1911 Encyclopædia Britannica/Bombard
BOMBARD (derived through Med. Lat. and Fr. forms from Gr. βομβεῖν, to make a humming noise), a term applied in the middle ages to a sort of cannon, used chiefly in sieges, and throwing heavy stone balls; hence the later use as a verb (see Bombardment). The name, in various forms, was also given to a medieval musical instrument (“bombard,” “bumhart,” “pumhart,” “pommer”), the forerunner of the bass oboe or schalmey. At the present day a small primitive oboe called bombarde, with eight holes but no keys, is used among the Breton peasants.
