Tiamat's son, Marduk, in the earliest versions of the myth, attacks her, but she merely eats him and spits him out anew. It is in later versions that Marduk splits his mother in two halves, killing her and taking her power. This is when she is renamed the Dragon of Chaos and when murdering dragons essentially symbolizes demonizing women's menstrual powers and menstrual cycles. It can be seen in the myth of Lilith, who was an ancient dragon, Laila, the night. Others are Medusa, Echidna, Charybdis, Scylla, Hydra, the Unsas of Arabia, who when honored would give advice and oracles. As soon as patriarchy gained sway, the dragon blood, which originally brought forth the earth and its beings in the earliest myths, was now cursed. Slaying dragons then became the next era of mythology, where menstrual blood turns taboo and even synonymous with evil needing to be slain by heroes. The power of the female creative force was essentially removed and taken by the hero murdering his dragon mother for her menstrual blood, dragontime blood, blood of peace and symbolic of Red Goddess immortality.
