In Greek mythology, the Cabeiri, (Cabiri, Kabeiroi, Greek: Κάβειροι) were a group of enigmatic chthonic deities. They were worshiped in a mystery cult closely associated with that of Hephaestus, centered in the north Aegean islands of Lemnos and possibly Samothrace —at the Samothrace temple complex— and at Thebes. In their distant origins the Cabeiri and the Samothracian gods may include Hittite, Thracian, proto-Etruscan, or Phrygian elements. The Lemnian cult was always local to Lemnos, but the Samothracian mystery cult spread rapidly throughout the Greek world during the Hellenistic period, eventually initiating Romans.
The ancient sources disagree about whether the deities of Samothrace were Cabeiri or not; and the accounts of the two cults differ in detail. But the two islands are close to each other, at the northern end of the Aegean, and the cults are at least similar, and neither fits easily into the Hellenic pantheon. The accounts of the Samothracian gods, whose names were secret, vary in the number and sexes of the gods, usually between two and four, some of either sex. The number of Cabiri also varied, with some accounts citing four (often a pair of males and a pair of females) of them, and some even more, such as a tribe or whole race of Cabiri, often presented as all male.
The geographer Strabo reported that in Lemnos, the mother (there was no father) of the Cabeiri was Kabeiro (Greek: Καβειρω) herself, a daughter of Proteus (one of the "old men of the sea") and a goddess whom the Greeks might have called Rhea.
In general Greek myth identifies the Cabeiri as divine craftsmen, sons or grandsons of Hephaestus, who was also chiefly worshipped on Lemnos. Aeschylus wrote a play called the Cabeiri, and the fragments that survive have them as a chorus greeting the Argonauts at Lemnos. showed them as prodigious wine-drinkers, and wine jars are "the only characteristic group of finds" from the Cabeirium of Lemnos. Walter Burkert suggests a raucous, burlesque character to the mysteries of the Cabeiri and notes an inscription at Lemnos indicates parapaizonti, the one who "jests along the way". First-fruits were offered to Zeus, Apollo, and the Cabeiri; Burkert also sees the offerings to Zeus and Apollo, father and son, as indicating an initiatory ceremony
Samothrace offered an initiatory mystery, which promised safety and prosperity to seamen. The secret of these mysteries has largely been kept; but we know three things about the ritual: the aspirants were asked the worst action they had ever committed;
The archaic sanctuary of Samothrace was rebuilt in Greek fashion; by classical times, the Samothrace mysteries of the Cabeiri were known at Athens, where Herodotus had been initiated. But at the entry to the sanctuary, which has been thoroughly excavated, the Roman antiquary Varro learned that there had been twin pillars of brass. He describes them as Heaven and Earth, denying the vulgar error that they are Castor and Pollux.
The mysteries of Samothrace did not publish the names of their gods; and the offerings at the shrine are all inscribed to the gods or to the great gods rather than with their names. But ancient sources tell us that there were two goddesses and a god: Axieros, Axiocersa, and Axiocersus, and their servant Cadmilus or Casmilus. Karl Kerényi conjectured that Axieros was male, and the three gods were the sons of Axiocersa (Cadmillus, the youngest, was also the father of the three); Burkert disagrees.
In Classical Greek culture the mysteries of the Cabeiri at Samothrace remained popular, though little was entrusted to writing beyond a few names and bare genealogical connections. Seamen among the Greeks might invoke the Cabeiri as "great gods" in times of danger and stress. The archaic sanctuary of Samothrace was rebuilt in Greek fashion; by classical times, the Samothrace mysteries of the Cabeiri were known at Athens. Herodotus had been initiated. But at the entry to the sanctuary, which has been thoroughly excavated, the Roman antiquary Varro learned that there had been twin pillars of brass, phallic hermae, and that in the sanctuary it was understood that the child of the Goddess, Cadmilus, was in some mystic sense also her consort.
The name of the Cabeiri recalls Mount Kabeiros, a mountain in the region of Berekyntia in Asia Minor, closely associated with the Phrygian Mother Goddess. The name of Kadmilus (or Kasmilos), one of the Cabeiri who was usually depicted as a young boy, was linked even in antiquity to camillus, an old Latin word for a boy-attendant in a cult, which is probably a loan from the Etruscan language, which may be related to Lemnian..
Diodorus Siculus said of the Cabeiri that they were Idaioi dactyloi ("Idaian Dactyls"). The Idaian Dactyls were a race of divine beings associated with the Mother Goddess and with Mount Ida, a mountain in Phrygia sacred to the goddess. Hesychius of Alexandria wrote that the Cabeiri were karkinoi ("crabs"). The Cabeiri as Karkinoi were apparently thought of as amphibious beings (again recalling the Telchines). They had pincers instead of hands, which they used as tongs (Greek: karkina) in metalworking.
It has been suggested that the Orphic mysteries may have had their origins with the Cabeiri.
