War horns were designed to intimidate the enemy, and came in many shapes and sizes. Perhaps the most interesting was the Celtic 'carnyx'. As long as a man is tall, the bell of the horn often depicted an animal head; examples of snake, horse and boar heads have been found across Europe. Producing a long drawn-out 'scream', some historians believe the instrument was deliberately sabotaged to stop outsiders from playing it. This is because a number of carnyx discovered in France in 2004 were missing a key component in the bell of the horn, preventing them from making their infamous scream.
