The Turkish name for Greece, Yunanistan, literally means "Land of the Ionians." Ionia also yielded the name for the country in Arabic and Hindi (Yunan). The place name (which Herodotus credits to an ancestral Ion, son of Apollo and Creusa) is probably pre-Greek, perhaps related to Sanskrit yoni "womb, vulva," and a reference to goddess-worshipping people.
"The Ionians delighted in wanton dances and songs more than the rest of the Greeks ... and wanton gestures were proverbially termed Ionic motions." [ThomasRobinson, "Archaeologica Graeca," 1807]
