A very interesting piece. It's always nice to see items that while, not strictly weaponry, are part of the paraphernalia that goes with warfare.
For me at least, too often I see a culture or a period only in terms of the weapons I have studied and have trouble imagining an accurate picture of the people, the way of life and the culture as my focus has always been the weaponry.
An item like this horn evokes a very strong picture of the people of the time and I'm grateful to have a wider understanding and expanded mental imagery because of it.
