Foghorn, from Italian mus- (Greek 'mus-
ic' ) colo (Latin 'neck'). Originally an instrument made from the neck and lungs of a
bull, operated by two men, each applying their full weight to a lung. The resulting expulsion of
air through the neck caused a powerful low-frequency tone that could be heard for many miles and carried especially
well over
water. The 'muscolo' required strong support and was usually affixed amidship to the main mast. Recharging was difficult as each 'muscolier' took turns inflating the lungs by exhaling back into the neck. Commonly found on Adriatic ship traffic until the 4th century
AD, when they began to be replaced by mechanically driven ram horns.
