Final answer:
Tiamat and Gaia are dynamic/round characters in their respective mythologies, featured as primordial earth deities associated with creation. Tiamat evolves into an antagonist in Babylonian myths, while Gaia remains a nurturing figure in Greek myths. These differences reflect the societies' cultural values and views on the gods.
Step-by-step explanation:
The characters Tiamat from Babylonian mythology and Gaia from Greek mythology are similar in that they are both primordial deities who personify the Earth and are associated with the creation of the cosmos. Their stories have dynamic qualities as they interact directly with other gods and forces, making them dynamic/round characters who influence the story actively rather than being unchanging or static/flat characters.
However, the evolution of these characters is different. Tiamat eventually becomes an antagonist in the Babylonian epic Enuma Elish, where she is defeated by the god Marduk. This conflict delineates her as a complex character with shifting roles from creator to destroyer. Conversely, Gaia's role remains more constant as the nurturing earth mother throughout Greek mythology, though she does instigate plots against the ruling deities when her children are threatened.
These differences may be due to the varying mythological and cultural views of the societies that created these deities. Babylonian mythology often had gods that reflected their values of kingship and combat, while Greek mythology had a pantheon that often represented various aspects of human life and the natural world.
