I see your point, and of course I agree.
Yet, I think even in connoisseurship, maybe we shall not completely forgot that "Appreciating what you like is the most natural, and easy thing in the world."
A connoisseur, in front of two tsuba (in this case) made by Natsuo for example, has to choose between those in some way.
There are several different aspect to be judged, like the overall quality in terms of craftsmanship and conservation, but also the feeling that the piece give to us; isn't to give this "feeling" a sort of goal for the artist?
This is the point in my view.
I had the opportunity to work metal with a great teacher and a wonderful person. This opportunity teached me a little bit how to recognize craftsmanship; so I think I can now see the technical qualities of this tsuba; yet, I can't recieve any "positive" feeling from that, neither knowing what the theme is about or who did the piece and in wich year.
This is much probably a fault of mine, just wanted to express this feeling, because maybe other people feels this sensation and try a way to express it through words (and also in a foreign language :? )
Hope you don't mind about this digression,
Regards,
Lorenzo
