Moro Decoration

[kino]

So this is a style dating at least to the early 1800s. Is this date for the horizontal bands as in the diagram or the diagonal elements as in the three examples shown earlier, or both? Do you think it is called fingernail impression because of its shape or its method of manufacture?

Kianoko also appears on architectual elements of a Maranao Torogan (a Datu’s large house).
I don’t know if the horizontal predates the diagonal.
I leaning towards the shape of it being called kianoko, not the method.

What book is this from?
