His most famous extant works in Kannada are "Shantipurana", written in "champu" style (mixed prose-verse classical composition style inherited from Sanskrit), "Bhuvanaika-Ramabhyudaya", a eulogical writing, and "Jinaksharamale", a Jain "Purana" and an acrostic poem written in praise of noted Jain saints and Tirthankars ("Jainas") in 39 chapters ("kandas"). "Ramakatha", a writing based on the Hindu epic Ramayana, of which only a few stanzas are available is also assigned to Ponna. Historians Kamath and Shastri are not certain whether his extinct classic, "Gatapratiagata", is in Kannada or Sanskrit. However, according to the professor L.S. Sheshagiri Rao of the Sahitya Akademi, the writing is in Kannada and belongs to the genre of "literary exercise".
