+Ancient Greek religion was a polytheistic system centered on the Olympian gods, practiced through public festivals, sacrifices, oracles, and mystery cults from the Archaic through Hellenistic periods. It had no single founding text, no professional priestly class, and no creed — participation in communal ritual was the defining act of piety. [^3]

+## Sanctuary Structure
+Greek worship centered on the *temenos* (sacred precinct), which contained an outdoor altar where sacrifices took place. The *naos* (temple) housed the cult statue of the deity but was not a congregational space — rituals occurred outside. Sanctuaries ranged from simple rural shrines to monumental complexes like the Acropolis at Athens or the sanctuary of Apollo at Delphi. [^1]
+
+## Hero Cults
+Alongside the Olympians, Greeks venerated heroes — deceased humans (often mythological warriors) who received worship at their tombs. Hero cults were intensely local: a hero protected a specific community and was propitiated with chthonic rites (offerings poured into the ground rather than burned upward). Prominent examples include Heracles, Achilles, and Theseus. [^4]
+
+## Household Religion
+Private worship (*oikos* religion) ran parallel to public cult. Households maintained shrines to Hestia (hearth goddess) and Zeus Ktesios (protector of the household store). The *herm* (a pillar topped with Hermes' head) stood at doorways as protection. Daily libations and small offerings were routine domestic acts. [^3]
+
+## Polis Religion
+Modern scholarship (Sourvinou-Inwood, 1990) frames Greek religion as fundamentally embedded in the *polis* (city-state): civic identity and religious identity were inseparable. The city organized, funded, and participated in festivals as a collective. This "polis religion" model has been refined but remains influential; Kindt (2012) and Eidinow & Kindt (2015) have expanded it to include personal and private dimensions. [^3]
+
+## The Oracle at Delphi
+The sanctuary of Apollo at Delphi was active from at least the 8th century BCE. The Pythia (priestess) entered a trance state to deliver oracles. Ancient sources described intoxicating vapors rising from a chasm; modern geological research (De Boer, Hale et al., 2001) identified intersecting fault lines beneath the temple emitting ethylene and ethane gases from bituminous limestone, providing a plausible physical basis for the Pythia's altered state. [^5]
+
+## The Eleusinian Mysteries
+The Mysteries at Eleusis, centered on the myth of Persephone's abduction by Hades and her return, promised initiates a blessed afterlife. They predated the Greek Dark Ages (attested from ~1500 BCE) and continued into the 4th century CE. Initiates drank the *kykeon*, a barley-and-mint preparation. Wasson, Hofmann & Ruck (1978) proposed the kykeon contained ergot-derived psychoactive alkaloids; this hypothesis remains debated, with a 2024 *Scientific Reports* study suggesting ergot alkaloids could have been detoxified to produce a milder psychoactive compound.
