Ziselmius

Ziselmius, or Zibelmius or Zisemis (Ancient Greek: Ζισέλμιος) was a chieftain of the Thracian Caeni tribe and son of Diegylis. Both Ziselmius and his father are mainly known due to the writings of Diodorus of Sicily who described them as cruel barbarians and guilty of acts of incredible savagery.
