— Diodorus Siculus around 60-30 BC (Histories, 5.30).

The word “carnyx” is derived from the Gaulish root, “carn-” or “cern-” meaning “antler” or “horn,” and the same root of the name of the god, Cernunnos (Delmarre, 1987 pp. 106–107). This is the name the Romans gave to the instrument. The original Celtic name is unknown.

Three carnyx players are depicted on plate E of the Gundestrup cauldron.
