Mysteries of Isis

The mysteries of Isis were religious initiation rites performed in the cult of the goddess Isis in the Greco-Roman world. They were modeled on other mystery rites, particularly the Eleusinian Mysteries in honor of the Greek goddess Demeter, and originated sometime between the third century BCE and the second century CE. Despite their mainly Hellenistic origins, the mysteries did allude to beliefs from ancient Egyptian religion, in which the worship of Isis arose. By undergoing the mystery rites, initiates signaled their dedication to Isis, although they were not required to worship her exclusively. The rites were seen as a symbolic death and rebirth, and they may have been thought to guarantee that the initiate's soul, with the goddess's help, would continue after death in a blissful afterlife.

Many texts from the Roman Empire refer to the mysteries of Isis, but the only source to describe them is a work of fiction, the novel Metamorphoses, written in the second century CE by Apuleius. In it, the initiate undergoes elaborate ritual purification before descending into the innermost part of Isis's temple, where he has an intense religious experience, seeing the gods in person.

Some aspects of the mysteries of Isis and of other mystery cults, particularly their connection with the afterlife, resemble important elements of Christianity. The question of whether the mysteries influenced Christianity is controversial and the evidence is unclear; some scholars today attribute the similarities to a shared cultural background rather than direct influence. In contrast, Apuleius's account has had direct effects in modern times. Through his description of them, the mysteries of Isis have influenced many works of fiction and modern fraternal organizations, as well as a widespread, though false, belief that the ancient Egyptians themselves had an elaborate system of mystery initiations.
