Goidelic was introduced
in Ireland by the Gallaeci
of Galicia, N.W. Spain circa
500 B.C. The Gallaeci
spoke an archaic Goidelic Q-Celtic tongue called Gallaic. The Gallaeci
are the Halstatt
Celts that settled in Galicia circa
800 B.C. In Ireland, Gallaic evolved into Primitive Irish.
Celtiberian was introduced
in N.E. Spain by the La Tene Celts that settled in the area circa
500 B.C. Celtiberian is also
Q-Celtic, but not Goidelic.
