How old is the Kora, and from where does it origin?

[sirupate]

Hello Jens,

The ‘Kora’, which could produce deadly blows with its forward curved and broad tipped blade, appears, for the first time, in one of the sculptural panels carved in the second gate of the Mukhalingesvara temple at Mukhalinga,, the capital seat of the Eastern Ganga monarchs

Has anyone confirmed that they are kora/khunda? or is it just M. L. Nigam's interpretation of what the image might be?

The Khunda according to the Nepalese historians I have been talking to is not the favourite weapon of the Gorkhas, this appears to be a myth born from early British writers who never even went to Nepal.
