In the same season Fayoles, the fourth King of Numidia
Numidia is an ancient region in Africa, north of the Sahara, that was under Roman rule. This territory was broken down into tribes and clans, and each tribe and clan was ruled by a different king. The fact that the king sent a hideously great mare to Grangousier is significant because "Numidian horsemanship, animal breeding, and cavalry tactics eventually contributed to later developments in Roman cavalry" (Numidia).
