Great pictures BluErf. That first ivory (?) Durga with the balls of fire being emitted from her mouth is just too cool.
I tend to agree that Cedric's Bali example might more likely be Nava Sari. The object held behind the back appears far too stiff to be meant as a vale and looks very much like a stylized grain sheaf. Compare to the obvious fabic material held in Blu's first example.
As for Jensen's method of dating, the major problem with it (aside from it's vagueness) is that the large majority of keris have NOT been collected by museums, so it only allows us to say that a very small precentage of keris are at least this old. Since i have yet to acquire a single keris in my collection from a museum source it is of little help to me in dating my own blades. I have been fortunate to acquire most of my blades from learned sources who have spent many decades researching and studying keris in order to determine age, style, etc. as best they can. Boedhi Adhitya is right to question Tangguh, but for unprovenenced keris it is still the best method available when understood and done correctly. Something i am certainly NOT very good at, but fortunately i have sources that i feel are much more knowledgable than i that i can trust.
