A drinking horn or musical instrument made from the horn of a buffalo or wild ox.
From 'buffle' (buffalo, from Old French) combined with 'horn,' referring to practical vessels and instruments crafted from the actual horns of large horned animals.
Medieval lords and warriors used these as both drinking vessels and signaling instruments—the same object could hold mead at a feast and then summon troops to battle with its deep, resonant tones.
