While Demeter and Persephone were linked with fertility, growth and death, other Greek gods were associated with other aspects of life, often several different ones. Hermes, for example, is often simplified as the messenger god, but he also leads the souls of the dead to the underworld, guards the entrances to houses, looks after herds and flocks, is the god of money-making and of trickery. As well as the divine family of twelve Olympian gods, there were hundreds of minor deities: gods of healing, victory, childbirth, winds, rivers, trees, mountains.
