This is another frieze reconstruction showing the birth of Athena from Zeus' head. Hephaestus is in the back with an axe (after having just cracked open Zeus' head with it) while the other gods look on. The myth has to do with Zeus swallowing Athena's mother (named Metis or Mind) to prevent a prophecy that her daughter/son would be more powerful than the father. So, he swallowed Metis, eventually producing Athena, fully armed, from his skull.
