Greeks would pick a god that was a patron of their trade or hobbies. A farmer would pay homage to Demeter, a hunter would pray to Artemis, a blacksmith to Hephaestus, a warrior to Ares, a scholar to Athena, a mother to Hera, or a wine maker would worship Dionysus. Also certain times of the year would demand a sacrifice to certain gods.
