Against a background of anxious evocation of Dionysiac rites, Euripides'Heraclesstages the extreme degradation of the tragic hero who, as a consequence of the hatred of a divinity, loses his heroic traits and above all his human ones in the exercise of brutal violence. By comparing Heracles in the grip of madness to a furious bull assailing its prey, the tragedian clearly shows the inexorability of the divine will and its arbitrariness, and emphasizes madness itself through images traditionally associated with the (...) bull. However, the reference to monstrosity and animals does not only involve Heracles, but also concerns the representation of Lyssa, the demon of madness sent by Hera to induce Heracles to slaughter his own family. This representation of Lyssa includes the monstrous and disturbing Gorgon and the dog, set alongside the metaphor of hunting, which in turn highlight the link between the demon and the Erinyes, those other bringers of madness.
