The Carnyx

From Wikipedia.

The ancient carnyx was a wind instrument of the Iron Age Celts, used between c. 200 BC and c. AD 200. It was a type of bronze trumpet with an elongated S shape, held so that the long straight central portion was vertical and the short mouthpiece end section and the much wider bell were horizontal in opposed directions. The bell was styled in the shape of an open-mouthed boar's, or other animal's, head.

It was used in warfare, probably to incite troops to battle and intimidate opponents, as Polybius recounts. The instrument's significant height allowed it to be heard over the heads of the participants in battles or ceremonies.
