Religion played a part in almost every aspect of civic life, so shrines, temples, altars, and dedications are conspicuous at almost every turn during a visit to the Athenian Agora. The author of this booklet shows where and how the major Olympian gods were worshipped, and then turns his attention to lesser-known deities, such as Hekate, the triple-bodied goddess of the crossroads. He argues that the cults of heroes, such as Theseus, one of the legendary founders of Athens, were much more popular than the official state religion focused on the Olympian gods.
