The name in the headword is closer to the goddess's name in other Anatolian cultures, e.g. Hittite, than is Greek Kubele (kappa 2586) or Cybele and may be the Phrygian name. The etymology from Greek kubista=n (kappa 2598) 'to tumble, turn cartwheels' is highly implausible (cf. kappa 2602 and note [5] there). The Greek word from which we derive 'enthusiasm' refers to the presence of a god in the human body, as in the mystery rites of Cybele, Dionysus and other gods, perhaps caused by alcohol or other stimulants.
[1] Homer, Iliad 5.586, another implausible etymology from Greek ku/mbaxos.
[2] An understatement for a country in which the rites of Cybele and Attis were widespread. The best known site was that at Pessinus (pi 1381), from which the Romans received the sacred black stone (perhaps cubic, cf. the outdated but still useful attempt of R. Eisler to link these words with a pre-Semitic root surviving in the sacred Ka'aba at Mecca: Philologus 68, 1909, 118-151,169-204) installed in the temple of the Magna Deum Mater ('Great Mother of the Gods') on the Palatine, to which they attributed the victory over Hannibal.
