|Iris the rainbow goddess, from google.|
When I was little it was always Greek mythology. I knew all about the gods and goddesses, the gorgons and cyclopes, heroes and nymphs. Nowadays, not much has changed, only it's grown to include Roman mythology, and some Norse and Egyptian, and a few more.
One of the best books I've ever read that included mythology was Neil Gaiman's 'American Gods'. Not only was it a very good introduction to Norse mythology, but it was also very interesting, and occasionally funny. Do read it if you get a chance.
Another series of books is Rick Riordan's Percy Jackson series, and the Heroes of Olympus series. He's also done an Egyptian Mythology series that I've yet to read.But though they're a series for children, they're actually very good. They include many many mythological stories and characters from Greek mythology (and some roman), so actually you learn quite a lot from it too. If you already know a lot of mythology, like me, you can see all of the stories intertwining and appreciate the subtleties if his stories. Maybe read these too?
Hercules (the Disney film) has to get a mention here because it's one of my favourite films. It doesn't deal with any of his trials apart from the Hydra and a scene where they all flash by in a good old song and dance (Zero to Hero, good song). However, it's funny and endearing and I like all the references.
Probably my favourite person/god in all mythology is Iris, the Greek goddess of rainbows, also a messenger goddess.
I do have to say, the Roman God Bacchus (or Dionysus in Greek Mythology) was represented amazingly well in Disney's Fantasia. He was the philandering drunk guy riding the donkey in the wine and thunder scene. Zeus obviously wasn't very happy with him.
