The most interesting part for me was learning more about Poseidon; about his life, where he was born, how he became god of the sea, etc. I found out that Poseidon was given the trident by his uncle, the original Cyclopes.
One of my favorite subjects in the world is Greek mythology, but other mythology does interest me, as well.
During the World History Fair there were approximately 10 tables with something about mythology. Most of them were Greek mythology, only one was Egyptian. I learned that the original Egyptian god of the dead was Osiris and his nephew took over. It was cool because I did not know much about Egyptian mythology and I liked learning about one of their gods.
