Similar doubts were raised earlier because our only source on a Punic trader is the play "Poenulus" and the Carthaginian presented there is a rather humble merchant. An important part of the Punic culture seems to have consisted in their devotion to the gods, and their well-known units, called "Sacred Bands" by our Greek sources, are regarded as the elite troops of their time. These consisted of infantry troops and cavalry units. The latter were formed by young nobles of the city devoting their life to military training.
