Through Common Era, Roman Empire and Christianity

Many texts from the Roman Empire refer to the Isis mysteries, but the only source to describe them is a work of fiction, the novel The Golden Ass, 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 experiences a symbolic death and rebirth and 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 they 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, the mysteries of Isis have influenced many works of fiction and modern fraternal organizations, as well as a widespread belief that the ancient Egyptians themselves had an elaborate system of mystery initiations.

Origins

Greek and Egyptian precedents

Greco-Roman mysteries were voluntary, secret initiation rituals. They were dedicated to a particular deity or group of deities, and used a variety of intense experiences, such as nocturnal darkness interrupted by bright light, or loud music or noise, that induced a state of disorientation and an intense religious experience. Some of them involved cryptic symbols. Initiates were not supposed to discuss the details of what they experienced, and modern understanding of these rites is limited by this secrecy. The most prestigious mysteries in the Greek world were the Eleusinian initiations dedicated to the goddess Demeter, which were performed at Eleusis near Athens, from at least the sixth century BCE to the end of the fourth century CE. They centered on Demeter's search for her daughter Persephone. Eleusinian initiates passed into a dark hall, the Telesterion, and were subjected to terrifying sights before entering a room brightly lit by fire. There the hierophant who presided over the ceremony shouted a cryptic announcement that may have alluded to the birth of the god Ploutos and displayed objects that represented Demeter's power over fertility, such as a sheaf of wheat.

In the mysteries of the god Dionysus, which were performed in many places across the Greek world, participants drank and danced in frenzied nocturnal celebrations. Dionysian celebrations were connected in some way with Orphism, a group of mystical beliefs about the nature of the afterlife.

Isis was originally a goddess in ancient Egyptian religion, which did not include Greek-style mysteries, although it did contain elements that resembled those in later Greek mysteries. Pharaohs underwent a consecration, related to their coronation rites, in which they were said to have close contact with the gods. Priests may have also undergone a consecration ceremony of some kind, connected with the specialized religious knowledge or training required for their positions. Ancient Egyptian funerary texts contained knowledge about the Duat, or underworld, that was characterized as profoundly secret and was believed to allow deceased souls to reach a pleasant afterlife. Some Egyptologists, such as Jan Assmann, have suggested some funerary texts were also used in priestly consecration rituals; Assmann argues that "initiation into the temples and cults of Egypt anticipated and prefigured the ultimate initiation into the mysteries of the realm of the dead." Other Egyptologists contest the idea that funerary texts were ever used in rituals by the living.

An element of Greek mysteries that did not exist in Egypt was the opportunity for ordinary individuals to undergo initiation. The most sacred rituals in Egyptian temples were performed by high-ranking priests out of public view, and festivals formed the main opportunity for commoners to participate in formal ceremonies. Some of these festivals reenacted events from Egyptian mythology, notably the Khoiak Festival in honor of Osiris, the god of the afterlife and the mythological husband of Isis, in which Osiris's mythological death, dismemberment, and restoration to life were played out in public view. Greek writers called these Egyptian rites "mysteries". Herodotus, a Greek historian writing in the fifth century BCE, was the first to do so. He used the term for the Khoiak Festival, likening it to the mysteries of Dionysus with which he was familiar, because both took place at night and involved a myth in which the god in question was dismembered. He further said that the Greek worship of Dionysus was influenced by the worship of Osiris in Egypt.

Greek writers who came after Herodotus viewed Egypt and its priests as the source of all mystical wisdom. They claimed that many elements of Greek philosophy and culture, including their own mystery rites, came from Egypt. The classicist Walter Burkert and the Egyptologist Francesco Tiradritti both argue that there is a grain of truth in these claims, as the oldest Greek mysteries developed in the seventh and sixth centuries BCE, at the same time that Greece was developing closer contacts with Egyptian culture. The imagery of the afterlife found in those mysteries may thus have been influenced by that in Egyptian afterlife beliefs.

Spread of the Isis cult

Isis was one of many non-Greek deities whose cults diffused beyond their home lands and became part of Greek and Roman religion during the Hellenistic period (323–30 BCE), when Greek people and culture spread to lands across the Mediterranean and most of those same lands were conquered by the Roman Republic. Under the influence of Greco-Roman tradition, some of these cults, including that of Isis, developed their own mystery rites. Much of Isis's cult involved activities that were far more public than the mystery rites, such as the adoration of cult statues within her temples, or outdoor festivals such as the Navigium Isidis, yet scholars often regard the mysteries as one of the most characteristic features of her cult.

The Isis cult developed its mysteries in response to the widespread belief that the Greek mystery cults had originated with Isis and Osiris in Egypt. As the classicist Miguel John Verlsuys puts it, "For the Greeks, the image of Egypt as old and religious was so strong that they could not but imagine Isis as a mystery goddess." Isis's devotees may have adapted aspects of Egyptian ritual to fit the model of the Eleusinian mysteries, perhaps incorporating Dionysian elements as well. The end product would have seemed to the Greeks like an authentic Egyptian precursor to Greek mysteries. Many Greco-Roman sources claim that Isis herself devised these rites.

Scholars disagree on whether the mysteries developed before the time of the Roman Empire, as the evidence about them from the Hellenistic period is ambiguous. Yet they could have emerged as far back as the early third century BCE, after the Greek Ptolemaic dynasty had taken control of Egypt. The Ptolemies promoted the cult of the god Serapis, who incorporated traits of Osiris and of Greek deities like Dionysus and the underworld god Pluto. Isis's cult was conjoined with that of Serapis. She too was reinterpreted to resemble Greek goddesses, particularly Demeter, while retaining many of her Egyptian characteristics. The mysteries of Isis, modeled on those in Demeter's honor at Eleusis, could have been developed at the same time. According to the Greek historian Plutarch and the Roman historian Tacitus, a man named Timotheus, a member of the Eumolpid family that oversaw the Eleusinian mysteries, helped establish Serapis as a patron god in the court of the Ptolemies. The classicist Jaime Alvar Ezquerra suggests that Timotheus could have introduced elements of the Eleusinian mysteries into the worship of Isis at the same time. Another possibility is that the mysteries emerged in Greece itself, sometime after the Isis cult became established there and came into direct contact with Demeter's rites at Eleusis.
