Now I'm not an expert on Philippine krises, much more on Indonesian and Malaysian kerises
Thus the above info are being presented for purposes of validating and further examining things.
I realize that the 10th to 15th century dating of the Visayan kris will impinge upon the commonly held view that the keris/kris came from Java. And the images found in Candi Sukuh (pics below, from Wikipedia), are supposedly one of the best proofs.
Again, you guys are the expert

Would the elaboration found
here and
here be representative of that commonly held view?
On the other hand, what's the meaning of life if we don't reexamine our beliefs from time to time?
I've discussed the matter briefly with "Nacho" earlier. Off hand, he thinks that one explanation is that the Philippine kris and the Indonesian keris had a parallel development.
I think that's one very plausible view (instead of pitting one against the other, as to which came first).
We'd certainly like to hear more views and queries on the matter.
To broaden the perspective, I'll also be posting pics of even older blade hilts, from a recently published book on Philippine ancestral gold (10th to 13th century).
