Mithraism
Mithraism was a Roman mystery religion centered on Mithras, practiced mainly by men in small groups that met in underground temples called mithraea.
Mithraeum: A sanctuary used for Mithraic worship, commonly designed as an underground cave or dining room. These compact sanctuaries shaped the religion’s communal rites and cave-like symbolism.
Mithras: A god worshipped in Roman Mithraism, represented in its central bull-killing scene. The cult took its name and defining imagery from this deity.
Mithraic mysteries in the Roman Empire: The Roman-era worship of Mithras, attested from the late first century CE across the empire. The cult’s geography and chronology are reconstructed from its sanctuaries and inscriptions.
Eleusinian Mysteries: Greek initiation rites centered on Demeter and Persephone, celebrated at Eleusis near Athens. They offer a prominent Greek mystery tradition with different myths, rites, and institutional setting.
Tauroctony: A scene depicting Mithras killing a bull, central to the iconography of Roman Mithraism. Its repeated placement in mithraea made the bull-killing image the cult’s defining ritual focus.
Roman religion: The diverse public, household, and communal religious practices of ancient Rome. Mithraism developed within Rome’s wider landscape of gods, rites, and associations.
Mithraic archaeology: The study of Mithraic sanctuaries, images, inscriptions, and material remains. Archaeological evidence is the principal source for a cult with few surviving texts.
Cult of Isis: The worship of the Egyptian goddess Isis, which spread widely through the Roman world. Like Mithraism, it crossed regional boundaries, but its imagery and participation differed.
Mithraic initiation: A process by which participants entered increasingly restricted levels of Mithraic membership. Initiation structured access to the group’s ceremonies and sacred knowledge.
Mystery religion: An ancient religious tradition involving restricted rites and initiation for participants. Mithraism’s initiation and limited membership place it within this broader pattern.
