircar has dated the inscription to "about the end of the 6th century." Epigraphist, K. V. Ramesh has written about the differing estimates:

He also hypothesized that, compared to possibly contemporaneous Sanskrit inscriptions,  "Halmidi inscription has letters which are unsettled and uncultivated, no doubt giving an impression, or rather an illusion, even to the trained eye, that it is, in date, later than the period to which it really belongs, namely the fifth century A.D."

Epigraphist G. S. Gai however disagrees with the view that Halmidi is a record of the Kadamba dynasty identified with King Kadamba Kakusthavarman. According to , the inscription, which is dedicated to "Kadambapan Kakustha-Bhaṭṭōran," refers to another ruler, Kakustha of the Bhaṭāri family, who is explicitly identified in line 13, ";" in addition, the inscription does not "include any of the epithets like , , and most important " that are a part of all Kadamba inscriptions. Textual analysis 

The inscription is in verse form indicating the authors of the inscription had a good sense of the language structure. The inscription is written in pre-old Kannada (Puruvada-hala Kannada), which later evolved into old Kannada, middle Kannada and eventually modern Kannada. The Halmidi inscription is the earliest evidence of the usage of Kannada as an administrative language. Text

The pillar on which the inscription was written stands around  high. The following lines are carved on the front of the pillar:
