What is "shivakotiacharya"

Shivakotiacharya (also Shivakoti), a writer of the 9th-10th century, is considered the author of didactic Kannada language Jain text Vaddaradhane (lit, "Worship of elders", ca. 900). A prose narrative written in pre-Old-Kannada (Purva Halegannada), Vaddaradhane is considered the earliest extant work in the prose genre in the Kannada language. Scholars are, however, still divided about when exactly the text was written, with claims ranging from before the 6th century to the 10th century.
