without restraint, did not practise marriage, abducted women, and lived uncivilised lives. They thus had a dual, half-man and half-horse nature, which represented the forces of Chaos. The role of centaurs as embodiments of Chaos is depicted on the upper frieze a jug from the Rogozen Treasure, where two winged centaurs are shown approaching from each side the goddess , who is herself in a pose where she holds a dog in each hand. These centaurs represented the forces of Chaos, who are creatures existing on the border between nature and culture, as having invaded the Cosmos at the end of the year, when the powers of order are depleted, and attempted to violate the virgin goddess, and by extension any potential bride. On the frieze, a bull is defeated by the lions or dogs of the goddess and sacrificed to save the world from Chaos.

The dragon's three heads personified the triple form of the monstrous opponent of in Indo-European mythology. The appearance of the Chaos-dragon was fluid, and across retellings its size could change, it had no fixed colour, and it could be either a snake or a lion (in Moesian folklore, it was a white bear). The dragon itself attacked fiercely and with deceit, caused ulcerous wounds, coiled around its victim and drank its blood, and moved by twisting and turning unlike any normal living creature, and this changeability was represented on Thracian gold objects by images of snakes mottled with scales. Other depictions of the Chaos-dragon showed it as
