I dunno about the Med
eans' bows, but in some wealthy bronze/iron age civilisations people showed off their wealth by sheathing their bows in beaten sheets of bronze or copper and/or gold with lots of intricate metalwork designs. These were usually either for ceremonial purposes or for the hunt. But the basic construction remained, I believe, wood or horn (for smaller bows). I could be more specific if I could be bothered sorting through 15 boxes of books in the garage. But I can't!
