@gotthearse Greek mythology is fun. There are a gang of gods and goddesses who hang out on Mount Olympus. They are utterly unlike the Christian concept of god as they continuously interfere in the lives of men and woman but are completely unreliable and capricious.
Zeus, the head of the gods, in particular keeps having sex with mortal women. In these encounters he is usually in a different form such as a swan or a shower of rain. A lot of these encounters are quite rapey. But if you read about them in a children's book you just think 'Oh Zeus ran off with Europa while disguised as a bull, cool' and not 'Oh shit, this is horrific'
There are also multiple stories about Greek heros eg Jason, Theseus, Herakles. They are also helped out by gods along the way, usually they have one that backs them despite however awful they might be.
Finally there is the Trojan War. It lasts 10 years, most of which is spent with the Greeks falling out amongst themselves. At the end, the Greeks go home but their actions come back to haunt them. Odysseus spends 10 years trying to get home (OK a lot of those years are spent hanging out with sexy nymphs) and has to fight for his kingdom. Agamemmon, who is an all round shit, comes home to discover his wife hates him for entirely understandable reasons, and gets murdered, This sets up a multi-generation plot where everybody dies. It's like the best soap you ever watched.
The Greek gods all get important into Roman religion too. But then they are more of a state religion that something all the Romans believe.The Romans are massively into religion and very superstitious so collect gods from everywhere they go.
