Cabeiri were deities of flowering and fertility, divine craftsmen, sons of Hephaestus.
The geographer Strabo reported that in Lemnos, the mother (there was no father) of the Cabeiri was Kabeiro herself, a daughter of Proteus (one of the "old men of the sea") and a goddess whom the Greeks might have called Rhea.
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 that an inscription at Lemnos indicates parapaizonti, the one who "jests along the way".
