South Indian stone relief

[Jens Nordlunde]

The pictures are from an old stone relief from South India, and shows a fighting scene. Look at the sword the man to the right is using, it is almost a katar hilt, but the weapon is surely a sword, as it is too long to be a dagger. I am not sure, but I seem to remember that the text said it was from between the 12th and the 15th century. Can anyone tell more about it?
