Please note that while there is a tendency in some books of mythology and ancient Greek religion to treat the deities as a sort of godly Justice League, saying that Aphrodite is the goddess of love, Ares the god of war, Poseidon the god of the sea, etc., this is a very simplistic way to look at some unimaginably complex entities. While the gods may each have particular areas of interest, that doesn't mean that those areas make up the extent of what they can do. While there is some functional specialization, the borders are far from clear.

All festival information is based on Athenian practices (that's where most of the surviving information hails from) unless specified otherwise.
