Celtiberian in the context of the Paleohispanic languages

Celtiberian or Northeastern Hispano-Celtic is an extinct Indo-European language of the Celtic branch spoken by the Celtiberians in an area of the Iberian Peninsula lying between the headwaters of the Duero, Tajo, Júcar and Turia rivers and the Ebro river. This language is directly attested in nearly 200 inscriptions dated in the 2nd century BC and the 1st century BC, mainly in Celtiberian script, a direct adaptation of the northeastern Iberian script, but also in Latin alphabet. The longest extant Celtiberian inscriptions are those on three Botorrita plaques, bronze plaques from Botorrita near Zaragoza, dating to the early 1st century BC, labelled Botorrita I, III and IV (Botorrita II is in the Latin language). In the northwest was another Celtic language, Northwestern Hispano-Celtic, that was somewhat related to Celtiberian.

Enough has been preserved to show that the Celtiberian language could be called Q-Celtic (like Goidelic), and not P-Celtic like Gaulish. For some, this has served to confirm that the legendary invasion of Ireland by the Milesians, preserved in the Lebor Gabála Érenn, actually happened.
