And then there was Demeter, the goddess of the harvest, with her beloved daughter Persephone on her lap.
Next there was Poseidon, the lord of the sea and Zeus’s brother, and then the four children of Zeus: Athena, goddess of wisdom; the twins Apollo (god of light and music) and Artemis (goddess of the hunt); and Dionysus, the god of wine.
"The early Romans worshipped their deities without images.
Indeed, they seem to have worshipped them without personification of any kind.
Of course, on some occasions, even when one took the precaution of attempting to appease them, the gods might just be in a foul mood and decide to let a human suffer – there are many stories like this in Greek mythology.
So what did all these gods do all day long other than relax in their comfy palaces?
While they are considered mythology to modern people, it is important to keep in mind that, during that time, they were considered religious practices and were not looked upon as mythology or fiction.
Greek mythology, although it focused on a hierarchy of deities, also allowed for the presence of demi-gods, who were a combination of human and god. Under Alexander, "the monarch and his consort were worshipped as deities in their lifetime, rather than being posthumously heroised as demigods" as occurred in other contemporaneous societies, like Egypt (Jones & Pennick 1997, p.23).
Zeus’s eldest sister Hestia also lived with these twelve great gods.
She was the goddess of the hearth, and tended the sacred fires of the gods.
