The Hatan kavya text “Seethawaka Hatana” written by a warrior who was supposed to have fought in the Great Battle of Mulleriyawela include a narrative in which he refers to at least 5 chiefs who fought with Kasthana swords by name. These include Chiefs Kuruppu (of Korathota), Athulpana, Kahandawa, Weragoda and Wijeyakoon. The Mulleriyawela Battle occurred in 1559 and the text is dated circa 1585. I think this conclusively establishes the existence of Kasthana swords to mid 16th century and conforms my earlier note on the gift of a Kasthana sword to the Arachchi of the Illangama fighters Korathota (see picture above post #62). I need to re-locate my copy of “Rajasinghe Hatana” text which may provide additional reference to confirm the record
This also establishes the fact that Kasthana was originally used in war.
