This inscription is engraved on a rock called Maḍuvegala in the village of Aṁbagasväva in the Divigandahe Kōrale of the Hiriyāḷa Hatpattu, Kuruṇǟgala District. It is written in the Sinhalese script of about the sixth century and records that a named individual settled his debt and caused the cessation of his slavery to the royal monastery of Mayagara. Another, very similar inscription is written on the same rock (IN03220).
