Dacian Draco

The Draco was an emblem and artifact that became popular with the Dacian cavalry. One of the really neat things about it was that it whistled. Yes, whistled. The draco was used as a war standard, and was made of bronze. When wind blew through the mouth, the Draco would emit a whistle that was eerie and frightening to those that heard it. It is considered to be one of the sources for the concept of a dragon. (See more)
