"Is it really a Cockatoo?"

[Spunjer]

we could see how it resembles a bird's head. we could almost perceive the beak and the plume, but why is it that the middle part, the one we perceive as the eye, the shape stays the same, in that it has a somewhat triangular motif, regardless if it's a regular pommel, or the miniaturized version. the shape stays the same.
the Indonesians view their keris with the blade up. let's do that with the emphasis on the pommel...

...now it takes a whole new image. we can see the vestigial tail and head, and what we perceived as the eye becomes the wing. pretty neat, huh? i took the liberty in encircling the obvious parts

in the later part of the nineteenth century, when these pommels became even more spectacular, one could clearly see the sarimanok image; the head is more pronounced, and one could see the ruffled feathers on the tail.
